I have an ATRIX 4G 2.3.4 AT&T 4.5.91. It was rooted at one time but somehow lost its root. I also disabled my BlurUpdater.apk when the phone was rooted to avoid update messages. I am unable to enable the BlurUpdater because I am no longer rooted. So I am trying to reroot my ATRIX to enable my BlurUpdater and are running into problems:
C:\Root>fastboot flash preinstall root.img
sending 'preinstall' (32768 KB)... OKAY [ 4.118s]
writing 'preinstall'... OKAY [ 2.278s]

C:\Root>fastboot reboot

C:\Root>adb shell

/preinstall/dosu
/preinstall/dosu: not found
$ /bin/mount /system -o remount,rw
/bin/mount /system -o remount,rw
/bin/mount: permission denied
$
The /preinstall directory appears to be an empty directory.
Any help is appreciated.
