well im thinking fo doing it right now... but one question though.. when i'll get the update notification from ATT will it recognize that my phone is already updated? or it wll continue to nag me all the time without possibility to get rid of it?
I don't think it will nag you since it is already updated but I'm not 100% sure. The Atrix is my first Android device so this is only my second update. I was an iOS device user before so updates are much different. I recall from the first OTA (update to 4.1.5.7) that the phone kept nagging until I downloaded it.
At first when I did this manual update and the phone rebooted, I thought it didn't do anything because all my apps and homescreens were all intact. I tried to use Titanium backup and it said that I didn't have root access anymore but I was still able to download apps from Amazon App Store. So, I went back onto xda and found an app called "Gingerbreak" and sideloaded the apk onto the phone. This particular app roots the phone and installs Superuser. Once the phone rebooted, I was back in action.
