BootROM exploits are way too valuable to be released publicly now. This is just a concept and will probably never be realized, ever. Users can then run incompatible apps on iOS 11. Once a BootROM exploit goes public, hackers can flash a custom ROM with the requisite 32-bit library. This scenario obviously rules out the tweak route because it simply is not powerful enough for this sort of upward compatibility. We can still have support for legacy apps provided we get something really powerful in the future. Nothing is impossible in the iOS ecosystem thanks to the relentless efforts of jailbreak developers. Can we ever get 32-bit support on iOS 11?
IOS 11 now only contains ARM64_dyld_cachem, which can run 64-bit applications.
Therefore, users can only use apps that can run on 64-bit architecture.Īccording to security researcher Billy Ellis, the “dyld_shared_cache_armv7” file responsible for running such applications is no longer present in this firmware. You can test this out yourself by installing LowerInstall Cydia tweak on your jailbreak.Īpple totally wiped off anything remotely 32-bit from the kernel.
However, a few experienced developers looked into the app support issue and confirmed that this wasn’t the case. Some users erroneously thought that the reason behind this was restrictions put in place by Apple. This firmware can no longer run applications like Flappy Bird that require the aging 32-bit architecture.
