Hi there, users As I am a new user on the resource. Plz understand my curiousity. I have just updated my new Ipad Air, presently, and here I think I felt like more comfortable while using an old IOS 8.4. As I see the Apple's policy now, they won't let people downgrade for the firmwares, they stopped signing. Now the question is , any chance to bypass this prohibition? I would be really glad to hear the apple hackers' success in finding new vulnerability at this point. There was time earlier, I used to have iphone 3gs, there one could use tools like tinyumbrella to simulate apple vefivication services for the firmware signing... Any new step at this move on these days?
