I'm unlocking a verizon galaxy s3 sch-i535v for a friend to use on at&t. i know how to root the phone but its been a while since ive carrier unlocked a phone i remember having to go threw the files and changing and deleting some things but i don't remember what i had to change or delete. can someone point me in the right direction to a site or something? i also should mention that the secret code does not work because he updated to the latest os.
~thanks in advance
