you can grab baf msl grabber to get the unlock code
as far as the question I have no idea of what you are asking
secondly how is there no esn on the device previously? it just sounds like we are getting into exceedingly illegal territory here is all...so I am asking for clarification of what the OP intentions are
as far as what you are requesting that does sound like esn tampering and shouldn't be discussed here...
