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.
