Okay I rooted my Bionic a couple weeks ago just to be able to wireless teather while on vacation. I would just leave it as-is but i get random shutdowns so I want to go back to stock. How do I do it? I know very little about rooting(was lucky to even do it). I was getting a upgrade notifacition and tried updating it but it failed 2 different times. Also I installed romtoolbox and played with my status icons some if that matters. I also did not make any backup at any time.
