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.

Well I did read that ,actually if you look in my signature I already have a backflop running 2.3.4 on cm7. I am looking for what people think is best for the atrix. and the process for the new 2.3.6 update that caused some upset.

*EDIT* I'm sorry I did realize this wasn't posted from my computer

if ur on at&t !!
the best way to unlock is to use the automatic bootloader unlocker !!

for how to do it, here's a youtube video describing the same !!

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]) !!!

 

[good4y0u]

Well i need to unlock that to load custom roms right?

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.

Stock ics from moto is official for q3 its on there site ^.^. But i want is sooner. Im just worried the new 2.3.6 update might of changed something

You have to flash an SBF File to your phone Via RSDLite your phone will reboot a few times don't be scared
Then go to command prompt and type in command
fastboot oem unlock
Will give you Unique ID
Then type in
fastboot OEM unlock ############ unique ID
Then bam Unlocked bootloader
Make sure you use the correct SBF File for AT&T
And make sure you have A fastboot.exe file in your android sdk
To flash CWM flash it through the app first then flash it to your phone via Command Prompt
On command prompt type
fastboot flash recovery recovery press shift should auto correct make sure it is in the same folder as your Fastboot.exe

thank you so much! how hard is it to reverse this? ( the boot loader unlock) say if i need to RMA it to AT&T or something...also what do you guys use as a recovery and or what do you recommend?

 

[G-Man.]

Once you unlock your bootloader - you cannot reverse it - its permanent... you can never re-lock it.

 

[good4y0u]

so no more OTA updates?

 

[G-Man.]

Not easily - it can be done.... Most NEW Roms are built off the OTA's and are better than the stock releases..... OTA's are not really a big deal. Biggest issue with unlocking your bootloader is that it instantly voids any/all warranties.

 

[good4y0u]

*sigh* i know but mine is up as far as i know and i am already two years with the phone....so im just waiting for quad cores...

 

[alek_p]

i was able to return my unlocked Atrix to AT&T by flashing the stock 2.3.4 blah.blah.91 sbf. This does not re-lock it but gets rid of the Unlocked msg at boot screen

 

[good4y0u]

thank you ! that's what i needed to know!

 

[good4y0u]

so can i install a new recovery before i unlock the boot loader? which would you recommend? as i need to do a nandroid >.< , i did all this on my moto backflip...a while ago..and well....it didnt need an unlock..

 

[G-Man.]

*sigh* i know but mine is up as far as i know and i am already two years with the phone....so im just waiting for quad cores...

Atrix 4G has only been out for a year a and a few days..... lol.

 

[good4y0u]

They gave me an upgrade ......that's odd

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://forum.xda-developers.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.

 

[good4y0u]

Its the same as the 2.3.4 way. I figured it out an now have ics jokers rom
