Unroot the S4

[aka848]

I just heard about the impending release of 5.0.1 for the verizon s4.
I rooted my friends s4 a few months ago, and unfortunately, he just has not found it to help him much. I am relatively sure he would rather have lollipop.
So my question is this
How do I unroot his phone (on the latest NK1 firmware) without losing any data. He really wants to keep all his stuff exactly the way it is.
Thank you!

SuperSu has a unroot function, but it MIGHT brick the phone. Best thing to do is get the NO WIPE TARS for NK1 and use Odin..

Could you give me link on a tutorial for that or something? (no wipe tars didn't give me anything relevant on google)

Thanks!

It's not just unrooting. He will need to have all the stock apps, and if he changed any stock files, they will need change back. Nest bet is to use Odin and reflash the stock ROM.

He hasn't done any of that. The most he has done is installed Xposed, and he didn't find it compelling. Can the rom be reflashed without erasing the data? He is going to be real mad at me is I have to reset his phone to get him 5.0.
