After the latest firmware, the phone does not connect to Lenovo. Instructions on how to flash an Android so it won't flash. The main problems that arise after the firmware

There are a lot of koristuvachs, eager to give a new life to their devices, to flash them on their own, but, unfortunately, they will not be gone forever. Problems arise with system settings, options, and even starting in Recovery mode until you are able to use it again. How can the situation be corrected?

The main problems that arise after the firmware

On the iOS side, the Android platform is open, so fixing it is often easier, as one might think at first glance. Each person has different reasons and different ways. There is no single panacea for all situations, so they need to be looked at carefully.

The device does not stick in

Sometimes, after flashing the firmware of devices, you don’t want to go through those with a discharged battery. So, before you start flashing, you need to check to make sure your phone or tablet has enough charge. If the gadget does not connect, but the PC recognizes it, it is logical to charge it right away.

If the device does not work, or you may be tempted by the update mode, you need to take this chance quickly. Information on how to update the system to your phone using Recovery Mode will be discussed below.

Won't turn on and won't charge

If the device does not plug in and you don’t want to charge via USB, you can try charging the battery with your phone for help from the so-called toad.

"Toad" allows you to charge batteries directly from devices, no matter what type of device you have for your smartphone.

If it appears that the battery on the right is not in the battery, but the device is recognized on the PC, you will need to flash the phone again. It’s better to go to the service center, or you can work there and at home.

If your phone is missing an excessive version of firmware, it is recommended to install it. However, the best solution would be to download the file that is found on the publisher’s website, and not on a third-party web site. The firmware must necessarily fit the model of the device.

The file must be downloaded to the root folder of the MicroSD card and the installation can be printed using the Recovery mode. To start the mode, press the power button at once. For different phone models, this combination may be different. If you haven’t tried this option, you can try pressing the Home key and the same volume button.

Updated with standard ADB features

If your smartphone does not support SD cards, you can use ADB commands. This method is suitable for removal if the device is permanently re-enabled. The procedure is carried out in this way.

1. Turn off USB settings and run the ADB Run program on your computer. If you need a driver, download and install it. Select the Backup menu.

   In the main menu of the ADB Run program, select Backup

2. Click on Adb Restore.

   In the menu that has opened, click on Adb Restore

3. On the device itself, press the “Update data” button.

   Your device will prompt you to update your data, which you will need to confirm.

The device is gradually being re-engineered

When the phone is constantly re-engaged, control is lost. To turn it, you need to first check the battery, as the problem often stems from a malfunction. If the battery is not charged, you will need to reset the settings to factory defaults using Recovery Mode or in the settings themselves. A report about this is written below in the sections about the black screen and the use of the phone.

The device freezes on the splash screen

The problem lies in the fact that the flashed phone starts to start, but not on the logo. Then everything goes out, and the owner is left with nothing. This problem is called bootloop. The reason is the installed firmware, which is not suitable for a smartphone or tablet. Another option is to replace files in system sections of the OS. The device is tempted to launch those that gradually reclaim the system memory. It is logical that the destruction will inevitably occur.

The reason why the smartphone freezes is due to the installation of stupid firmware or failure to replace system files

The touch screen stopped working

If the touch screen stops working, you should immediately try to enter Recovery Mode. If the phone is switched to this mode and makes a backup copy of the data, roll back to the old version. Detailed instructions for the next section.

Just a black screen

If the phone is not activated and does not display the manufacturer's logo, and the phone enters update mode, it is obvious that you need to try to update the old version of Android. If the device does not enter Recovery mode, you need to go to the last resort: install a new version of the OS or a custom Recovery using a PC and ADB commands.

1. Turn off the update mode. Again, for each brand (or model) of smartphone/tablet, there are different combinations of keys for logging in:
   • in Samsung devices you need to press the power button on the “Vol+” device;
   • for Sony cameras - Power, Vol – and the camera on button;
   • for HTC – “Vol –” and Power before enabling Recovery mode.
2. In the Recovery menu, use the additional volume key (in some cases you can use the touch screen to move it) and select the item wipe data/factory reset. Press the life key to go to this menu.

   From the Recovery menu, select the item wipe data/factory reset

3. Confirm that you can delete data from your smartphone and log in to your account by selecting the appropriate option.

   We confirm that we have received the data of the koristuvach

4. Complete the process of downgrading to the old version of the OS, and then select the reboot system now item to exit the update mode and the date of the operating system will be displayed.

   Select the item reboot system now and check to restart the operating system

After successfully completing the described operations, the device will return to the latest version of Android.

After flashing the firmware, Recovery Mode does not work

After flashing the firmware, the Recovery Mode does not start, but the smartphone is connected and may be due to the incompatibility between the factory Recovery mode and the new OS version. A special update platform, such as CWM (ClockworkMod), can handle the situation. Install it using the Rom Manager program. There are also other, more complex methods for updating the firmware. For example, if you have a Samsung phone, it’s better than the Odin one. Many popular manufacturers create their own special software, like the Acer version.

To restart the device using Rom Manager, you need to revoke Root rights. This can easily be done using other utilities, such as Framaroot. If the rights of the super user have been revoked and the Rom Manager has been secured, you need to do the following:

After this, the files will begin to be encrypted, and then a notification will appear about those that need to be given Root rights to the program. Then the CWM installation will be completed.

The computer stopped working on the device

We first need to check the functionality of the USB port and install the drivers. If this did not help correct the situation, you can quickly use this instruction.

1. Turn down the setup mode until it is adjusted. For different smartphone models and different OS versions, the sequence of actions may vary. For example, for Sony Ericsson Xperia Arc based on Android 4.0.4, you need to select the “Features for Users” section in the settings, and then “USB Utilization”.

   Go to the “Functions for Retailers” section and select the setup mode

2. Confirm activation of the lifestyle mode by pressing OK.

   Click OK to confirm the transition to setup mode

3. Go to settings again and select Xperia.

   We know in the settings of the Xperia item and open it

4. Select the "Connection" item.

   Select “Connections” - this is the remaining row of the menu

5. Click on “USB Mode” and select “Media Transfer Mode”.

   Select the media transfer mode - the computer and mobile device can exchange files.

After these manipulations, the smartphone can be registered correctly on the PC again.

There is a sound on the device

The problem indicates that the custom firmware does not match the device. The solution is to reflash the device again, or with a different version. You need to upload the firmware file to a known card and replace the version using Recovery Mode.

However, right now you can try resetting your phone to factory defaults. This method is described below in the section about combating low speed code.

Report “Invalid IMEI” after flashing

The notification means that the IMEI was erased or changed during the firmware update. There could be two reasons: a disruption of the firmware procedure or the installation of a custom version of an unreliable software from an unreliable distributor (a separate functionality for IMEI in the version).

You first need to determine whether the erased code is real. To switch to dialing mode, enter *#06#. You will see the IMEI number, which you will need to look at the number of numbers written on the box of the device. If you can’t avoid the stench, this means that the IMEI is still worn out.

To check the IMEI code that is stored in the device’s memory, you need to enter *#06# in the dialing mode

In this case, you need to manually enter the code to renew the GSM connections. After this, you can call your phone number and get notifications.

How to enter IMEI manually

You can restore a deleted IMEI to the correct Android in at least two ways. The first one is located in the IMEI registered in the phone’s engineering menu.

On some phones, after pressing the specified button, the message “This command is not allowed in UserBuilld” may appear. There is nothing terrible about him. Just place the cursor after the “+” symbol in the entered row, add a space and stop the adjustment.

To update the IMEI for another SIM card (the same one), you need to close the engineering menu, repeat all the steps, then replace EGMR=1.7 with EGMR=1.10, and in the tabs enter IMEI for the other SIM card.

After this, you need to restart the device. IMEI codes will be rewritten, and the GSM module will be requested again.

Change or generate a new IMEI for help Chamelephon

Another method is to install IMEI through a special software. This is simpler, lower first, but still requires Root rights:

Video: how to change IMEI code

The device does not receive GSM traffic and does not connect to Wi-Fi.

If the phone does not show any GSM signal, this means that there is a problem with the IMEI code. How to solve this problem was described in the previous section.

Does not deny the IP address and does not identify the network

The problem of connecting to a Wi-Fi router can manifest itself in different ways. For example, the device does not connect to previous access points and constantly displays “IP address spoofing” or “Identification problem”. In another case, you just need to re-enter the password, scraps, swedish for everything, otherwise there will be damage when updating the device.

If you save the password, the password for the Wi-Fi access point will be damaged before flashing, you just need to enter it again

Once the “IP Address Removal” method is used, the most common problem will appear in the near future.

Connect to the access point, but do not interfere with the sides

The essence of the current solution to the problem with Wi-Fi connections: the device successfully connects to the required access point, otherwise the pages will not be connected. The reason must be checked by setting up the proxy server.

Another reason: the date was lost before the hour of updating. You can check it in the “Date and hour” section. This could have been changed based on the firmware release date.

Do not disable your home access point

If the home access point is not included in the list of available channels, this means that the new firmware has changed the frequency of communication on the mobile device. In this case you need to change the settings on the router. There are instructions to help you troubleshoot the problem.

This procedure is available only if we are talking about a homemade procedure, and not a huge one. If nothing worked, I had to reset the settings on the device. This will help you check for a system bug, which often appears when you merge the old version with a new one.

If the problem never appeared, the problem is in the firmware itself. It is necessary to sacrifice the updates and reset the device to the latest version or install custom firmware.

The device is glitchy and glitchy

Customers often note that after flashing the devices, they began to work even more, which is what they themselves wanted to ask for for an additional OS update. Clearing the cache and re-installing programs will not give any significant results. Effective decisions can be made to fix your phone or tablet or Hard Reset. You need to go to the menu “Adjustment” - “Backup copy and discount” - “Discard settings on your phone”.

It is important to ensure that after you send all the information: contacts, photos, videos, settings and programs. Therefore, you should create a backup copy of your data, if necessary, by checking the “Backup” and “Auto-Update” checkboxes. It is still necessary to reinstall the program to update parameters and data.

Click “Backup copy and discount” in phone settings Select the remaining item – “Zagalne skidannya” Press on “Discard phone”

An internal memory has emerged

After updating to a new version of the OS, the phone can recognize its internal memory. The obvious reason is a bug in the firmware version or inconsistency of the parameters in the phone and the custom firmware. The problem occurs when you reset the phone to factory settings (the Hard Reset procedure is described in the previous section of the article).

Flashing a phone or tablet is a job for those who are technically savvy. For the average customer, it will be easier to contact the service center and contact knowledgeable people. If you have just read the instructions, read a lot of information and still decided to install your own firmware, you need to check a few more points before carrying out this difficult procedure.

It is recommended to flash devices only to people familiar with the topic. This does not mean that a basic professional who strictly adheres to reliable instructions will be able to complete the task. However, there is a clear risk of problems occurring – both serious and not. There is no single panacea for all problems; skin problems have their own way of healing.

This post (manual or FAQ) is for people who are facing difficulties when updating or updating the software of their electronic device. All types of problems will be highlighted here, which are important to recheck your phone.

To be honest, in the entire hour that I have been working as an engineer, I have had a lot of such problems. I won’t be able to guess everything right away, but I’ll show you the bulk of these jambs that prevent the device from being flashed. Therefore, this manual will soon be updated and expanded.

You can also write your problems with the firmware in the comments - it’s still up in the air. First of all, before flashing the firmware, updating the firmware, rooting or other actions that can damage the device, follow the current rules.

1. Respect and “straight hands”

Every day I have to fix other people's mistakes that have made the device unproductive, because I blame the customer - I just wanted to update the firmware on my phone, but without bothering anyone or pressing any button in the process, or it doesn't matter after reading the instructions for the firmware, or having chosen the same version of the software - transforming your favorite gadget into a whole - a piece of plastic, made of metal.

Start with other people's favors. This means first pressing the START or DOWNLOAD button (there may be others), to find a suitable scheme for updating software, firmware, rooting, installing any other software. Do everything strictly according to the manual and do not change the settings of the stitcher, because you don’t know what you can get. Just be respectful.

2. Battery is faulty

Due to a faulty or discharged battery, the device may not be completely flashed, or it may turn on and not start the process itself. Such incidents occur quite often. The thought immediately subsides of the Fly IQ4404 Spark with its own battery. After fully charging the battery and putting the device on firmware, and for a number of minutes (in different ways), when the files are loaded, a message appears and the process slows down. And now we have “tseglinka”. But if you are not afraid of such zigzags, you will have to re-print the firmware.

I start from the beginning (the battery is fully charged, as you can see on the phone indicator) and after a while it starts again. Well, I think the “flash drive” died and I’m starting to get embarrassed, but I won’t give up. I set it to flash again, even without the battery, and I add the life block. The device is flashed. You can cross-read me and tell me that this is a quirk, but not a fact.

I have had more than one of these, and probably not ten. But for the sake of fairness, I’ll say that this is a serious fault, and in 99 hundreds of devices the firmware is flashed normally, as long as the battery is charged. Є technology that can be flashed without a battery. Or better yet, don’t risk it - don’t worry about charging the battery.

3. Problems with software

It turns out that the device does not want to be flashed through the software installed on the computer or laptop. Everything here is individual, but that’s the same thing.

For example, there are phone models that only “stitch” on WINDOWS XP PROFESSIONAL SP3, and the axis on the family is no longer designated or the flasher is not installed, which seems to be a problem. Also, since the operating system did not have the necessary components installed, the drivers were installed normally, but the smartphone was no longer registered in the system.

I had this problem through a limited edition Windows - WINDOWS XP HOME EDITION. I had to manually install everything, but it was still a hemorrhage. There are still a number of drives that will lead to breakdowns - broken archives of firmware and flashers, stupid versions of PZ from the leak - it happens that for the latest model of the phone a number of different revisions of motherboards are released, on which formation of microcircuits of processors and memory of various processors through this and There may be a number of firmwares, incorrect driver installation, or lack of administrator rights on the system.

If the firmware is incorrect, the boot (protected area) may crash and the device will stop showing signs of life - in 90 cases you will have to contact the service center, where there is a special programmer. So be very respectful, check it again several times.

4. Problems of “climbing”

If your device freezes, turns off by itself, does not connect, or the battery is quickly discharged during operation, then it is not a fact that problems will arise during the time of updating the software or removing the settings. Here everything seems to be much more complicated, and it is itself connected with the “leakage” of the gadget.

There are a number of typical jambs through which the phone may not be flashed - faulty or obstructed system connector, damaged cable for firmware or not entirely original, faulty USB or COM ports of the computer, faulty device in the middle, life-saving problems etc. P. but for a variety of reasons. If so, contact the service center for diagnostics.

Learn the basics before installing the firmware:

1. Fully charge the battery.
2. Check visually for any signs of trouble, problems with your PC or phone. There is a need for correction.
3. Check the originality and quality of the cable for the firmware.
4. Check for viruses and the entirety of all firmware, flashers, drivers, etc.
5. Also make sure you have installed the drivers, firmware and other necessary software components correctly.
6. Strictly follow the instructions when updating the software.

If you follow these simple rules, you will have much less hassle in the process of updating your software. Write in the comments your jambs about firmware. We will correct them at once. Good luck.

If the firmware is installed incorrectly, your phone may become inoperative, or as they call it on the Internet, it will become completely inoperable. This is where nutrition comes into play, so you can update Android on your own. Mostly, we recommend that you immediately contact the Service Center, but we recommend that you try all available “resuscitation” options right away. In this article we will describe all the options for creating a new functional smartphone from the “rounded” Android.

Last updated statistics - 03/29/2018

The legacy of recent firmware is visible

There are just a few jobs that will need to be done one by one. So as not to call Android a “device” or other names, the word “phone” will be used instead, so it’s easier and more meaningful.

Welcome to your phone/tablet via Recovery

If the phone is still turned off, turn it off. Then press the volume button and the volume button simultaneously. After this procedure, the smartphone will open sub-menu Recovery. Two options will be presented:

• Update the backup (this point is the main one before flashing the firmware, if the smartphone is flashed, then the backup will be updated). Select the early state of your system, then start the backup in Backup and Restore.
• Rozdil Install zip from sd card allows you to start the process of installing the firmware. At this point, indicate the exact route to the archive with the firmware. This option involves updating the system. Especially if your phone is in the process of installing important files.
  You may also be interested in this article.

Otherwise, when starting the firmware, Recovery may not be available. This situation can only be solved by using third-party programs. As a rule, this program TWRP Manager, ROM Manager or else Installer, which are the most popular in this country.

These programs allow you to select all the necessary components for a specific version of the operating system, automatically selecting the gadget and launching Recovery.

If any of these programs do not help you launch Recovery, you can try to find the program and run it on your current smartphone model.

Most of all, we discussed how to update your Android, since you still have a chance on a painless “Sunday”. Now let's look at what to do with it in the end, since the device will be on the surface of the seals and become a “whole”, because it does not function. If you think that this process is too complicated, then it’s not a good idea to run to the master and pay the master, try to earn it yourself for now. Let’s try to correct the situation independently in our own minds at home.

This instruction applies to updated phones and tablets manufactured by Samsung. If you have a different brand, you will need to select a different program or select an option from the following FlashTool. Is it important to pick up? Write to us in the comments - we will help you!

We can summarize a number of simple blood actions:

1. Install the remaining USB drivers for Samsung on the PC;
2. Please install the remaining version of the program Odin(https://4pda.ru/forum/index.php?showtopic=648344);
3. Further it will be necessary download the official(not the author's) firmware for your model;
4. We turn on the device, after which “-” is stamped on the volume key and “Dome”.

Show up ahead of time within an hour.

1. Press “+” on the volume key, after which the smartphone goes into Odin mode;
2. After this we connect it to the computer;
3. We launch Odin, then press the PDA, after which the file is named in it tar.md5 at katalozі, in which the firmware is modified;
4. Dali, pressing "Start", we launch the update program, after which the smartphone will be ready for use.

In such a simple way we turned the “head” at the exit point of a normal functioning structure.

1. We charge the phone to the maximum, so that it doesn’t turn off during the hour of renewal (don’t let it sit on charge for a couple of years);
2. We take a smartphone, which has transformed into a reference “target”;
3. Next we download the official firmware in FTF format;
4. Then you need to install the Flashtool program together with the firmware installation files on your computer;
5. If your antivirus program often interferes with other programs, it is best to turn it off for an hour so as not to interrupt the firmware process.

Here is the actual operation of updating Android via Flashtool:

• Vimikaemo Android;
• Place the FTF file with the firmware at the address: C:\Users\Im'yaKoristuvacha\.flashTool\firmwares;
• After starting, select the correct PC capacity (32 to 64);
• We press on the key with bliskavka logo;
• Turn on the “ mode Flashmode”;
• Next, a window will appear in which you select the firmware in this program;
• At the moment, when the firmware is ready, the program itself will notify you what time it is to connect to the PC;
• Initially, the program detects the device and then the Android update will begin. After everything has passed successfully, a sign will appear “ Flashing finished”;
• After this, you need to connect your smartphone to your computer and everything will work.

Check the driver installation guide, if you need to reinstall them, turn off the antivirus. And most importantly, turn the USB cable over and over.

The smartphone has been transformed entirely as a result of its failure, and not through a nearby firmware. How can you twist it yourself?

The Android operating system on each side of the device has its own systemic power, like software warehouses. If it happens that your device has become complete, then it is best to find out the instructions for your specific smartphone.

Most of the articles in the X-Mobile section are devoted to hacks and tweaks that allow you to remove root rights, modify the firmware, or replace it with a custom one. However, the reader is far from ready to give his smartphone such operations, I’m afraid that they will change the device completely or lead to instability in the robot. Today I will debunk these myths and show that it is not so difficult to turn your smartphone back to life even in a stalemate.

The city is in ruins

So, how can you “remake your smartphone completely” and what other pitfalls can tell you how to change the system and install custom firmware? What kind of glitches can occur and how can you kill a smartphone by reflashing it incorrectly? Will you use up the warranty forever and will you be able to turn your smartphone around? How effective custom firmware can fail the owner of a smartphone at the most unexpected moment and why not?

Myth 1. Incorrect flashing can damage your smartphone

You can crash your smartphone from the top, but it won't require flashing. The main problem that faces anyone who wants to reflash a smartphone is that when the firmware is installed, there may be a crash that will lead to its failure, and the smartphone will actually turn into one.

It’s all the same, but it’s worse on paper. To understand why, it is enough to understand how the process of flashing a smartphone works and what system components are affected. To remove the possibility of installing third-party firmware on your smartphone, you need to unlock the device (not on all versions), unroot and install a custom update console (ClockworkMod or TWRP), and then install the firmware with some kind of digital signature.

The update console is saved in a separate section of the internal NAND memory and is in no way connected with the installed operating system. After installing a modified version of the console, you will be able to flash custom firmware or another OS (Firefox OS, for example). If the firmware becomes damaged before the firmware is installed, the smartphone will not appear in the recovery mode, the update console will be lost in place, and everything that needs to be done will need to be installed again in recovery and install the firmware.

In addition, any custom update console has a backup/update function, which allows you to create a backup copy of the main firmware and update it in the same view (with all the additional shtuvannyami and danimi) at that point, because things are wrong. In fact, the smartphone can be turned to the cob.

You can ask: what will happen when the update console is installed? Nothing, in which case the situation will turn out to be bad if the operating system itself is lost in place, and the console turns out to be wasted. To get started with it, you just need to flash the recovery again directly from Android.

Hypothetically, it is possible to identify the situation if both the firmware and the console are updated (you want to work hard), but in this case you will forever lose the original device that was flashed into the permanent memory of the smartphone.

Note: it’s impossible to drive a smartphone and install third-party firmware through a custom update console. On the spot, you will forever lose either recovery or the first vantage point.

Myth 2. Custom firmware is unreliable

Warranty firmware firmware. In the vastness of the world's wide web, you can find a large number of Android compilations with any taste and color, and most of them are truly trash, which can lead to instability in the smartphone and the loss of some functionality. The first thing to remember is that on the right the motherboard is equipped with serious custom firmware, which is developed by great teams of advanced developers. First of all, we have CyanogenMod, Paranoid Android, AOKP, OmniROM and MIUI.

Friend. There are two types of firmware: officially supported and ported by third-party vendors. The same CyanogenMod, for example, has an official version for the Nexus 4 smartphone, but there is no such version for the Motorola Defy. The prote for Defy is an unofficial port of CyanogenMod 11 as a package with Quarx. Their importance lies in the fact that the CyanogenMod team is the first to provide support and correct efficiency, as well as another - Quarx especially. The official versions of the firmware are purely practical, and the correctness of the other work is left to a third-party vendor.

That's the third. Stable and updated firmware versions are available. Stable versions of CyanogenMod have the index M (CyanogenMod 11.0 M7, for example). This firmware version is designed to avoid bugs. The version that is released (in the case of CyanogenMod during daily compilations) may contain bugs and is not recommended for everyday use.

Note: if you install a stable official version of normal firmware on your smartphone, the risk of encountering bugs is minimal. Everything else is for experimenters.

Myth 3. Software that requires root rights built on a smartphone

Theoretically, if you have root rights, you can do anything with the smartphone’s firmware, including completely erasing it. Therefore, with such software you need to be very careful. The software that we review on the pages of the magazine is completely safe and tested on a damp skin. In addition, for the entire hour the rise of smartphones on Android (and starting with version 1.5) I once in a while without being affected by the situation, if the software is driven into the smartphone using root support.

The software, which is available everywhere through Google Play, completely corresponds to the stated characteristics, and, if it leads to the goal, or by removing the backdoor from the smartphone, the store will not waste time. In any case, it is important to follow the rules of “trust before disbelieving” and carefully read the instructions from the root app.

Myth 4. Root rights to disable a smartphone will be spilled for viruses

Let's make it possible for smartphone viruses to remove not root rights, but bugs, which are used to remove them. Rooting tools and viruses can exploit the same Android components to take away root rights, but the very fact that root is visible on the device does not change anything. If you write the virus correctly, you cannot obtain the right in a standard way, seeing its presence, the fatigue of the virus is accelerated by the same spillover in order to eliminate its secrets.

Moreover, if you are root, you will not be able to install the latest version of Android (like custom firmware), in which the bugs have already been fixed. It’s also important to remember that most custom firmwares allow you to enable root or create additional lists of add-ons that can be used to change rights.

Myth 5. A rooted smartphone can be damaged

Software, signs for the Root Odrimann, Retri Chotiri Prosti Rechi: Launch of EXECOLOTE, Yaky Permanent ROMAT ROOT ROOT, MONTEM RODEL /SYSTEM in the recording mode, Catalog /System /XBIN Binarnik SU, Non -Chistyan Right Rights Root Nadally. Program SuperSU or SuperUser, which allows you to control every time, if any program requests root rights for additional su.

These steps cannot lead to a malfunction or crash the smartphone. The only thing that can happen is the exploitation of the segmentation and the smartphone will be re-engaged, after which you can continue to operate normally.

Myth 6. By unrooting and installing custom firmware, I will void the warranty

The warranty is expired not by the fact of unrooting, but through its identification by the service center. For most devices, you can remove root rights using the additional Universal Unroot program, or by reinstalling the stock firmware using additional official programs from the driver.

There are two faults with this rule. The first is the Knox system, installed on new Samsung smartphones and tablets, such as Galaxy S4, S5, Note 3 and Note 10.1. Knox will provide advanced Android security, responding to any firmware modifications and installation of third-party kernels and firmware. In this case, when the current data is collected, the system installs a trigger that confirms the fact of modification. The trigger is implemented in hardware (eFuse chip), so you won’t be able to throw it off in the cob position. On the other hand, it is not entirely clear how the service center should repair the device on this platform. Other: eFuse installations on many other devices (for example, smartphones from LG), and it also allows you to accurately determine the rooting or reflash the smartphone.

If we talk about custom firmware, then everything is more complex. Therefore, the flashing operation involves unlocking the device, and can be done using special exploits, or using the additional web service of the smartphone manufacturer. In any case of unlocking, you can definitely tell that the smartphone is far from white.

On some smartphones, it is possible to lock your account back, so that you can properly recognize it, and also keep in mind that locking your account, which means everything, will change the status to Re-locked, and not Locked, as it was originally (as it is on HTC smartphones, for example). The only culprits here are the smartphones and tablets of the Nexus line, which can be blocked and unblocked in three clicks without any dances with a tambourine, and neither of them can be bothered with anything.

INFO

For Linux, ADB and Fastboot can be installed directly under the Android SDK. On Ubuntu: sudo apt-get install android-tools-fastboot. For Fedora: sudo yum install android-tools.

To prevent the Knox system from respecting the root program, you can use the following command from the terminal: su pm disable com.sec.knox.seandroid.

Unrooting and flashing a smartphone are absolutely safe operations that cannot be described on a smartphone for technical reasons. One culprit - try to hack the cob zavantazhuvach with the method of unblocking it. This type can be equipped with an eFuse chip (like the one on a smartphone) and block the ability to turn on the smartphone.

Today, today's smartphone manufacturers either choose not to block the ability to turn on a smartphone with a hacked locker (by setting a trigger to confirm the fact of such an action, how to work Knox), or implement a special web service that allows Painlessly unlock your smartphone without voiding the warranty , which ranks as a necessity for risk-taking, lamayuchi zavantazhuvach.

Problems that may arise during the flashing process

Now let's talk about what problems can arise when rooting is removed and flashing and how to deal with them.

Scenario one: after a recent flashing, the smartphone is no longer attractive

Not long after, flashing the firmware could be a problem with some officials: the battery ran out, and the firmware was only half filled, the firmware turned out to be faulty or intended for a different smartphone model. I'm sorry, there's simply no place on the smartphone that you can install when trying to install the latest version of Android on a smartphone that's three years old.

All these problems appear either in the repeated downloads of the smartphone to the original logo of the printer, or in the so-called boot-loop, when the animation is required to spin on the screen for five to ten minutes. There may be problems with the screen (different colors) and non-functional touch screen, which may also cause the smartphone to malfunction.

In all these cases, it is enough to do one simple thing: turn on the smartphone by pressing the recovery button, then turn it on using the power button (some smartphones use a different combination), and then use recovery , reinstall the firmware (Install zip from sdcard -> Chooze zip from sdcard) or update the backup (Backup and restore -> Restore). Everything is easy and simple.

The scenario is different: the firmware is working, but recovery is not available

This may happen after a recent installation or console update. The problem is that after restarting the smartphone and pressing the change button, a black screen appears, after which the smartphone either drops or hangs.

Solving this problem is not easy, but it is even simpler. You can install the update console on the vast majority of smartphones using the additional programs TWRP Manager, ROM Manager or ROM Installer. They themselves determine the model of the smartphone, download and flash the required recovery, without having to re-install it. Since there is no way to restore the console, you just need to know the instructions in Merezha for installing recovery on your device.

Third scenario: neither firmware nor recovery is available

Honestly speaking, it is less important to recognize such a scenario, but, as practice confirms, it is completely real. There are two ways to get out of this situation: use the fastboot button to upload recovery to your smartphone, or use the quickboot tool to install the firmware. We’ll look at another method in the next section, and I’ll talk about fastboot here.

Fastboot is a tool that works directly with the original download device and allows you to upload firmware, recovery and download unlock to your smartphone (for devices from the Nexus line). The fastboot support is available on many smartphones and tablets, as well as devices that block the ability of your browser. So you will have to consult the Internet for information about this.

To gain access to fastboot, you will need the Android SDK drivers. Once they are installed, open the command line, go to the SDK installation directory, then to the platform-tools directory, remove the smartphone, turn it on using the volume buttons and connect it via an additional USB cable to the PC. Then you need to find the recovery image in the .img format for your device and enter the command:

$ fastboot flash recovery image.img

Or you can download your smartphone and install recovery without any actual installation:

$ fastboot boot image.img

So you can flash it yourself official Firmware update:

$fastboot update update file.zip

You can find a suitable recovery for your device either on the TWRP website or on the XDA-Developers forums and w3bsit3-dns.com.

We turn the smartphone to the cob

In this section I will learn about ways to turn your smartphone back to a clean drain, which is not the case. These instructions can be followed both for unlocking the smartphone and for removing traces of rooting and flashing. Unfortunately, I can’t tell you about all possible models, so I’m focusing on a few of the most popular flagships: Nexus 5 (which I call the control copy), Galaxy S5, LG G2 and Sony Xperia Z2.

Nexus 5 and other Google phones

It’s easier to turn the Nexus line device to its full size than any other smartphone or tablet. In truth, it’s so simple that there’s nothing to tell about it here. In fact, all that needs to be done is to install the ADB/fastboot drivers (in Linux there is no need), download the archive with the firmware and run the script. Step by step the whole operation looks like this:

1. zvidsi.
2. It is necessary to install the Android SDK.
3. We collect archives with firmware for the required device from the Google website.
4. The device is wet, wet with pressed volume buttons (both) and connected with an additional USB cable.
5. We unpack the archives with the firmware and run the flash-all.bat (Windows) or flash-all.sh (Linux) script and check for the completion of the operation.
6. We launch the command line, go to the directory with the Android SDK, go to platfrom-tools and select the fastboot oem lock command to lock the device.

For those who don’t want to run the script, here is a list of commands:

Fastboot flash bootloader bootloader-IM-DEVICE-VERSION.img fastboot reboot-bootloader fastboot flash radio radio-IM-DEVICE-VERSION. recovery recovery.img fastboot flash boot boot.img fastboot erase cache fastboot flash cache cache.img

Galaxy S5

With the Galaxy S5 smartphone, everything is more compact, but it’s easy to access. When will you need the Samsung Odin program, which can also be used to update your smartphone's firmware. Sequence of actions:

1. Please install the latest version of Samsung USB drivers.
2. We download and install the remaining version of Odin.
3. We go to the website samfirmware.com, search for the SM-G900F model, find the firmware with the Russia icon, download it and unpack it.
4. We shake the smartphone and press the pressed buttons to change the volume and “Dodom”, wait five seconds until the next notification appears.
5. Press the increase volume button to switch the smartphone to Odin mode.
6. We connect the smartphone using an additional USB cable.
7. Launch Odin, press the PDA button and select the file with the tar.md5 extension in the middle of the directory with the unpacked firmware.
8. We press the Start button in Odin and wait until the firmware process is completed.

As I already said, this operation will turn the smartphone to the ground, but not throw off the trigger, installed by the Knox system (as it was standard firmware). Therefore, the service center can be used for repairs.

LG G2

Updating the LG G2 to factory standard also does not cause any particular problems. The number of steps in this process is even greater, but in itself they do not require special preparation and knowledge. So, what to do, turn the factory firmware on the G2:

1. Please install ADB Driver Installer from here.
2. The official firmware (Europe Open 32G or Europe Open) is available.
3. It is important to install the LG Mobile Support Tool, as well as FlashTool (goo.gl/NE26IQ).
4. We wring the smartphone, press the increase button and insert the USB cable.
5. We unzip the FlashTool archive and launch the UpTestEX.exe file.
6. In the window, select Select Type -> 3GQCT, Phone Mode -> DIAG, in the Select KDZ file option, select the firmware downloaded in another section.
7. Press the CSE Flash button at the bottom of the screen.
8. At the window press Start.
9. At the next window, select the edge and press Ok.
10. We check for the completion of the firmware, and then the smartphone is connected and connected.

That's all. Please note that, since we are connected to Samsung, the smartphone still has Rooted status and cannot be corrected.

Sony Xperia Z2

Now let's talk about how to restore the Sony Xperia Z2 smartphone to factory condition. As in the first two cases, for which you need stock firmware and an official firmware utility. You launch the utility on your PC, connect your smartphone with an additional USB cable and start the update process. Pokrokovo everything looks like this:

1. Please install ADB Driver Installer from here.
2. We reset the smartphone to factory settings.
3. It is necessary to install the Flash Tool from the official Sony website and install the remaining firmware.
4. Copy the firmware file to the directory C:/Flashtool/Firmwares.
5. The smartphone gets wet and gets stuck with the pressed keys, changing the thickness and “Dodoma”.
6. We connect the smartphone to the PC using an additional USB cable and launch the Flash Tool.
7. Press the button with the blink icon in the Flash Tool. In the window, select Flashmode, then click on the firmware in the list.

WARNING

In many smartphones, the zvantazhuvach will not allow you to update everything.

In 90% of cases, the mobile phone unlock will result in the deletion of all data from the smartphone, including the memory card.

Visnovki

Flashing a smartphone, and more importantly, removing root access, is not at all as scary and unsafe an operation as it might seem at first glance. As long as you do everything correctly and don’t go into the tools that unlock the lock of your smartphone, bypassing the driver’s tools, you won’t be able to hack your smartphone. So, in some situations you have to tinker with everything to get everything back on track, or better yet, have to deal with a locked smartphone that doesn’t allow you to make half of these speeches, so how can you give up full control over the device? I'm sorry, reinstalling Windows on a PC does not hurt anyone.

There are no reasons why you can access through any device on the Android platform:

1. System flashing is incorrect.

2. I recently tried to create a ROOT law enforcement.

3. Unauthorized actions to change system data of the operating system and many others.

It means that most of these types of problems can be solved by the initial flashing method, especially if your Android does not turn on at all, which is what we are talking about in today’s statistics.

Let's get to the top of the problem

This problem is absolutely clear, but only in that case, if the owner doesn’t care. To switch to its functionality, you must press the power key - the display of the device may show any reaction you want. This may be a robot, but sometimes it is just a sign of a hail. The appearance of such icons suggests that the whole problem is in the operating system itself, which means that in 95% of cases there is nothing critical about it.

Such failures have been noted if the screen of the device does not respond at all to the power-on test. Then you just need to connect the gadget to the computer and try pressing the “Increase” button or pressing the combination of the “Increase” and “Vol-” buttons. If the PC is ready to connect a new device, then there is still a good chance of flashing Android.

Android firmware for additional software

One of the most basic methods is to improve the functionality of a smartphone or tablet through the device’s software. Ale Varto means that not all brands have such functionality. For example, LG has introduced this method.

To update you need:

1. Install the program from the vibrator on your computer. For LG devices, it is called the Mobile Support Tool.
2. With this software, you need to get a driver for your gadget. For this purpose, the program has a special tab “Install USB Driver”. All you need to do is select your model from the registered list and press the confirm button.
3. Next, you need to connect your smartphone (tablet) to the computer using a standard cord and press the “Power Up” button or the combination “Power Up” + “Vol-”. The window that appears is responsible for the connection of the device.
4. In the program itself, you need to go to the “Additional capabilities” tab, which is located on the right side, and click on the item “Update after an update failure.” Then follow the instructions that appeared.

Firmware for additional installation of custom Recovery

This method allows you to flash the firmware of your Android, which includes access to the Recovery function. To use these functions in the menu, you need to press the combination of the “Power” and “Vol-” keys.

If this mode is activated, and you access approximately the same menu items as shown in the picture, you need to do the following:

1. Download the required firmware file for a specific model from the separate ZIP file. It’s easy to know - a lot of publishers on their official websites give such files to clients. There are also a lot of third-party sites with such files, you just need to enter a search string in the search box.
2. Transfer the software downloads from your computer to the Android memory card and insert it into the slot. If the device does not have such a slot, then this method of flashing the firmware is not suitable.
3. Next, enter the Recovery mode by pressing the combination of the “Increase” and “Vol-” keys.
4. Go to the "wipe data" tab, to the "factory reset" directory, to clear the memory of corrupted files.
5. Then you need to click on the “Install zip from card” item, select the previously downloaded file on the gadget’s memory card and confirm the click on the “So” button.
6. Wait until the operation is complete and restart the device by clicking on the “Reboot system” item.

Firmware via custom software for Windows

If the device does not boot after flashing the firmware, you can also reflash one of the unofficial programs for your computer. For a skin brand, the software and procedures may vary, but most of them are very similar:

Vikonannya firmware process:

1. It is necessary to install the required firmware on your computer. As you understand, the gadget is out of stock.
2. Next, you will need to install the firmware for a specific device model.
3. Launch the installed program.
4. Connect the device to the PC via a standard cable and press the combination of the “Power” and “Vol-” buttons.
5. Through the program, select the file from the firmware and press the “Launch” button.
6. The process is completed.
7. Re-engineer the gadget.
