Default Gt-n7100 4.1.1

Hi everyone!!

I have a Note 2 GT-N7100 from Telcel mexico.

I tried to unlock , but the rom stock 4.1.1 from the operator doesn't have the complete menu, UMTS does not appear and is incomplete.

Exists an original SAMSUNG ROM 4.1.1 that i can use to flash and the menu appears full to make the unlock ??

greetings from mexico!!
