Apple blocks downgrades to jailbreakable firmware by unsigning iOS & iPadOS 13.5

Apple this evening stopped signing iOS & iPadOS 13.5, a move on the Cupertino-based company’s behalf that essentially prevents iPhone and iPad users from installing this particular version of its firmware whether downgrading from a newer version of the mobile operating system or upgrading from an earlier version.

The move comes approximately one week after Apple released iOS & iPadOS 13.5.1 to the general public specifically with the intention of patching the 0-day kernel vulnerability that Pwn20wnd implemented into the unc0ver jailbreak to add support for iOS & iPadOS 13.5, the latest version of Apple’s mobile operating system at the time.
