Apple Stops Signing iOS 10.2

Following the release of iOS 10.2.1, Apple has stopped signing iOS 10.2 firmware. That means that you can no longer upgrade, downgrade, or restore to that firmware, either over-the-air or through iTunes. You also can no longer save blobs for iOS 10.2 through any tool.

Since the release of iOS 10.2.1 last Monday jailbreakers everywhere had been racing the clock to either save blobs for, or restore to, iOS 10.2, before Apple closed the door on them forever. In the end, they were given only seven days in which to make their move. Hopefully, many users were able to follow our guide in time, advising them to save their blobs and in some cases, to restore to iOS 10.2.

The iOS 10.2 closing window is also an important news for those who are already on iOS 10.2 and want to try yalu jailbreak beta on their devices. Since iOS 10.2 is no longer being signed, you will no longer be able to restore your device to same iOS version in case your device gets in an unending bootloop or any other error appears on your device during the jailbreak process.

Those who have their blobs safe but did not restore to iOS 10.2 in time can now rest relatively easy, knowing that in theory tihmstar’s tool Prometheus will allow them to upgrade to iOS 10.2 at a later date.

Anyone who already made the jump to iOS 10.2, well done! Be cautious with your jailbreak now, and careful with the tweaks you install, until the jailbreak has reached a final build and all tweaks are updated. A mistake now could mean a restore to iOS 10.2.1.

Apple has already released the first beta of iOS 10.3 which comes with a number of new features including Find My AirPods, user security section in Settings, APFS, and more. The final version of the OS is expected to be released in March.
