Do the downgrade and root, and while on MK2 use the "Possible SIM unlock for MK2" thread.

To go from 4.4.2 to 4.3 is somewhat possible, other downgrades aren't possible. There's a thread titled NB1 DOWNGRADE with the information to do that. Check your baseband first, if you're on NC1 you might need to flash NB1 first.

[Q] Bootloader unlock for SGH-I337Z AIO WIRELESS

Hello all. I am new to this site but I enjoy it a lot and I learned a lot as well from the threads. I got AIO wireless service that has the I337 model galaxy s4. I successfully rooted my phone with Kingo root. After rooting my phone I tried to install a customer recovery on it with no success no matter what I did ( I tried every imaginable scenario). In the process of rooting my phone my kernel got damaged and my Wi-Fi stopped working. I am trying to re flash the phone with custom multi carrier rom but I think that my boot loader is locked and that is the reason I can’t install the recovery. If anyone can guide me in the right direction where I can unlock the boot loader would be amazing. Thank you all in advance
1. This section isn't for AIO wireless but I don't know if there is a section for it.
2. There is currently no way to unlock the boot loader.
3. If you want to restore it back to stock read about it in my signature.

This section is for all I337 variants. He has a different model than the AT&T I337, so that restore tar in your signature won't work and the bootloader may be unlocked for him depending on his carrier's choice.
EDIT: Here is the I337Z stock firmware. http://forum.xda-developers.com/showthread.php?t=2448794
It says they did not get a recovery working, you may be stuck to Safestrap 3.65

4tele, I assume you used the AT&T Safestrap? I was not able to get AT&T Safestrap 3.65, 3.71, or 3.72 to work on my I337Z from Cricket (AIO) with KitKat 4.4.2, build number KOT49H.I337ZTUUBNE2. The app says it installed successfully, but it never seems to activate. Are you on KitKat? If so, what build number?
Anyone know if it's possible to flash the AT&T I337 MF3 firmware on the I337Z then try to unlock the bootloader using the process described below? http://forum.xda-developers.com/showthread.php?t=2387577
I used the AT&T safestap 3.65 but my phone was on MH1 firmware 4.2.2 and it worked, if you are on kitkat probably need to use the latest safestap I guess
guys check this out , maybe one developer decides to take advantage of this and help us out http://www.droid-life.com/2014/08/07/moto-x-bootloader-unlock-qualcomm/

[Q] Rooting 4.3 - MVLUEMK6

Hey fellow XDA members, I have been searching for a way to
root and install a custom recovery on my I337M, but am slightly
confused about this phone, and I don't wanna screw it up.
First off I am on 4.3 - MVLUEMK6. I also have the Knox app.
Am I able to Root using a certain method? I tried Saferoot, but that was a
no go. I have also heard through my searches of "Kingo", which
I'm hoping to try, given it won't turn this S4 into a brick.
Also in the CF-Auto Root Thread, it states near the Downloads,
that AT&T users shouldn't use it, and go figure I'm on Telus. So also a no go..
Can this darn thing be rooted?!?

Thanks very much my good sir, I appreciate your insight on this!
the I337M (jfltecan) is NOT the same as the I337 (jflteatt)
i use a I337M (originally bell), cf auto root works perfect
your phone is the same as mine, use cf auto root and flash via odin on pc, it'll work

[Q] Help on unlocking the AT&T galaxy s4 4.4.2 kitkat

Did you ever find an answer for this? Does RegionLockAway work?
I can't use regionlockaway because it requires root and my phone is not rooted because there is no root for 4.4.2 kit kat on the att variant

Hey. I have the same question about sim unlock for ATT Galaxy S4. My phone is running stock NB1. I did downgrade to MK2 and flashed MDL radio (I got hidden menu *#0011#, but unlock didn't work anyways)...finally I did root and installed RegionLockAway and it didn't work too...so I flashed it back to NB1 and stuck with this question

I tried to downgrade from NB1 to MK2 by this post http://forum.xda-developers.com/showthread.php?t=2663545 and I think MK2 that I got is not exactly same as the original att S4 MK2 (cuz it has multi languages and att version I belive has only 5...idk maybe it's wrong opinion) but I'm sure if you have a stock android 4.3 MK2 you can flash MDL radio, then root it and use RegionLockAway, unlock will work. I did it with Mom's att S4 on stock android 4.3 MK2 before KitKat update.
@denverman, when I downgrade, would this void my Knox warranty and set it to 0x1?

[Q] How Can I Root My GalaxyS4 SGH-1337 4.4.2 | Please Read and Help :)

hey so im a noob right now, this is my first post on here and ive been searching for endless hours looking for an answer.
I have a
Samsung Galaxy S4 AT&T SGH-I337 (got in Arizona, but says Made in Korea)
Firmware: 4.4.3
im trying to find a method that will work for my phone to root it, i have a 32 gb sd card and ive read that other people are not successful with the same phone as me, something like it being "bootlock" by the carrier in this case "AT&T" .
and i have no idea what like nb1 mk2 things are im seriously so lost in ever loop i need helpp lol
but ive looked around for solutions and cant seem to find one.
if there is anyone who can help me root my phone, ill give you any info that you need from my phone,:laugh:
thanks !
There is no direct root method for KitKat. So, you have to do a partial downgrade to MK2(4.3), root and then install a pre-rooted KitKat ROM.

A senior member shouldn't be asking for a step by step or whether they can flash a particular rom. Do your homework

Lollipop rom: you have to wait until Samsung releases one for the AT&T S4.
