ReplyDeleteYour method worked well in my Dad's Note II and even in my Sister's Galaxy S3 . But when I tried it in my Galaxy S3 LTE it didn't work . So,I contacted my service provider to get the unlock code but they said I have wait until my contract is over which is two years. So,I searched many site and found Unlock code for cheap price in ProUnlocking.com and unlocked my phone.
