Try this, I am not sure that it will work but it will take you to the screen for network unlock
.Goto phone dailer, and enter *#27663368378#
for the debug service menu.
- In "ServiceMode", select  UMTS
- In "UMTS MAIN MENU", select  DEBUG SCREEN
- In "DEBUG SCREEN", select  PHONE CONTROL
- In "PHONE CONTROL", select  NETWORK LOCK
Have a great day, enjoy!
Don't forget it takes less time to click the "THANKS" button than to type "thank you".
(unless you type very fast).
