Unlock code not working in Galaxy S3 Android 4.4.2

[Rjtoocool32]

Hi everyone,

I was able to unlock my Fido SGH-I747M running Android 4.4.2 KitKat with the unlock code provided by Fido.
However an error message was displayed upon entering the unlock code in the appearing prompt when a foreign SIM Card is inserted.

In order to successfully unlock the phone, this had to be done firstly:
1. Make sure that wifi and flight mode is turned off
2. Go to the Dial pad and dial *#197328640#
3. Click on number [1] UMTS > [1] Debug screen > [8] Phone Control > [6] NETWORK LOCK
4. You will see 3 options
5. Please click on number [1] Perso Sha256 INFO, the screen will change slightly
6. Please hit the MENU button then when the menu pops up please carefully hit BACK to return to the previous screen
7. Please click on number [2] Perso Sha256 ON, the screen will change again to a one line message
8. Restart the phone on the screen by holding the power button and click RESTART
9. Reattempt to enter the code
10. Now the phone is supposed to accept the unlock code.

These instructions have been published on the ebay by the member jmsobrino.
I hope this method will resolve your phone's issue as well

Wow. Great post. Thank YOU for this...
