I have an 2018 model iPad, just over one year old. It has iOS 13.3 beta on it (although I haven’t actually been doing any dev on this device). It was fine until a few days ago. I was in the YouTube app, hit the subscribe button, and the screen froze for a few seconds then restarted. I just got the ‘restore’ screen, telling me to connect to a Mac and restore. So, I did that, iMac running Catalina. The finder takes some time downloading and then says ‘preparing to restore’, but it never actually does the restore. I waited a night and a day (just over 24 hrs). The Mac store ‘genius’, didn’t actually do anything beyond what I had already done (doing DFU restore, etc).
So, as it is two weeks out of warranty, I purchased PhoneRescue for iOS earlier today. Connected, did the dowload, at it has said ‘Restoring iPad software, restoring 0%’ for the last 3 hours. It doesn’t look like this will succeed. I’m wondering if it is because the iOS version is probably later than the released version that it will have downloaded, and I should try again after the next software release, or whether this application cannot solve the problem.
