What happens that the account is from a client and supposedly the user who gave me is correct but I did not see it very safe,
look, it is easy to know if the account is correct ... when you ask to enter it to unlock the cell phone, the next step that tells you is to put the password .. if it is not the account, it will tell you that account does not is associated with the phone, and therefore I would not be telling you the truth
then you can not do anything you .. the only ones that unlock them are the samsung service, carrying the equipment with a purchase invoice .. at least I do not know anyone who can unlock the equipment when it is in that state
