Apple stops signing iOS 14.4.2, preventing downgrades from newer firmware

After officially launching the highly anticipated iOS & iPadOS 14.5 update a week ago with support for Face ID authentication while wearing a mask and 5G connectivity whilst utilizing dual SIM mode among other things, it should come as no surprise to anyone that nearly one week later the Cupertino-based company is pulling the plug on the previous iOS & iPadOS version — 14.4.2.

Apple’s decision to stop signing iOS & iPadOS 14.4.2 means that iPhone and iPad users will be unable to downgrade to this particular version of Apple’s mobile operating systems under most circumstances, with the lone exception being that users have their .shsh2 blobs saved from a time when that firmware was being signed.
