Activation Lock Error?
I bought an iPad Air last year from my friend. It was iOS 7.0.4 at the time I bought. And her iCloud account was unverified and always asking me to type password. But I could manage to remove her iCloud without typing her password all of a sudden and then I signed in with my account. I don't know why I could do that. The problem is Activation lock status is still on even I turned off find my iPad. The iPad is my iCloud account. So, if i turned off find my iPad, the website should say OFF. But always on.
1. Why? Is my iPad still links to previous account?
2. Will I be asked for activation if I ever do erase or restore?
3. If I was asked, Apple ID and password asked will be mine or her?
iPad Air, iOS 8.2
