Phone code does not work even if it ask for it. When flash LineageOS rom via TWRP (Marshmallow), phone asks for code, but code not accepted, because it's on custom ROM.
Only unlock from professional need, maybe xtc2clip box needed.
i wrote 4.27.502.7 ROM, it's not firmware.
my phone's firmware version is 3.38.502.41.
my question is the same: may be it's S-ON prevents flash firmware.zip added to youtube video?

i must flash ruu 3x - yes?

Hi, guys!
To all who runs AT&T M9 Firmware Locked to AT&T.
A lot of people can't run Nougat, bacause AT&T didn't want to share update signature key outside AT&T network. If you are not in US, you can't get Nougat update.
Does anyone have activated AT&T sim? Just flash your M9 by latest MM...
