There are plenty of threads with information in the general section, including a thread convienently named All Things MK2 And NB1. Make sure to check that and read more before asking questions unless you're on an I337m, in which case you can disregard anything I've said ;P

you can't unlock it. If you have MDL firmware you can use an exploit but if you are on MK2 of MF3 its completely locked down

[Q] Cyanogenmod installer confirmed working with AT&T GS4 SGH-I337?

The question is will my device work with the jflteusc version of the CyanogenMod Installer? I have a AT&T Samsung Galaxy S4 SGH-I337. I heard of the new CyanogenMod installer and looked at the supported devices. I saw a jflteusc (US Cellular). I don't knoiw if it will work with my AT&T S4. I don't want to **** up my phone. I'm currently on 4.4.2 NB1 stock rooted. The website I am referencing is http://wiki.cyanogenmod.org/w/CyanogenMod_Installer Any help would be great!

Did you use safestrap and deadly venom kitmat magic tool in install 4.4.2 stock rooted? If so, you cannot get CM to work.
Yes I did. If I upgrade to NC1 stock unrooted, would that work?

You have a locked boot loader that prevents from changing the kernel. So, no.

There has to be a reason why only ATT S4 is missing from the list, right?
Yea I downloaded the app and it said device unsupported
Sent from my SAMSUNG-SGH-I337 using XDA Premium 4 mobile app
Has anyone ventured to trying the installer in the unsupported mode? Is there a reasoning behind this and safe to try if I'm already rooted and TWRP? I thought there already was an ATT compatible build.

If your bootloader/firmware were MDB or MDL you could try it. Above that there is no exploit for the bootloader out yet so you can not install the CM.
Yes I'm on the same adventure with my sgh-i337. I'm going back and forth between MK2 and NB1 ROMs but cannot get MDL or MDB flashed at all. I got them from samfirmware and Odin fails. I tried kies and it says firmware available is MDL ... Well great, but then it says device not recognized!
I'm really torn between why is it we can get to MDL to flash CM?
Instructions:
http://wiki.cyanogenmod.org/w/Install_CM_for_jflteatt
Edit: once updated to MK2 there is no going back. Bootloders are locked and that is the end of the story. No more CM or CWM recovery or Loki ... Just safestrap and custom ROMs.
Sent from my SAMSUNG-SM-G900A using XDA Free mobile app
Just as a final reference for all: CM installer is not for the I337.
On MF3 and above, we have no exploit for ROMs and Cyanogenmod is not compatible with our stock kernel.
Even on MDB/MDL it won't work because you need Loki which the installer doesn't take care of AFAIK (if it were to even let you open it).

There is no direct root method for 4.4. So, you have to follow Deadly Venom Kitkat Magic Tool.
Using the tool, you would first partial downgrade to MK2, root using saferoot and install safestrap 3.72 (the only working recovery for us). Using the remain steps in the tool, you should be able to flash any ROM of your choice from All things ATT thread

[Q] Galaxy S4 Rooting Question

I managed to root my AT&T S4 successfully which is half the battle. I haven't flashed on this device yet but did a few times on my older Droid X. I am thinking of flashing GOOGLE EDITION 4.4.4 that I found on this site under ROMS. Is there like an easy process to flash roms?
Thanks
You need to tell us what firmware version you're on. Different versions have different methods to flash roms.

this root seems alot more complicated than the one for MF3.
The direct root for NC1 is called towelroot. That thread also mentions this.

Turn on your OTA. Within one or two days AT&T will update your phone to 4.4.2 and NC1 firmware. Then you use towelroot .
If the OTA did not happen within two days, you might need to odin the stock MF3 then use the update software function to get OTA.
I turned in the ota and it downloaded the update but it won't update it. It keeps failing and it says my firmware in up to date and u have to wait 23 hours to do it again.

Sometimes, if you have rooted rom, it could happen.
Like I said, wait one or two days to see whether OTA successfully updated. If not you need to odin the stock MF3 to get OTA working..

Please check out this thread.
Sometime OTA does not work if you were rooted. That happened to my while I was with android 2.xx .
So every time I want an OTA, I odin the stock rom.
