Another question, after scouring this thread and others I haven't found an answer....
If I've already unlocked the bootloader and loaded a custom rom, CM12.1 in my case, how can this be done? In the not-stock ROM none of the dialer codes work. I don't completely know if something in the stock rom is adjusting firmware settings or simply something in the OS and if that's the case, then can it even be done on a non-carrier rom?
