An unknown error occurred
My iPad was switched off for few months and I turned it on few weeks ago. It showed that it need an update so I tried to do that but in the middle of it I got an information that an unknown error occurred and that I need to log in to apple I'd, when I logged in it says that I have a wrong password (it was a good password), I reset my apple id password on my laptop and waited 2 weeks for my account reset. I changed a password, login on computer as usual and when I try to log in on my iPad I got a message 'an unknown error occurred', so I tried to reset the whole iPad but I can't because i need to log in to apple Id first and ipad would not let me do it. What can i do?
