  • Next choose “Debug screen”.
  • Now, choose “Phone Control”.
  • Choose “Network Lock”.
  • Choose “Perso SHA256 OFF” and wait about 30 seconds.
  • Press the Menu button then choose “Back”.
  • Choose “NW Lock NV Data Initiallize” and wait about 1 minute. Then reboot your Note 2.

  1. Thanks for the Post.
    Your 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.
