Following the launch of iOS 16.0.2 last Thursday, Apple has stopped signing iOS 16 and iOS 16.0.1, the 2 antecedently out there versions that came enter mid-September. Since the two versions are no longer being signed, it's impossible to downgrade to those versions of iOS after installing iOS 16.0.2. Apple habitually stops signing older versions of software updates after new releases are set out so as to encourage customers to stay their operating systems up to date, thus it is common that iOS 16 and iOS 16.0.1 are no longer being signed.

Apple released iOS 16 to the overall public on Sept 12 following many months of beta testing. Key new options embody an extremely customizable Lock Screen, the ability to temporarily edit or unsend iMessages, enhancements to Focus modes, and more. The free software update is compatible with the iPhone 8 and newer. Apple then released iOS 16.0.1 as a day-one update for the iPhone 14 models to fix bugs as well as a problem with activation and migration throughout setup, a problem that might cause photos to look soft when zooming in in landscape orientation on iPhone 14 pro-Max, and a bug that might cause enterprise single sign-on apps to fail to authenticate. Though it's not potential to downgrade to the sooner versions of iOS made public above, users can still revert to iOS 15 by connecting to a mac or PC, due to a security fix that Apple issued alongside iOS 16 within the form of iOS 15.7.
