With the release of update 4.5.141 for the Motorola Atrix 4G also came bug fixes. Unfortunately, updating the Motorola Atrix 4G to the said firmware also meant losing root access. Thankfully, however, getting back root access is no problem. This method is similar to the one used to root version 4.5.91 firmware. If you aren’t familiar with it yet, have no fear. We’ll walk you through the process. Requirements You’ll need a few things: Motorola Atrix 4G running Android 2.3.6 firmware 4.5.141 A Windows PC (32-bit) Motorola USB drivers for Windows. Download the drivers from here and install them on your PC. A fully charged battery so that your Motorola Atrix 4G will not shut off in the middle of the update process. Make a backup of your important personal data. Make sure you’ve enabled USB Debugging through the path “Settings > Applications > Development” and check USB Debugging. Rooting files for the Motorola Atrix 4G (atrix-4g-moto-fastboot-win32.zip, 8.6 MB).

Instructions Once you have everything, you may now proceed to rooting your Motorola Atrix 4G:
Download the rooting files package to your computer. (See link above.)

Extract the ZIP file’s contents to c:atrix-4g-root on your computer. (You will need to create a folder named “atrix-4g-root” in c: of your computer. Turn off your phone completely.

Reboot the phone to Fastboot mode. You can do this by holding down the Volume Down button while pressing the Power button until you see Fastboot on the screen. Press the Volume Up key and you should see “Starting Fastboot protocol support”.
