Apple Stops Signing iOS 12.1.1 Beta 3, Downgrade for Jailbreak No Longer Possible

Apple has stopped signing iOS 12.1.1 beta 3 meaning that users can no longer downgrade to that firmware version for jailbreak.

Pwn20wnd, a key developer behind the unc0ver jailbreak, made the announcement on Twitter today.


iOS 12.1.1~b3 was unsigned by Apple! ;(

1conan confirms that the firmware is not currently being signed for any iOS device.

The unc0ver jailbreak will still work for devices running iOS 12 - iOS 12.1.2 but if you've updated to a newer firmware version you will not be able to downgrade for a jailbreak.
