Code troubleshooting: Samsung Galaxy S2, S3, Note, Note 2

Solution

The 2nd alternative method.
This method has been succesfully tested on multiple models but mostly on the Samsung Galaxy S2, Galaxy S3, Note and the Note 2.

If you are sure the IMEI is correct with the IMEI you provided us and the normal method to enter unlock codes does not work for you then try the following special method:

Follow these step carefully, as long as you have the correct code it will work 100%. Your phone must be updated to the latest firmware!

a. Go to the Dial pad and dial *#197328640# 

b. Please click on number [1] UMTS > [1] Debugging screen > [8] Phone Control > [6] NETWORK LOCK

c. You will see 3 options

d. Please click on number [1] Perso Sha256 INFO, the screen will change slightly

e. Please hit the MENU button then when the menu pops up please carefully hit BACK to return to the previous screen

f. Please click on number [2] Perso Sha256 ON, the screen will change again to a one line message

g. Restart the phone on the screen by holding the power button and click RESTART

h. When the phone prompts for the unlock code simply enter the unlock code

i. Your phone is now permanently unlocked!

If any of the special codes or some of the menu items as indicated are missing on your phone first make sure you have updated the firmware to the latest version and if you have done that and this method still does not work please continue with the next alternative method as mentioned here
