Ok I rooted my att note 2 and all was fine and was running the stock rom. then i saw that there was an update for 4.2.1 which would give the ability for multiple windows, so i loaded the update knowing it would most likely unroot my phone. if i were to re root at this time i would still keep 4.2.1 and not go back to 4.1.1 right? fyi i used the chain fire odin method from xda and it worked flawlessly
