Sorry but it looks pretty bleak for root on the OTA, the S5 root thread is at $17,112.00 for root. Believe me there are some very talented devs working on this but with that kind of cash and no root it doesn't look good at all. It's for a different phone but it's the same 4.4.2 android os.
I have the paid SuperSU as well. The only thing I did different was not disabling it before updating. I did turn on survivability mode though. It wasn't obvious to me that I should have disabled SuperSU (since I wanted to keep root).
It isn't worth it. Even if they've rooted NC4 now, they lost all the benefits of the leaked bootloader (e.g., downgradability and "kexec" possibility). Additionally, they'll have no option to reroot or recover when needed––until finding a root method for KK, which could take a long time.
I think maybe you need to speak for yourself and not for everyone that has updated. As I've said before and will say as many times as needed, I don't need to be able to downgrade nor do I care about kexec. They are useless to me.
Sorry, but I didn't mention you in my reply. Anyone on NC4 may lose the root for some reason and then wait for a KK root method. The ability to downgrade gives an option to reroot when needed. However, you can do whatever you want.
That may be true, for you and for others. Reasons don't matter. But what I'm actually asking is (if you were on nc2) was there a quantifiable difference for you between nc2 and nc4?
Check if system/csc/feature.xml was modified by another app. Often apps that add features such as more apps to multiwindow and the pen window will edit that file. The update will fail if feature.xml fails a crc check. Hopefully there will be a backup if it was edited by an app.
This thread discusses some of the differences.
Let's say you have two files:
Have you done anything else to your phone? Maybe enable service menus? Something is not matching up with what should be stock.
