@drama_binny it "supports" all 64-bit devices, but if the device you're restoring supports 16+ and doesn't have a signed 15.x or below version then it's useless
iOS 15.3 RC is *STILL SIGNED*, and a new FutureRestore beta has been pushed by @Cryptiiiic that will allow you to restore using the 15.3 RC SEP/Baseband. If youβve put off updating to 15.1(.1), this is your last chance.
Your jailbreaks will be missed.
But I would just like to remind everyone that CS leaving will not affect Procursus at all. We look forward to supporting the next generation of jailbreak developers in providing the best possible experience for their users.
