I restarted my iPad that had a 4 digit passcode. When I opened it up again, it asked for a 6 digit passcode. I never set a 6 digit one and now can't get in! I don't want to delete my iPad. I have also already tried 123456 and 000000 and putting random 0s in my old passcode. It is very frustrating! Please help!
