iOS 14.4.2

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.

Apple closes signing window for iOS & iPadOS 14.4.1, halting downgrades

Apple released iOS & iPadOS 14.4.2 last Friday alongside iOS 12.5.2 for older devices that don’t support iOS & iPadOS 14 in an effort to remedy a WebKit-based security vulnerability that the company had knowledge of being actively exploited in the wild to maliciously impact its user base.

Given the amount of time that has passed since the release of those updates, we’re unsurprised to learn that Apple has officially stopped signing iOS & iPadOS 14.4.1 this evening. It’s a move on the company’s part that bars the majority end users from voluntarily downgrading their handset’s firmware to the previous version.
