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:

  • First up you need to Download Fast boot Files for Motorola Atrix 4G smartphone from here to your computer. Double click on “adb” and then on “moto-fastboot” icon so as to open the same in your computer as this will install all the essential tools in your computer.

extracted files Moto Atrix 4G

  • 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?

    • Pradeep Neela

      we will get back to you with the 2.3.4 version of firmware

  • Adam

    The link to hotfile has been taken down, any suggestions?

  • Luc Reid

    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.

    I opened the files after downloading, but I didn’t see any Moto-fastboot icon.! D:

  • Austin

    ok, i get to the adb shell part and it changes over to a $ sign, but the commands are all denied, even the extra ones, what do it do?

  • Luis

    Hey, is this tutorial working for 4.5.141? or 4.4.141? The article says one thing and the comments say another, please get this clear for us, thanks!

  • Rahul Meghlan

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

  • Ray

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

    • Daniel Haynes

      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.

  • Ron

    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.
    Suggestions ?

  • Bob

    I’m also getting permission denied when I try the commands in ADB shell.

    • Kosta

      I third this motion “/preinstall: permission denied”

      • Daniel Haynes

        Kosta.

        See my reply to Bob

        Daniel

    • Daniel Haynes

      Bob,

      Make sure to run CMD as administrator. If you right click on the launcher for cmd, you will see an option if you are using Windows.

  • Todd

    When entering
    moto-fastboot.exe flash preinstall preinstall.img

    I get an error saying it is not a valid Win32 application

    • Luis A,

  • Sam

    So, I’m trying to type in /preintsll/dosu, and then it says /preinstall/: permission denied. I have all my security disabled, and my firewall! Please help me! :D

    • Luis A,

      you first need to navigate to C:/moto-fastboot-win32 to do it type “cd..” en hit enter do it 2 times then type “cd moto-fastboot-win32″ now it should work

    • Daniel Haynes

      Sam,

      I had to make sure that I ran CMD application “as administrator”. Perhaps that will work.

  • Sam

    When I go to th flash preinstall step, and I type in “moto-fastboot.exe flash preinstall preinstall.img” it says “moto-fastboot.exe” is not recognized as an internal or external command, batch file. Please help, an I also tried dragging moto-fastboot.exe file in there itself and then after it typign “flash preinstall preinstall.img” and it says “Can’t load preinstall.img” Please answer both questions! Any help would be very appreciated! Thank you!

  • Deidrick

    Duh, why does this website say it works for 4.5.141? You are so misleading and need to start clarifying this better.

  • Gustavo

    after I type the command moto-fastboot.exe |flash preinstall preinstall.img” and press the volume up buttom the process get stuck, nothing happens, the phone says “Starting Fastboot protocol support” and the cmd says “waiting for device”, help please.

    • Michael

      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.

      • Daniel Haynes

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

  • Rafa

    Hello

    It doesn’t found /preinstall/dosu and the manual process /bin/mount… what can I do.

    • Jim

      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?

    • David

      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.
