David has a first generation iPad Mini and it won't clear out an old Apple ID, even after doing a reset. Leo says that the new version of iOS requires users to verify the old Apple ID and password to prevent theft of a device and then just wiping it. Leo says one thing that David can try is a DFU reset.
The chatroom says he could try and contact Apple and explain the tale and see if they'll remote clear it. He should try going to Apple.com/iForgot as well. Leo understands why Apple has done this, but he thinks it's going too far.
