I updated to IOS 9.3 before I wen to bed-what was I thinking? I have ipad 2 GSM. I have tried all the fixes posted, even resorted to the restore, after trying to downgrade to the last IOM update didn’t work either. No surprise, that didn’t even work. I have I have spent three days trying every possible method countless times. Apple had better have an update posted soon to resolve this. I never received a warning to “clean-up” my iPad first, for additional space, or you should probably back up before updating…Lesson learned deep into my personal hard drive.
