Is there anyway to uninstall this or roll back? And slightly unrelated, how do we unroot? Do we just run the 1 click root program if we used that, or do we need to do some adb work? Just want to see if I can roll back easily in case something goes sideways.
No way to roll back. Currently there are no "do-overs" on the Droid 3. No .sbf, no alternative recovery, etc...
Remove root with the unroot one-click method posted over at XDA or just (while root), remove busybox, superuser.apk and su. Reboot.
