My wife's S4 is on 4.2.2 (MF3) and it drives me nuts. I've been looking around the forums, but haven't found anything conclusive as to if there is a way to go from 4.2.2 to 4.4.2 and keep or reroot.
Normally I'd throw caution to the wind, close my eyes, and hit start... but, being that this is the wife's phone and that she is perfectly content with 4.2.2, the last thing I want to do is screw up her phone.
So I guess the question is: Does anyone know of a guide they can point me to that upgrades a rooted 4.2.2 to 4.4.2?
I found this guide (http://forum.xda-developers.com/show....php?t=2728462), but it just seems strange that the thread was all but ignored, so there is no feedback from users/testers.
