I have a US Cellular version that worked with no tweaks using a GSM BYOP TracFone SIM. Activated immediately.
I'll try and unlock the bootloader tonight and let you know.
I got the Razr M almost a month ago now. I love it, but I miss root (I had Galaxy S international) terribly! I would work on exploiting it if I knew how to begin. I really think this 'it's not the dev edition so buy a new phone' mentality is just ...
I got the same error message.
Mahera sent me the fix on Telegram. Here it is:
Edit the PL2-222E-0-00WW-B02.mlf and modify these values as shown below and save:
INITOPTION = 0x20000
INITDLTYPE = 0x60
SECURITY_VER = 0x0001...
I just unlocked the bootloader. It's a go!
(bootloader) Bootloader is unlocked! Rebooting phone
OKAY < 0.697s>
finished. total time: 0.699s
Please make a Moto Maxx forum so it is separated from the Droid Turbo. Thanks.
