How To: Motorola Atrix 4G Root

Root method found and executed by Brandon15811, the2dcour, and of course eval-! Make sure to thank them over at the forums.

Prerequisites

Outline

Extract the ADB-Fastboot package and root image to your C:\ Drive under a new folder titled “root”
Put your device into Fastboot mode: – Turn off your device. – Hold down the power button and downward volume button until you see “Fastboot” on your screen – Push the upward volume button
Open your command prompt (Start >> run “cmd” >> enter)
Type the following commands
- cd C:/root
- fastboot flash preinstall root.img
- fastboot reboot
Enable USB debugging (Settings >> Applications >> Debugging)
Type the following commands
- adb shell
- /preinstall/dosu
Type the following commands
- /bin/mount /system -o remount,rw
- cp /preinstall/su /system/bin/su
- chmod 6755 /system/bin/su
- PATH=/system/bin:$PATH pm install /preinstall/Superuser.apk
Congratulations! You are rooted!

PATH=/system/bin:$PATH pm install /preinstall/Superuser.apk

After entering the adb shell command, I only get a $ at the prompt and when I try /preinstall/dosu at that prompt I get nothing and no further action. Any ideas on what I’m doing wrong?

um, you are missing the step to conect the phone to the pc, and also what setting for the atrix usb connection?

Worked brilliant, thank you. (Atrix 2.3.4 – Telstra)
For ”
/preinstall/dosu”, I had to replace “dosu” with just “su”
So the command reads as follows:
“/preinstall/su”

i need help. i got the fast boot and my phone says starting fast boot protocol support but when i try to type the commands it wont work, is there something i need to do before rooting my phone or anything im not doing?

I have found if you were previously rooted and updated without completely removing all traces of root from your phone; this method will fail. You can try flashing an sbf (what i did) and then uninstalling superuser like you would uninstall any other app. Another method if you don’t feel comfortable with sbf’s, you can try downloading the Motorola Software Update Tool which should allow you to reinstall the current software version you are on (did this when I accidentally screwed up the cardock app and couldn’t fix it). Anyway you decided to do it should romoved all traces of root. Once that is done you should be able to use the fastboot method.

Couldn’t you put a newer superuser
