[Q] i337 4.4.4 Rooted. How to Unroot and return to factory topic

I saw a thread on how to unroot s4 on 4.4.4, but I can't find it anywhere. It's my wife's phone so I just want it to be returned to stock if possible so she can update to any new updates that come out soon. I used the odin towelroot method to root. I'm using safestrap as well. Any help would be great

[Q] i337 Flashing Modem from MK2 or MBL to NC1? topic

Hi,
My phone build number is i337ucufnc1 and my original baseband version is i337ucufnc1.
However, after following this tutorial "Possible method to SIM unlock on MK2 *must be rooted*" Method 2 , my phone was sim-unlocked successfully but now the baseband version is MDL (and I flashed MK2 later and it worked) I couldn't go back to NC1. I flashed it with I337_NC1_Stock_Kernel.tar.md5 but It didn't work.

Can you please guys guide me on how to restore it back to NC1?
Thanks!

[Q] Att i337 firmware odin fail topic

I have read read read cant find a specific solution ..Ok im on KOT49H I337ucufmld. I was on 4.3 before I have flashed with odin many times at first I got a fail at the start aboot.mbn nand fail ..so I removed that file and it started to install but failed at the end... my knox is set to 01 . my boot loader of course was locked down when I tried to flash another recovery.. so I read and people suggested pit files along with tar so I did that. no firmware Samsung official or otherwise will try to install at all with the aboot.mbn intact within the tar . ive flashed and flashed ..everything... so then I got a 32 gb pit file and did a nand erase in odin...and I noticed that by doing that I have my stock recovery back . I then re flashed the proper 16gb pit file and it remained working..so now I have download mode and stock recovery both working but have NO SYSTEM at all installed and cant seem to install one....I need good solid advise..is it a paper weight or is ther a way to zip or tar back either by odin or stock recovery.. help please.
