How to Root Motorola Atrix 4G on 4.5.141 Gingerbread 2.3.6 Firmware

Procedure to Root Motorola Atrix 4G on 4.5.141 Firmware:

  • Now, you need to turn Off your device to enter the device in the fastboot mode which you can do by pressing the Volume Down button and Powering ON the device.
  • After this, you need to connect your phone to the computer with the help of original USB Cable.
  • In your computer, open the Command Prompt and enter the below mentioned commands one after another after giving the gap of a minute or till the command gets processed,

C:/moto-fastboot-win32

moto-fastboot.exe flash preinstall preinstall.img

  • Now, press the “Volume Up” key to start the fastboot protocol after which you need to type in the command as “moto-fastboot.exe reboot” and hit on Enter.
  • After this, your phone will be rebooted. Wait for the phone to get rebooted and then you need to type in the command as “adb shell” and press enter and wait till the shell gets restarted.
  • Now, type in “/preinstall/dosu” and press enter to process the command. If the command refuses to process, enter the below mentioned commands one after another,

“/bin/mount -o remount,rw /system”
“cp /preinstall/su /system/bin/”
“chmod 6755 /system/bin/su”
“PATH=/system/bin:$PATH pm install /preinstall/Superuser.apk”

  • After all the commands which are mentioned above, it’s now time that the phone should be rebooted by selecting the appropriate option in your device by using the Volume and Power button.

Tip: Just in case if the device is not rooted successfully or say if the process gets stuck at any point of time then you need to re follow the whole procedure from the start so as to root the device.

So, congratulations you have now successfully rooted your device by following the simple instructions mentioned above. Do share with us in the comments section just in case if there are any issues as we will try our level best to sort out the same.

    hi, is it a must to have at&t 2.3.4 gingerbread, or any original gingerbread 2.3.4 will suit this upgrade?

    Thanks very much for this guide!

    For anyone having trouble, I have a few comments about the above. However, first please realize that while I have a couple of decades of IT experience, I’m extremely ignorant of Android, Linux, and much else, so take this with that caveat.

    First, I didn’t catch that moto-fastboot-win32 was intended to be deposited in C: — that’s essential unless you point your command prompt elsewhere in later steps.

    Second, I believe the part above that reads

    C:/moto-fastboot-win32

    Should instead read

    c:
    cd moto-fastboot-win32

    Third, /preinstall/dosu didn’t work for me, but /preinstall/su did.

    Fourth, I got the “file already exists” error, but I forged ahead and by the end was rooted anyway. I suspect that part got accomplished in one of my previous four or five rooting attempts using a different tool.

    I was able to determine the device was successfully rooted by using an Android terminal app, typing in “su,” and seeing that I got a # prompt along with a friendly message about someone having requested superuser access and was that OK with me?

    I hope these notes are useful to others if anyone’s running into trouble.

    when i reach step 6 after adb shell, it says “error device not found”
    can you help from here please ?

    after reboot to write the adb shell command says the device was not found.

    • Reply Daniel Haynes June 30, 2012 at 2:50 am

      Ray

      You have to wait for a full reboot of the device after you enter the
      command “moto-fastboot.exe reboot”. When you arrive at your home screen
      on Android with all of the apps, then start the abd shell command stuff.
      It took me a while to figure this out. To check to see if the device is
      connected, type “adb devices”. It will list your phone if it is
      connected. Luc was also right about the “/preinstall/su” command as
      well. The one in the instructions would not work.

    Rooted on second try.
    After Factory reset lost SU. Attempted to root again and fails due to “file already exists”.
    SU app and terminal emulator indicate non root status.

      Gustavo:

      You need to first install the Atrix (ADB) drivers from Motorola. That is a pre-requisite before the pre-requisites stated in the article.

      • Reply Daniel Haynes June 30, 2012 at 2:54 am

        Yes and you need to make sure you have all of the tools installed with SDK for ADB to work right.

      HELP!!!???? After following the instructions to a “t”, when I type the “chmod 6755 /system/bin/su” command I received and error “No such file or directory”…..what is up with that. I rebooted and still no access to the root system. I have tried all of the different packages to root the phone with no success. Is there another workaround or am I just stuck and cannot root the phone in order to use the hotspot feature??? Please help. I am new android converted over from Iphone where jailbreaking and unlocking was a snap. My 4g is unlocked already. Could that be the problem?

    • Reply David July 3, 2012 at 10:55 am

      Thanks, your instructions were helpful and rooted no problems. Tip: To enter fastboot in Atrix you need to hold down power button and volume down button then once motorola logo appears at startup press volume down button again and fastboot will initialize.
