IOS update installed passcode and now I'm locked out of my ipad
Ok, heres the issue. My mom gave me her old Ipad and when I updated to the new IOS it installed a passcode on to the Ipad where there had not been one installed before the update. I've tried everything to try and unlock it but nothing has worked. I've put the Ipad into recovery mode and tried to recover it by syncing into itunes, and that seems that it might work. But my recovery time is 3 hours and before it can finish the Ipad has rebooted into the normal lock screen. I've tried restoring the back up but a message keeps popping up that I need to go into the icloud settings on the ipad and turn off the find my ipad feature. I can't do this beacuse I'm locked out of the ipad. I've tried everything short of taking it to an apple store and seeing if they can do anything about it, however I really would like to keep from driving an hour and a half to the nearest apple store. Please does anybody out there have any idea on how to fix this problem.
