My daughter gave me her ipad 2 she done a hard reset and deleted it from her account I have tried registering it to my account says it does not recognize it. I have it twice
iPad 2, iOS 6.0.1, Will not register to my account
Wipe iPhone/iPad/iPod touch clean
There are a few steps to do:
Switch off iMessage in Settings > Messages
Switch off FaceTime in Settings > FaceTime (iPod touch 4th Generation or later, iPhone 4 or later and iPad 2 or later)
Delete iCloud in Settings > iCloud > Delete Account
Finally Settings > General > Reset > Erase All Content and Settings.
Un-register your device: https://supportprofile.apple.com
Now sign in your Apple UD in the above options.
You are probably typing one of the characters in the serial number wrong.
For example the letter "oh" instead of the number zero.
