giving u all the codes would be useless
u only get 5 attempts at codes
and each network will have at least 2 codes to try if not 3
so by the time u got to the last network which the phone would probably end up being on it would not be ablt to be unlocked anyway
only by cable
SOOOOOOO
you really need to find out what network its was originaly on
