If you’re using an iPhone XS or newer, up to and including the iPhone 11 Pro, then this change would impact you as the checkra1n jailbreak doesn’t support these handsets. The fact that this was a beta firmware probably exacerbated Apple’s unsigning decision, as the company tends to disapprove of when users install beta releases for any reason besides testing them to report bugs to be patched in final releases.Īs for who this change impacts, that’s a very subjective situation…Īnyone using a handset as old as the iPhone 5s or as new as the iPhone X can easily jailbreak with checkra1n regardless of the firmware version they’re using since this jailbreak uses a hardware-based bootrom exploit called checkm8 that can’t be patched by Apple. Surprising? No not really especially given the fact that Apple has been rather quick in recent memory to cease signing versions of iOS and iPadOS that can be hacked for the sake of user enjoyment.
The news was first pointed out by an avid jailbreaker on /r/jailbreak late last night, and further reinforced by several commenters who claimed they began receiving errors while attempting to install iOS 13.5.5 beta 1 on their handsets: Apple appears to have stopped signing iOS & iPadOS 13.5.5 beta 1 as of last night, effectively and once again preventing iPhone and iPad users from installing a jailbreakable firmware for the second time in the same week. Hacker and unc0ver lead developer Pwn20wnd quickly responded to the act this week by releasing unc0ver v5.2.0 with support for iOS & iPadOS 13.5.5 beta 1, providing jailbreak hopefuls with a second chance to upgrade to jailbreakable firmware.īut as it would seem, this was a short-lived hoorah.
Apple unsigned iOS & iPadOS 13.5 on Monday in a move intended to prevent downgrades to a publicly available jailbreakable firmware version.
