There is no direct root method for kitkat. You will need to downgrade to MK2 and install a prerooted ROM.
Follow the Deadly Venom Kitkat Magic Tool thread for further instructions.
Although the instructions in the thread is for NB1, it is still applicable to NC1 too.
EDIT: You need to flash the NC1 kernel modules along with the rom. The modules zip can be downloaded from post #1520 of http://forum.xda-developers.com/showthread.php?p=52231544

You have to downgrade to MK2, root and then install safestrap v3.72. The steps to downgrade is given in the tool thread.
You flash the custom rom from safestrap recovery. The tool thread would have mentioned flashing the NB1 kernel modules along with the rom. You would instead flash the NC1 kernel modules. The rest of the steps would be as per the tool thread.

I thought Bell had i337m. If you are on i337, the downgrade, root, and Safestrap doesn't trip Knox since Safestrap doesn't go in the recovery partition. That includes if you flash stock ROM with root or any custom ROM compatible, since Safestrap doesn't flash kernels.

This will put you on MK2 with root from NB1/NC1, then you can just flash the stock ROM in this thread (it has nothing changed but added root and an optional tethering addon) http://forum.xda-developers.com/showthread.php?t=2730144

ok a few more questions.
on link http://forum.xda-developers.com/showthread.php?t=2692825
the steps are:
1. Place the I337UCUFNB1_100%_Stock_Rooted_ROM in the root of your ext sdcard.
*2. Download the I337_NB1toMK2_Downgrade file(MD5:FAC95B4CC7743FAE34BC42EBFBAF751A), extract the .tar and flash in PDA slot in Odin(AP in Odin v3.09+) to obtain semi-functioning(no-wifi) MK2.
3. Use your favorite root method to root MK2, e.g. Saferoot, Kingo Root App, then install the latest Safestrap v3.72(NB1)apk (Download and learn more about Safestrap from this thread: http://forum.xda-developers.com/show....php?t=2448925).
4. Boot into Safestrap recovery, perform an advanced wipe, and wipe everything except ext sdcard.
5. Flash the ROM zip in the "Stock Slot."
6. Press "Home," then reboot into Download Mode and flash the I337_NB1_Stock_Kernel(MD5:A9B3BCD7CA16CB77652516E6117A5B81) in PDA slot in Odin(AP in Odin v3.09+).
so first question is how does one place something in the root of your ext sd card
secondly i honestly forgot how to use odin, dont i need to put my phone in download mode to flash? what is the sequence to put the phone in download mode if so? Does USB debugging need to be on?
also there is a note on this thread - once you have completed steps 1 - 4 below consider flashing the NC1_100%_Stock_Rooted_ROM from Post#3 in the following thread instead of NB1 to obtain the latest firmware: http://forum.xda-developers.com/show....php?t=2730144.
i know you might or might not have written any of these threads but you do have a clearer understanding than i do, that being said in regards to the note above would you say follow all the steps but use the NC1 ROM instead of the NB1 ROM? or Use the NB1 Rom do all of it then jump to the link you provided?

If you have an i337m you don't need or want safestrap. Just put a recovery on and start flashing roms. Here's a little help http://forum.xda-developers.com/showthread.php?p=41010145

Help with Rooting

Helping out a friend with an S4 with on NB1. Phone has been sitting for a while. He wants me to set it up with a custom rom or at least root it. Have dabbled with the Verizon S4 but never with the AT&T version.
Can the bootloader be unlocked on NB1?
If not, an you go back to an older release to unlock the bootloader?
Is there a prefered root method for NB1?
Is there any benefit in staying with Nb1 vs taking the OTA?
Thanks

The bootloader stlll cannot be unlocked on ATT S4. We still have a working recovery "safestrap". Safestrap doesnt replace existing stock recovery but is available during normal boot mode through a splash screen on bootup. Use safestrap version 3.72 or 3.75 and flash into stock slot itself. In case of issues, the phone can be recovered by Odin flashing the full NB1 firmware.
NB1 is not rootable. The next version NC1 is rootable with "towelroot". The latest NI1 is not directly rootable but can be rooted by Odin flashing the NC1 kernel.
You can manually update to NC1 and root.
There are a large number of ROMS that can be flashed on I337 including google play edition ones. AOSP/AOKP roms dont work though.

So the easiest would be to Odin to a stock NC1 and you towelroot.
Any links to the stock NC1?

We do not have odin file for both NC1 and NI1. There is an update file that can be used with "adb sideload" to update your phone. How to update to NC1 is there in the link I provided.

I tried towelroot to see if it works. It worked without a hitch. So I guesss the newest version works with NB1.

SGH-i337 OC3 Bootloader, what options to I have for custom recovery/root?

I have an SGH-i337 and had an MDL bootloader before moving to Cyanogenmod and then moved on to OC3 bootloader (stock Android 5.0.1). With OC3 bootloader, I did some google search but couldn't find a way to get a custom bootloader as well as root so I can flash into another ROM (the last time I did any unlocking, flashing, and rooting was ~ 2 years ago and methods/tools have changed so I'm not sure what my best options are right now). I read that TWRP doesn't work for newer bootloaders such as OC3 because loki is patched. Any advice/guidance will be much appreciated.
Thank you!

Safestrap is going to be your only option I believe

On MDL, the boot loader could be by-passed with loki, but everything since MDL, including OC3 has a locked bootloader and you are limited to stock kernel. Safestrap allows custom roms that are touchwiz based but no AOSP type roms. Also safestrap only works on 4.4.4 and below, not on 5.0.1. No root method has been discovered or posted for stock 5.0.1, but there is a keeproot upgrade method, so if you want to root, flash back to nb1, and then use the keeproot method.

So even if I flash back to nb1, I can only root it and not be able to flash to either Google Edition or Cyanogenmod (both if which are my ideal ROMs)? Could I not flash back to MDL, unlock the bootloader + root it, then flash to either of these two ROMs?

No now they have nc1 flash for 5.0.1 look at the i337 thread in xda

So I am essentially stuck with the stock AT&T Touchwiz ROM forever unless something like SafeStrap is available for OC3 bootloader? I'd do anything for being able to flash to Cyanogenmod or Google Play Edition--can't believe I flashed to an updated stock ROM by accident and now I lose all ability to flash to a custom ROM...

Yeah, it sucks and I feel your pain. But you are essentially correct. If you want to stay on Lollipop, then that's pretty much it.
You could flash back to nb1, root and install Safestrap, update to nj4, or install a custom TW based rom on 4.4.4.
You could flash back to nb1, root and use the keeproot method back to OC3, and then at least you'd have rooted Lollipop.

Thanks for the clarification--I'll check periodically to see if anything is available for OC3/NB1.

The only GPE ROM I've seen work on this phone is the dandvh 4.4.4 one and even then a few things were buggy. Though I enjoyed it.
iB4stid posted goldeneye v53 which is 5.0.1 for our phone which is pre-rooted and deodexed . It's still TouchWiz based, but with it being pre-rooted and deodexed you can use arter97's workaround and get Xposed working!
And lastly, you can use safestrap while on OC3, You just have to flash an Nj4 kernel in Odin, boot to safestrap, perform your actions, and then flash OC3 kernel back so lollipop will boot.
There are instructions for it on here somewhere. I would check in the "general" section. Sorry for not linking it, I'm on mobile.

Trying to use the keeproot method to get from NB1 (rooted) to OC3 (rooted). Problem is I can flash the ROM, but i need to Odin the OC3 bootloader after the ROM is flashed but I cannot find the OC3 bootloader for the life of me, I can only find the newer OK2 bootloader. Please help! Trying to at least get to Goldeneye on my I337!!
Don't tell me to just use the OK2 ROM and bootloader because when I used that to upgrade to Goldeneye I actually lost root access and had to go all the way back to NB1 and that's where I am now. Can I use OC3 Rom with OK2 bootloader??? God it seems like no one cares about I337s, the step-by-step guides are all over the place and quite hard to follow but I know where I'm getting tripped up. Please help!

Your baseband is OC3 so you have OC3 modem. What is your bootloader?
If you bootloader is newer than MDB or MDL you can not install the custom recovery like CWM or TWRP. You are limited to Safestrap or Flashfire for flashing the custom rom.

You have a locked bootloader so you option to install the custom rom is limited to using either safestrap or flashfire.
This guide explain how to install custom using safestrap.
This guide explain updating, rooting and using safestrap. It is also useful if you screwed up and bricked your phone while flashing or tweaking.
Flashfire is newer thing and there is no separate guide written for how to use it but you can find the flashfire instructions in the custom rom that is written as flashfire friendly.

My first reference explains all the steps starting from the Kitkat NB1.
Since you'd already have OC3 and rooted you need to follow the step #4 Install your CUSTOM Lollipop ROM . step 4.1 explains how to install safestrap. 4.2 explains how to invoke safestrap and 4.3 explains how to install the custom rom.
I did not see OC3 to NJ4 that you were referring to though.
This thread is for installing S6 port using either safestrap or flashfire. I am just showing you as an example how to install the custom rom.

I recommend you to do all process from NB1 to OC4/OK2 keep root (Avaliable on the INDEX) bcuz I was lazy and used kingroot to root OC4 and when I finally was into safestrap it doesn't flashed any ROM and was just a waste of time.

I'm not the most indicated to show you the way because I haven't tried the keep root method yet, S4 it's my personal phone, was finishing semester and needed to be contactable.
I'm gonna try it right now and if I have success I will let u know in a couple hours?
I'm now on Albe95 LolliROM v8 ? and I'm pretty noob on this. I'll tell you step by step tomorrow cause now I'm tired ??

So did everything is working perfectly, what steps u went through ?

Proceed at your own risk. I'm not responsible for any damage caused to your device
First we must put all the archives we will need on the SD card (Stock rooted OC4, the Custom ROM we want, OC4 modules, OC4 kernel and all we gonna need)
Make sure to read this complete, understand it and then proceed
1. I used Odin to flash back to NB1 (the rootable one)
2. Rooted with TowelRoot and installed SuperSU and FlashFire directly from PlayStore (worked for me).
3. Opened Flashfire, granted root permissions and did the Muniz_ri Keep Root Method (4.4.x to OK2) but instead of using OK2 replaced all OK2's with OC4 files because I couldn't find the OK2 modules and will be needed to flash custom ROM.
4. At this point we have OC4 rooted so we just install BusyBox (install the 'things'), then install Safestrap and inside the app install the recovery and at last install the NC1 app flasher.
5. We will automatically reboot into Safestrap recovery and there we just have to wipe (all except SD card) then we proceed to install the ROM (if the ROM has aroma installer at the end we don't reboot into system we have to go back to recovery), after modules and at last we flash (install) the Kernel (we re using OC4 base so modules and Kernel must be OC4 too).
6. From here we just have to wait, and the Safestrap robot will appear like 4 times, we just press continue and deodexed custom ROMs will take about 15-20 minutes to do the first boot.
