After my daughter got a smartphone her Samsung Tab A tablet has been sitting in a drawer for two years. I just bought a Wacom drawing tablet and she wants to use it with her tablet. But she doesn't remember the PIN of the Tab A tablet, so we tried to factory reset it, however she doesn't remember what Google account she used on that tablet (or the associated password). Recovery of the google/gmail account is impossible, we tried everything.

 

What can we do? I bought that tablet brand new so surely there's a way we can still use it right?
