The peeps over at xda developers never cease to amaze me, wake up in the morning and just scroll through the forums and you’ll always find something new. A method for free SIM Unlock for Samsung Galaxy S4 is now available. The method has been reported working on AT&T, T-Mobile and Canadian GSM versions of the Samsung Galaxy S4.
Warning
Neither we nor the xda developers are responsible if something happens to your device after trying this, please try this at your own risk. The method has been reported to work on TouchWiz ROMS or stock Samsung firmware only.
Here are the steps:
- Goto phone dailer, and enter *#27663368378# for the debug service menu (if this does not work try *#0011#)
- In “ServiceMode”, select [1] UMTS
- In “UMTS MAIN MENU”, select [1] DEBUG SCREEN
- In “DEBUG SCREEN”, select [6] PHONE CONTROL
- In “PHONE CONTROL”, select [6] NETWORK LOCK
- In “NETWORK LOCK”, select [3] PERSO SHA256 OFF
It should show:
SHA256_ENABLED_FLAG[1]
SHA256_OFF => SHA256_ON - Now touch the first line SHA256_ENABLED_FLAG[1]
It should show:
MENU NOT EXIST
PRESS BACK KEY
Current Command is 116631 - Now press the menu button and select “Back”
It should show:
SHA256_ENABLED_FLAG[0]
SHA256_OFF => Not Change - Again, press the menu button and select “Back”, and you’re back in the “NETWORK LOCK” screen
- Press the menu button and select “Back”, and you’re in the “PHONE CONTROL” screen
- Press the menu button and select “Back”, and you’re in the “DEBUG SCREEN” screen
- Finally, press the menu button and select “Back”, and you’re back in the “UMTS MAIN MENU” screen
- Select [6] COMMON
- In “COMMON” screen, select [6] NV REBUILD
Now you are in the “NV REBUILD” screen, you should see the following text:
——————————
Golden-Backup exist
You can Restore Cal/NV
—————————— - Now for the final step.
In “NV REBUILD” screen, select [4] Restore Back-up
The button lights for menu and back should come on, and the phone will auto reboot in a few seconds.
Let us know if you were able to sim unlock your Galaxy S4 using the above method.
