Is iOS 9.1 downgrade possible? Some users didn’t have enough time to learn all the minor changes offered by 9.1 firmware and thought they would get back to iOS 9.0.2 later on to become jailbroken. The latest news state you don’t have a chance to turn back time and downgrade form iOS 9.1 to 9.0.2 any more. If you visit the popular site ‘ipsw.me’ that shows the real-time signing status for different Apple operating systems for iPhone and iPad you’ll notice that there is no green checkmark [instead you will notice the red warning sign]. iOS 9.1 downgrade to 9.0.2 is impossible because the Cupertino-based giant doesn’t sign the previous firmware version. Why do iOS users downgrade? One of the reasons is the possibility of jailbreaking older firmware. Apple often kills [patches] the exploits discovered and used by hackers as soon as it presents a new upgrade. This happened when iOS 9.1 was officially released [you can download 9.1 ipsw file if you wish to install this version]. Pangu team found a way to untether 9.0.2 firmware and Apple quickly patched the holes in its code and launched 9.1 that is non-jailbreakable. Were you lucky to downgrade when it was still possible or not? A lot of users who installed 9.1 and discovered no major improvements and enhancements hurried to get back to 9.0.2. Still some users preferred staying on the iOS 9.1 and they can no longer use Pangu unless the team presents another solution that supports the newer version of iPhone / iPad mobile OS. Apple, developers and public testers are already working on the iOS 9.2 version. This is the next upgrade that should arrive in the future. It might be presented this November since this update won’t be major as well.
