so i took the 4,4.2 ota but ive read that root is not out for it yet, but still only certain recoveries and roms will work.
is there a way i can downgrade then install a recovery to flash an aosp/google play edition 4.4.2 rom?

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

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:

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.

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).

Missed android so I traded my iPhone 5 for an S4. It was already updated and on NC1. Need root for an app that I use at work a lot through the day. Can someone either guide me step-by-step or give me the links to do it? Thanks in advance.
Look in the general forum for index, all things mk2, nb1. Treat nc1 just like nb1. You'll have to down grade, install safestrap and then flash a rooted rom.

Hello, I have just bought a Galaxy S4 i337 unlocked from Amazon. Still on 4.3 and MK2 firmware. I have rooted it and successfully installed Safestrap. Which roms can I flash with it? Also, when I flash a custom rom will I lose the Sim unlock and is there something I can flash to unlock it if so? I will be using this on Straight Talk. I know there are threads about these things but I keep finding different answers. I appreciate any help. Thank you.
First, you won't lose the sim unlock by flashing roms. As far as roms, look in the general forum for index all things mk2, nb1

I originally rooted my i337 s4 using motochopper but then updated to kit kat and of course it wiped my root. Recently I rooted using towel root now I'm rooted again. I would like to flash an official Rom, but not sure the steps I need to go through first.
