V3xR_J how enter unlock code
 

Hi I receive code for unlock motorola V3xxR_J R272311 locked to AT&T but when I turn on the phone with a non AT&T simcard for ask me for subsidy code the phone just freeze in AT&T logo but if I insert a AT&T card the phone turn on normally not freeze, Ive tried with many simcard but its the same. I flashed the phone with 2 different sw ver for this phone but still the same.
So if anyone knows how I can solve the problem will be great!
Thank you in advanced.

Some advice mates????

Give it a try.

When the phone starts to freeze at the SIM acknowledgment type C 073887*
If asked for security code put 000000
This opens up the secret menu to enter NCK .

Ive tried your way without results, thank you very much for your support buddy :(
