I also have a question. I received this phone from my brother that was used by him having a gmail account that he did not use because he uses the email address from the services. He doesn't even know the gmail password anymore. I followed phone reset tutorials and saw that at some point it asks for a gmail account. I deleted everything from it, including the accounts. I would like to reset it for bring it as at the beginning and let me install what I need. If I enter the accounts, my gmail account, WHICH OF THEM WILL I BE ASKED TO RESET? I saw that there are methods to skip this step, but I don't want to complicate myself, make a mistake and block it.
