Soon after Motorola revised its software upgrade timeline, changing the original Atrix 4G's ICS ETA from Q3 2012 to a disheartening "further plans coming soon," a leaked Ice Cream Sandwich build has cropped up on XDA's forums. If you're the owner of an Atrix 4G and you're tired of waiting, there's good news - the leak, which carries an August build date, can be downloaded and installed on your device in just a few easy steps. Here's how it's done:

Disclaimer: Android Police isn't responsible for any harm to your device - proceed at your own risk.

Step 1.

Download the .zip here. If you haven't already, grab the appropriate Moto drivers here, and grab the MOTO-FASTBOOT application here.

Step 2.

Reboot your Atrix to CWM and wipe data and cache. Then reboot into fastboot, and connect it to your computer with a USB cable.

Step 3.

On your PC, open a command prompt (cmd) and navigate to the directory where both the leaked zip and MOTO-FASTBOOT app are located, and execute the following commands:

moto-fastboot.exe flash boot boot.img
moto-fastboot.exe flash preinstall preinstall.img
moto-fastboot.exe flash radio radio.img
moto-fastboot.exe flash system system.img
moto-fastboot.exe flash webtop vendor.img
moto-fastboot.exe reboot

Step 4.

Wait a few moments for your device to switch on (this part may take a while), and enjoy!

So that's it. Many users over at XDA are reporting success, though your mileage may vary. To keep up with the conversation, just hit the link below to see the original XDA thread.

Update: And it's gone. The thread over on XDA, as well as the .zip on dev-host are no longer available.

Thanks Dave and aa!

Thanks to Rhadamg and Epinter for instructions!

    I thought they made the decision not to update this device at all.

    • Random Idiot

      Looks like they actually tried to update to ICS 95% and decided to end the project. I think webtop had to do a lot about it too which this update doesnt include.

      • stewartsoda

        It does include the webtop, although I have heard mixed results in getting it to work (I haven't been successful with my lapdock yet).

    So, does this mean I can have video recording soon? I care not for ICS after having JB builds for a few months.

    • Jei Arc

      i hope the drivers for the camera are in there as well as the fingerprint reader so that people doing JB rom can use those, i love the JB ROM on the Atrix but camera is really finicky and of course fingerprint reader is non-existent :(, i truly do not want to flash back to ICS either

      • stewartsoda

        The drivers are there. I have used the FP scanner with this leak, but not video recording, although I hear that it works.

  • Chris

    Does the bootloader need to be unlocked

    • Jei Arc

      as far as i know yes Bootloader needs to be unlocked in order to flash any new rom since the last OTA

  • Cyklone

    Lol. ben running JB for a month now. Enjoy

    • ebswift

      It might be a good time to go read a few XDA threads...

      • Bluesoul

        Which rom are You running?, do the camcoder and GPS works on that one? Cheers!

  • Leandro

    Well, I updated successfully, but the phone is SUPER slow... while being awesome, yes, it works too slow... is because of the Atrix hardware??

      This is a debugging version. It has all sorts of reporting running in the background.

      Try to follow the thread here, and you will see a post about altering the mode to disable logging.

      no because Motorola didn't optimize correctly the droid 3 is the same specs as atrix it smoother then atrix on ics. I think Motorola didn't put much effort because they like to keep Verizon as number 1 priority

    I've already released a flashable zip, prerooted & busybox updated to 1.20.2 (contains- boot,system & vendor images)

  • nlabrad

    Can you change the link of the zip file to the epinters site? (Not the direct link to the zip file) So he can get some traffic through his site and some profit from it, in reward for all the work he has done for us the Atrix users, most of us don't donate, at least lets give him some traffic.
    It's a clean site, so looking for the link takes just a bit of scrolling.

    Thanks Epinter

    After reading over 40 pages of threads it might just be better to skip on over to the latest JB build, just as much risk anyway. And I need Webtop for my Lapdock so no can do there...

  • Floss

    Hopefully this build will help get CM9 up and running in a better state then it currently is :D

  • Ishkatar

    Installed this and my phone keeps rebooting... any ideas?

  • ishkatar

    Hi... is there a way of rooting this?

  • Chris

    File Not Found - XDA Has removed the link and any reference

    Atrix back to being stuck on GB (rumor is XDA was forced to take it down)

  • vijay

    After successful Installation, Phone reboots, Motorola logo comes up and black screen after 10-15sec, i hear a music and thats it nothing comes up black screen.

    • vijay

      Issue fixed, after multiple reboots, its ok now, i dont know how but now ICS is on my Atrix, Thanks for the Update, ICS looks gr8 and fast.

  • grellanl

    The epinter CM10 experimental build for the Atrix is pretty great - hopefully this helps build on that by allowing for hardware acceleration.

  • rrr
