My brother passed away last month and I would like to repurpose his Motorola android phone for our mom. To do a factory reset requires his google credentials, it seems. I have been able to successfully get access to everything I needed to handle his affairs except the phone and the google credentials. I don't care about anything on the phone. I just want the phone in it's virgin state. Is there a way to do this? I don't know what the model is since I can't get past the login screen.
