However after doing all the instructions and getting the cell rooted when I type the code *#197328640# I only get the same menu that was there when I had the 4.1.2 version on the cell, and of course it will not let me unlock the phone.
Is there any other way, like modifying some file or something like that, which could help unlock it? I am not afraid of having to use and editor to mess around with files. Any help will be appreciated.
type the code, go to 1.debug screen, then 8.phone control, and then 7.network lock. i'm currently on 4.1.2 (with mg4 modem), and i can't get past 7.network lock (it says menu not exist). please let me know if on 4.1.1 you are able to get past 7.network lock and unlock the phone, cause i want to downgrade too on 4.1.1 for unlocking.
Don't forget to press the "Thanks" button if i helped you!
