Activation Lock ****
I'm trying to help my father law get his iPad working again. He couldn't remember his passcode so I had to reset the device. When I reset the device it gives me the activation lock username/password. His wife and him have iCloud accounts but neither Apple ID/password works. I've been able to log in with both iCloud accounts and don't see the device linked to their accounts. However I do see the locked iPad on a list of trusted devices on another iPad they have.
Will removing this device from trusted devices remove that activation lock? What are my options here?
