Apple has stopped signing iOS 14.5.1, preventing users from being able to downgrade or
restore to that firmware version.
Currently, Apple's latest firmware is iOS 14.6. If you accidentally update or restore, you'll
find yourself on that version. Developers have been seeded with iOS 14.7 beta.
Those interested in jailbreaking are typically advised to stay on the lowest firmware possible;
however, the checkra1n jailbreak makes it possible to jailbreak most devices between the
iPhone 5s and iPhone X on any firmware version above iOS 12.3. The unc0ver jailbreak and
Taurine jailbreak support all devices running iOS 14 - 14.3.
