I am using z899vl model phone. I bought it off another person using it previously. The person I bought it from isn't answering the other number they provided. They failed to give me the original email tied into the Google account, thus I am having to circumvent all of this by master resetting the phone. I am unable to plug the phone into a computer. How can I clear the email and sync my email to the phone I bought? Do I need to root and replace one of the files, editing it to delete the email to the phone and manually type in my email? Any one else have the same problem with a used phone?
