help with rooted htc hd2
I just got this phone off eBay. it was already rooted and the problem I'm having is the previous users gmail account is connected to the play store so I'm not able to download anything from Google play because I don't know the password to that account. which also keeps me from being able to delete the account as well. basically everything is synchronized with this persons account and I can't do anything about it. I keep getting notifications on "sign in error" for this account. so my question is, is there anyway yo remove this account or unroot my phone? I'd like to keep it rooted because from what I've read, this phone is better with android over windows. but not being able to personalize my phone because of this persons gmail account is very frustrating! hope someone can help.
