Just bought the V20 because it was the only att phone with possibility of root. Had it 3days and it kept telling me to install update (had auto update turned off). Wanted to read into the posts about how to root. Overnight it installed on its own. Now I'm assuming I'm stuck. I still have a week (this week) left to return it. I'm thinking maybe return under the guise of wanting a different color one just to get one still running the December security patch. Any ideas?
