also do some research before doing it !!

and be sure, never flash sbf files or use rsd lite after unlocking the bootloader !!!

i unlocked my bootloader using the automatic unlocker (but i was on 2.3.4[4.5.91]) !!!

Wrong Version?

I am sure you guys are trying to help out, but most are missing an important fact in his request. I noticed this because I am looking for the same answer for the same version as the OP. 2.3.6

The solutions posted so far all refer to 2.3.4 and do not work with 2.3.6. The one updated thread with a link to a site that claims to work on 2.3.6, does not list the Atrix MB860 with 2.3.6, it does list it with 2.3.4.

This does not work, it gets an dialog box error "failed to chmod file: /data/local/tmp", then another that says "failed to get shell root"

The one thread that users claim it does work with 4.5.141.MB880.ATT.en.US, but that's not an option in the script. And they don't give a clue as to what steps they followed.

EDIT: Took a leap of faith, man that turned my stomach ( this is my wife's phone, I don't want to brick it ). I can confirm that the latest link past page 85 of http://xdaforums.com/showthread.php?t=1182871&highlight=automatic is valid as of 03/01/2012 and it is what I used. Followed the OP instructions and then then followed the prompts in the script. It did unlock, then I rooted and flashed CWM, option two.

This is a great thread for new users. I suggest you read it thoroughly. If you have questions ask after you have read up on the process that you are asking about.

Sent from my MB860 using XDA App

It has been a while since I rooted/unlocked the bootloader of my phone, but if I remember correctly, I followed similar steps as these.

Currently, I am using CWMs Touch Recovery, can be downloaded from their site, then flashed to the recovery partition using fastboot, I'm sure you know how to do this if you rooted the phone via command prompt. Do a google search, otherwise and current recovery image will do find for what you need, but read the reviews before flashing, some fail hard.

Once that is all done, you pretty much are all set, CWM Touch allows for backups to be completed, flashes to occure and wipes to happen.

I would also suggest that instead of just sticking with just jokersax, I would also suggest to check out turls, also available from jokers site. I personaly find turls to be a little more stable, and I seem to have minimal issues with turls, but everytime I see an update is available, I still jump to that one just to see what is up, then I may or may not jump back down, only because I can

After using turls and jokers ICS images, I haven't seen any downsides compared to stock, CM7, or any variants of the like, I love me my ICS. As far as official updates go, I wouldn't be too concerned about that, unless if somewhere else documented, I don't think the ATRIX will be seeing any official updates, but if something does show up, there is a script available on this site to resotre back to stock, then updates should work just fine. This tool seems to do the trick, I've used it personaly myself, got me right back to the stock moto install.

this is how

PROS:
* You will ended with an unlock bootloader (BL)

Procedure:
1. Download the attached file
2. Unzip the file inside of a new folder on your hard disk
3. Now is time to run the magic, go to the folder you just unzip the files in and double click or run "MAIN" file
4. A new windows DOS box will show up and just follow the procedure!
5. Flashing pudding part will take a little longer so be patience and let the magic do their work
6. At the end of the process your phone will reboot automatic.
7. Enjoy it!

Thanks to the2dCour for pudding sbf
Thanks to Tenfar for CWM (I prefer it due to the ABD option in recovery! NICE)
Thanks t0dbld for Mobile Hotspot patch

(*) Some users with 4.5.91 will need to run "fix" file to recover from a softbrick after the first attempt
(*) It seemd the new 2.3.4/4.5.91 pudding do a wipe after flash it, so have a backup just in case (I tested 1.83 and at least this preserve the data)
