Hi everyone, last night I accepted AT&T's suggestion of updating my software, and now the phone has been for 8 hours backing up my data (it stopped at 8% in social feeds and hasn't moved) and of course I cannot use it, it wouldn't let me go back to main menu or any app. Don't know what to do, I already shut it down, took the battery off, it seems stopped there and honestly I don't mind not having this update done, I just want to be able to use the phone. What can I do?
