So I was wondering how to unroot my Droid 2 Global and have all rooted traces removed from the phone completely. I searched through threads up threads but didn't find anything good enough on the forum. I did some youtubing and below is what I founded. First I unrooted the phone using Z4 (thanks to the makers) then turned the phone off. I then flip the phone to display the keyboard. Held the X key on the keyboard and pushed and held the power button. I held both for about 10-15 seconds until there was an exclamation mark on the screen. 1. I pressed the search symbol key OR 2.With both hands on the still pressing power and the X key, I managed to push the camera and volume up buttons (have a friend help) and that took me to a screen that included wipe data/factory reset. Once I chose the option and let it do it's own thing, it rebooted. Phone was as new as it came out of the box. This worked for my D2G. I hope it works for any android phone.
