Here we go again, folks. Another Ice Cream Sandwich ROM arrives for the Motorola Atrix 4G, and this time it’s none other than a kanged build of Cyanogenmod 9 or CM9. Cyanogenmod, or its kanged builds, as you all know, is a free, community built, aftermarket firmware distribution of Android 4.0 (ICS), which is designed to increase performance and reliability over stock Android for your device. This is an early build, and one can expect some bugs, mainly arising out of the CM9 base, which itself is under heavy development at the moment. But anything CM9 is definitely worth a try, right?

How To Install CM9 on Motorola Atrix 4G

  1. Download the CM9 ROM & Gapps Package zip files to your PC, from the original development thread.

Now, hit Volume Down repeatedly until you see the option in top left changing to Android Recovery. Once you see Android Recovery, hit Volume Up button to select it and your phone will boot into recovery mode.)
  4. [Optional] Perform a full Nandroid Backup of your existing ROM, so that you can always restore it from recovery if something does not work out with this Rom. To perform a backup, select Backup and Restore » then on the next screen, select Backup again.
  5. Next Select “Wipe data / factory reset” → confirm Wipe data/Factory reset on the next screen (will not erase your SD card, so don’t worry)

  9. Now, select “Go back” to return to the main recovery menu. Scroll to “Install zip from sdcard” and select it. Select  “Choose zip from sdcard”. Scroll to the CM9 zip file you transferred to the sdcard in Step 2 and select it. Now confirm installation by selecting Yes – Install update-cm-9.0.0-RC0-Atrix-KANG-signed-6.zip. The CM9 ROM will start installing.
  10. After the installation is complete, select “go back”, but don’t reboot yet. Select “Install zip from sdcard” again, then “choose zip from sdcard”. Browse to the Gapps package zip file now (transferred in step 2) and select it. Select “Yes — Install “gapps-ics-20120215-signed.zip” on next screen to confirm installation. This will install Google apps like Market, Gmail, etc.
  11. After the installation is complete, select “Go back” then select “Reboot system now” to reboot into your Atrix 4G, to be presented with Cyanogenmod 9, aka CM9.
