Is your friend planning on ditching his contract without paying the termination fee? Your friend, if he wants to cancel his contract early will need to pay the remaining price of the phone or return the phone. This is on on their website. If he plans on ditching his contract and not making the remainder of the payments and does not return the phone, it could be blocked. If he is going to charge you know what he owes for the phone then he needs to give that money to T-Mobile. As long as the phone is paid one way or the other, the phone will be clean and you can bring your own phone to T-Mobile using the BYOD plans.
