I have an AT&T Motorola MB860, or by its regular name Motorola Atrix 4g running gingerbread 2.3.6, and i have tried rooting this thing so many times its making my head spin. The device just wont root no matter what i try. It is in USB Debugging mode and i unmount the SD card every time i attempt a root. I have tried super one click, Z4 Root, Rescue Root, ICS Root, and unlock root. In super one click it has an OS version check failure asking if my os is 2.0 or higher, and fails from there, and in ICS root the device shuts down completely once the process has started preventing it from rooting. I have updated all my motorola usb drivers as well and im still getting nowhere. In Z4 root which im using 1.3, i installed off of a website supplying the .apk file, it gets to shell rooting and the program fails completely. I have to reboot to retry and every time it fails. I put the phone in windows media sync to attempt the root each time and its just not working. The devices Boot loader is also still locked if that makes a difference in the devices rooting ability, but its infuriating me and I just cant get this to work! My plan is to root the device to make a full image file so that i can install full ubuntu dual installation alongside android. If the device soft bricks then i have the image file to recover android. please help if you can. I also have trend micro internet security installed on the phone if that makes a difference which i believe it shouldn't.
