Greetings,

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?

Thank you!

I found this guide (http://xdaforums.com/showthread.php?t=2728462), but it just seems strange that the thread was all but ignored, so there is no feedback from users/testers.

You can upgrade to 4.4.2, but you don't keep root. You'll have to re-root it. And you have to use Odin which means you'll wipe the phone. If it was my wife's phone I wouldn't want to put up with the complaining of having to setup everything again.

You can first unroot then go to settings---->more----->about device----> software update and take the OTA to MK2. Once on MK2 take the OTA to NB1, then to NC1, then re-root using towelroot: http://xdaforums.com/showthread.php?t=2783157

The above process will leave your current set-up intact and rooted.

Would this method be the best way to unroot, starting with step 2 in my case since I still have root...or is there a different route I can take?

1. Re-root again using the same method you did before for MF3, then:
--a) Reboot, update SuperSU app and it's binary
--b) Reboot again, verify device status is back to"Official"
--c) Reboot again, verifying that, this time, the boot screen is back to normal again
2. Download a file manager app in the Play Store called "Total Commander" and enable "Root functions everywhere" in its settings.
3. Navigate to a folder called "/system/xbin"
4. Delete ONLY files in that folder with the word "busybox" within its filename or symlink path. You should end up with three files left. I did. Two of them are SuperSU related. DO NOT DELETE ANY OF THEM!
5.Open SuperSU and, in its settings, select the "Full un-root" option. Once SuperSU closes, reboot.

When you reboot, wait a full minute and check on device status. It should still say "Official" and you will be fully un-rooted.

Why does it stay "Official" with Busybox present ONLY when SuperSU's most recently updated apk and binary are present? I have no clue... But I hope this helps you out.
