Jump to: navigation, search

I created this guide as a walkthrough of my unlock process. It is intended to clarify the steps needed to do to unlock the Motorola Atrix.

First test

First thing to try:

./fastboot oem unlock
(bootloader) OEM unlock is not implemented
OKAY [  0.000s]
finished. total time: 0.000s

okay, I need to flash a unlocker SBF. (n.b. this wipes the phone completely!)
