You can't get CM 12. Farthest you can downgrade is to NB1 and then you still only have Safestrap with Touchwiz 4.4 ROMs and the few working GPE ROMs.

This only recovery you can use is safestrap, or you may be able to use Flashify, but either way you can only flash tw based roms.
Ah, I see I was too slow.
Ok thanks for the help.

I am new to flashing so sorry if I have asked some stupid questions.
I have SGH-I337 (ATT) and would like to root and then maybe install Cyanogenmod or any other custom ROM.
Device Details:
Baseband - NC1
Build No. - NC1
Android Version - 4.4.2
I tried to root NC1 directly using motochopper. Then I read and I am now trying to downgrade.
I have got ODIN 3.09 but it does not say support to I337. I have gone through Noob Helper
I have downloaded all zips from Downgrade
After reading the article of Modems; I got confused about my bootloader.
I also have gone through the thread but after that confusion, I did not proceed ahead.
Could anyone please help me?
How to identify boot-loader?
Which ODIN to use or do I need to use SAFETRAP (not sure if bootloader is MF3) ?

Dont worry about Odin saying the device is i9505 or so. The flash will work.
For samsung phones running full stock firmware, all the components have the same version. Since your build is NC1, your bootloader is also NC1.
You are in the right track. Follow the downgrade thread to partial downgrade to MK2. Then use saferoot to root. Then install safestrap v3.72. Then use the deadly venom kitkat magic tool to install any kitkat rom of your choice from this list (post 3).
You cannot install any AOSP based rom. So, no CM. Even google play edition roms dont work.
You can install AOSP themed roms (like BlackBox3.0)

Thank you for the response. I have downgraded to MK2 and have done the root.
I was wondering if you could tell me if it is possible to install Liquid Smooth ROM. I have seen the video and I have downloaded from here which says S4 unified. Also, there are some videos claiming CM on S4.
Could anyone please help on the same?

As already stated, no AOSP based roms will work (ROMs that are built by compiling AOSP code). Only TouchWiz based roms will work. If you need AOSP look and feel, you can install an AOSP themed rom.
CM/AOSP on ATT S4 is only possible if you have the MDB/MDL bootloader. Anything above that, it wont work.

Sorry for the repeated questions.
I tried to update through Safestrap with BlackBox. But I got stuck on the boot screen where it shows Samsung Logo. I might have done something wrong. I just clicked next on BlackBox 3.0. Could anyone please help me !
Edit:
When I tried to reboot into recovery mood (Vol Up + Home + Power) it says:
" Secure Fail Kernel
(Warning Sign) System Software not authorised by ATT has been found on your phone"
Don't select the reboot now option in the aroma installer at the end. Then, after the ROM flash is complete and before you reboot the phone, you need to put the phone back in download mode and flash the MLD ap/bl/cp files from the tool

I flashed the NB1 using ODIN but it still stays on Samsung Logo with custom logo. I am not able to navigate any where else from that screen.
Edit:
I was able to go into system recovery. Please let me know if I can fix the error somehow.
Thanks a lot !
Get into stock recovery and factory reset. I am not sure why you flashed NB1 though, as there is no direct root method for it yet

He probably was following the steps that were provided elsewhere here that had you go from nc1 to nb1 then back to the M (I can't remember which M) one.

I had rooted MK2 and the installed the custom ROM (Blackbox) and then was suppose to flash NB1.
So, if I just did a factory reset it would solve my error?
Thanks for the help!
Edit:
I tried doing the factory reset. It just wipes all the user data. And I am still stuck on the same screen with Samsung and the custom logo.

Do you have an i337, because if you do the bootloader is not unlocked. You're going to have to flash the stock firmware in Odin

You're screwing up because you haven't read about the things you are trying to do. If you want to learn and do things correctly, I suggest reading the pinned threads in the general and q&a sections paying close attention to the information that is specifically about your model and firmware version. The things you are trying to do and the questions you are asking have been answered many times over in those threads.

You need to flash full nb1 to regain stock.
Once you are in nb1 you can choose to stay stock or downgrade to mk2 to root and install safestrap.
From there you can install any Tw rom not AOSP YOU CAN NOT FLASH CUSTOM ROMS.

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.

So I'm on 5.0.1 I want to root my device, install a custom recovery so that I can sim unlock the device. Everywhere I read, it's only possible from 4.4.4 and lower. So my question is, how do I downgrade? I know how to get into recovery. I know how to sideload files. I'm all ears right now. Someone show me the way.
Update: I followed this tutorial and everything worked out fine. I am now rooted on 4.4.4
If you have an Galaxy S4 AT&T you have a locked bootloader, that means you cannot install a custom recovery.
You can go from 5.0.1 OC3 to 4.4.3 NB1 using Odin.

so if the BL has always been blocked how have i been able to install custom recoveries? ie TWRP and SafeStrap... am i wrong in thinking they were custom recoveries?
Ahhh you have a i337 with LOKI exploit. Im.not sure but if you install a stock system(vía Odin) you will lock your bootloader for ever. Search in the forum.

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!
