It is your responsibility to protect your SHSH-certificate (digital signature, unique for a skin device).

Now it's a blazing tide. As a rule, it is possible to download the older version of the firmware:

a) even though the front firmware is still up to date. For example, at once the whole world is testing iOS 9 Public Beta. The official version of iOS 9 is coming of autumn. And that means that until this moment, it is possible for a person to flash their attachments to the current official iOS 8.4.

b) as a new official firmware has been released. For example, after the official release of iOS 9, it may take 1 to 7 days (maybe 3 more days), so you can change your mind and ask for a solution. If you mit Apple raptom, you stop signing old firmware and then you find it impossible or there are no difficulties.

Krok 2 Enabled the function: "Know iPad, iPhone or iPod" (deposit in your outbuilding). Customization->iCloud.

If not, then iTunes will not let you download the firmware. After flashing, do not forget to turn on the option.

Krok 2 Connected to the computer via a cord. We go to iTunes and select a device. Click on the "View" button and press it with the Alt-Option key (OS X) or Shift (Windows) pressed forward.

In the new window, I select the firmware. Let's keep at the vіknі tysnemo "Vіdnoviti" and start the process of renewal / vindication.
