hi,
I have an unlocked SGH-I337 with Android 4.2.2 I337UCUAMDL root and revocery,
if I upgrade to version 4.4.2, I lose the unlock??

Yes you will, if you want to be able to flash roms I recommend that you do not take the update

You will not lose sim unlock however you will lose boot loader unlock. Just wanted to clarify that

It's good to know that I won't lose my SIM unlock, I had been worried that it would cause problems for the person I sold my s4 to, it's nice to know I didn't screw them over (T-Mobile user).

No it well not lock it if you root. Once it's unlocked it will remain that way

It has a locked bootloader
Also, you are lucky to still be on MDL firmware, DO NOT update to the MF3 firmware or you will lose ability to root your S4. My advice would be to remove sim card and turn off Wifi (to prevent accidentally updating) then root phone with Motochopper. Once rooted go freeze the update apks to ensure it does not update on you later. MF3 is unrootable as of now so DO NOT update if you want root!
I think you mean MF3. And yes, you have a locked bootloader, you should use this...and he is right do NOT do a update, once you do you lose root, and there is no way back just yet.

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

I am looking for a custom KitKat rom 4.4.2. All the ones I'm finding will not flash successfully. The one I did find was messing up my phone modem (radio) and it was causing dropped calls and EDGE connection problems so I flashed it back to stock. I want a new custom rom without this issue that is rooted with Wifi/tethering.
I have the Samsung Galaxy S4 SGH-I337 model with AT&T.
I appreciate any help it I can get with this!

If you take the time to read like most of us have. You will find out that you can't flash custom rooms if you are on kit kat until devs find exploit, which is going to be very hard.

From what he says you could tell he is either on mk2, nb1 or NC1 which the bootloader is lock down and as most of us know we can only flash Tw roms.

I don't get that from his post. He wants to flash a kk custom rom and he seems to be able to flash roms which tells me he has a custom recovery.
Op, can you tell us what firmware version you're on?

Hello,
Is there a way to downgrade a Samsung Galaxy s4 at&t (SGH-I337) from 4.4 to 4.2. Because I wanted to try doing this http://forum.xda-developers.com/showthread.php?t=2297900 so maybe I would be able to unlock my bootloader and get a recovery, so I change different roms. I looked all over but I have no clue if this is possible.
Thanks!
