Motorola Atrix users should be expecting an OTA update this evening (or at least sometime soon), according to Motorola's Global Portal (corroborated by reports from Atrixforums.com). The update evidently includes a handful of improvements, from the "latest Google Android security fixes," to stability improvements, as well as Bluetooth, Wi-Fi, Messaging, and Contacts enhancements. Here's the full list of highlights from Motorola's site:


For those who are curious, this update will break root access. If your device hasn't received the OTA just yet, you can hit Settings > About Phone > System Updates, then download, install, and enjoy!

    4.5.141?! Are we talking ICS here?

    • http://www.AndroidPolice.com Artem Russakovskii

      Nah, that's their internal software version.

      LOL i thought same ! But it is build number !! :P

  • Dandmcd

    No thanks Motorola, I like ICS and not rolling back to your Blurified crapola.

    Thanks for the tip! Downloading now.

    This update will break root, but root can be regained through the fastboot method. The fastboot method can be found here http://briefmobile.com/motorola-atrix-4g-root. Just a side note, you will need to make sure all traces of root is removed from your phone or the method will fail. Also, those that are hoping for ICS will get it 3Q of this year. Check it out on the Motorola Software Update page.

    This will brick if you used pudding to unlock the BL and don't still have stock BL. Wait for a fruitcake, hopefully someone will someday make one.

    My build number is 4.5.2A. Am i daft for thinking that 4.5.141 as a smaller number is therefore a step back.

    • Mgamerz

      Its for US atrixes only.

      • Nick

        Thanks..... but how did you know mine wasn't a US Atrix? Just curious.

        • Mgamerz

          I have a US atrix and the only updates I have had are 4.1.57, .83, 4.5.91, and now .141. On XDA's fruitcakes thread (bootloader unlock safe upgrading), there is one called 4.5... something A. I think it was France. I know it was not under the US one. Not sure.

    Please be a little more professional when making these posts. It would be useful to specify: OTA update for AT&T Atrix users. The world is slightly larger than AT&T.

  • Hiram Lester

    OTA Rootkeeper, which Android Police mentioned in another post, will let you keep root if you load it and backup the su binary BEFORE the update.

    • Dark

      OTA Rootkeeper will only work if you used a root method that uses the zergrush exploit. Most of the one click methods do. I used one that edited build.prop and OTA Rootkeeper failed me. Ended up flashing a sbf of the update so I could root using the fastboot method.

  • Andrew L.

    Wi-fi on my Atrix constantly drops after the OTA update. I've updated my router firmware, no dice. =(

    • Shawn W.

      I have been having the same issue. I have tried everything I could find, even factory reset, with no results.

  • O.Dillard

    I am new to Androids. I have had my Atrix 4G for about a month now. What doe "will break root" mean and what is a Rootkeeper?

    Thanks for helping a newbie...

      O. Dillard,

      Here is a helpful link:


      "Breaking root" means losing root access. The latest OTA update for the Atrix makes your phone lose root access if you've previously rooted. If you're running "stock" OS (you haven't rooted your phone), this doesn't effect you.
