How To: Motorola Atrix 4G Root - BriefMobile

found this method over on the xda forums, and it worked perfect for me.

i had a clean atrix running 2.2. i checked for update and did the OTA update to 2.3.4.

did everything in that guide, and i have root access now.

when you enter the fastboot boot mode on your device, did you have the usb cable plug in first ?, then enter command promt on your desktop

be sure to put your phone in USB Debug first.

i plugged in the USB cable after i enabled fastboot.

Was any data lost during the process?

I used the same method mentioned in the link above, but the /preinstall/dosu command would not work. So skipped that step and it still rooted my phone

Strange that it worked without it. For those the can't get the /preinstall/dosu command to work, what is recommended on XDA (and worked for me) is to use /preinstall/su instead. Not sure why it varies from phone to phone.

thanks for posting this. It worked great for me and I also now have wireless tethering.

I just tried this method earlier today. Everything worked up until I tried the /preinstall/su command. (I used su instead of dosu because dosu didn't work) It said that permission was denied. Any idea what went wrong? I tried going on to the next step as well, but it said permission denied again :/

phone info:
4.5.91.MB860.ATT.en.US
Android 2.3.4 (OTA update)

Hi
What happens after "fastboot reboot" command?
My phone restats like normal -
I used ----/su arnd it looked like it worked.
then the prompt seemed to be ==> root@localhost*

is that where the other commands are typed?
Thanks
Joe

A little late, but yes!

I finally got it to go through the whole process. After the last line, it said "success" but it did no thing to my phone... Did I not do something right?.... I just got a tablet and need th e tethering ability to get full use. If someone could point the way I'd be grateful

Thanks Milenko2121. The website instructions did perfectly root my Motorola Atrix (previously rooted but lost root after updated to Android Version 2.3.4)

The final command did result in the command line message "PATH=/system/bin:$PATH pm install /preinstall/Superuser.apk
pkg: /preinstall/Superuser.apk
Failure [INSTALL_FAILED_ALREADY_EXISTS]"

Nonetheless, my Atrix was rooted and obviously the message was because I had the SuperUser app left over from the previous Android 2.2 version.

Cheers and keep up the good work.
