I have been really frustrated with my phone lately. I’ve wanted to flash it with a non ATT ROM for while now however I haven’t had the time and the Atrix’s locked boot loader has made this project a non-starter for me. Not to mention that all the tools required to flash Android devices require windows boxes which is beyond me.
When the phone’s blue-tooth stopped working it was the last straw. I had some spare time today and commandeered my girlfriends windows laptop for a couple hours to give it a try. There is a lot of info out there on how to do do this, however the instructions were still not very clear to me. After reading a couple different xda forum posts and watching a couple of videos, I gave it a shot. Basically there are three things you need to do: 1)Unlock the boot-loader, 2) root the phone, 3) install a custom ROM. This post contains a steps I used to install CM7 on my ATT Motorola Atrix 4g. For more info check out this thread at XDA forums….
However if you are still confused like I was, here are the three steps that need to be done and the order I did them in……
1. Unlock boot loader..
I followed the instructions form Johnnythegeek here……
xda post on this:
*note I did hit the soft brick issue mentioned in the video, however following the instructions in the script resolved it. It did take a reboot or two to get fast-boot to come up.
** also note this will wipe your phone so make sure you back everything up.
2. ROOT the phone
I used the steps described here, there is also a video form johnnythegeek on this….
3. Flash ROM
Once the boot-loader is unlocked and the phone is rooted you can do the remainder from the phone via ROM-Manager downloadable form the google app store. You will have to dowload the ROM’s and copy them to the SD card. I used the CM7 beta ROM and the google apps add-on, below….
Johnny has another video that covers this, I did not use this one when I did mine, but it may help. He talks about ROM manager about 13 an half minutes in to the video below……
