[Q] Need help to access UTMS screen
I have a Samsung Galaxy S4 mini GT - 19195, I try different methods, and google this phone model with secret codes to access the UTMS screen, but none of them work.
I try *#0011#, it didn't work.
I try *#9090#, it only took me to USB debug, and DBG msg on or off options.
What other codes I should use to access the UTMS screen, then access to phone control, and network unlock? Any instructions you can give me?
