Following the release of iOS 14.0.1 last week, Apple stopped signing iOS 14. If you have upgraded to iOS 14.0.1, you will no longer be able to downgrade to iOS 14.0.
iOS 14.0 was released in September after a three-month beta test. The update has changed the design of the home screen, the application library and other improvements. 30% of Apple devices now run iOS 14, up 10% from iOS 13 last year.
IOS 14.0.1 was released last week with bug fixes. Among them was a bug that reset applications by default after a reboot. Also fixed problems with Wi-Fi and mail.
Users often revert to older versions of iOS to install a jailbreak in the future. The checkra1n tool already supports iOS 14, but only on older devices.
Sometimes a rollback is needed for those who encountered a serious bug in the update. If you have problems in iOS 14.0.1, you will have to wait for the next update, because a rollback can no longer be done.
At the moment, rollback is only possible from iOS 14.2 beta to iOS 14.0.1.
