So I went to unlock my iPad, running iOS 5 beta 5, and it was at the setup screen as if it just erased everything and restored itself. I was just using my iPad like five minutes before though. So then when I tried to set it up (in hopes I could go back and restore from a back up) it wouldn't activate. I then tried to restore from a backup but no luck, I get errors that the software expired. Then when I try to restore just the stock iOS 5 beta 5 software, it gives me errors (I got error 20 and error 3914 or something like that). It seems like everything I try to get back to iOS 5 just won't work. I'm running 4.3.5 right now, any suggestions on what to do?
