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

on top of stock rom, my stock rom was JeallyBean 4.2.2 i337 mf3 not mdl and i read there are no mf3 files for odin
So i managed to fix this problem just by downloading stock rom for my phone and flashing with safestrap: Galaxy S4 rooted Stock ROM AT&T SGH-i337 MF3 (i found that on google)
The rom i downloader is rooted. and it said to install Loki after finishing flashing rom but i managed not to.
after you finished flashing you need to install also: jflteatt-MF3-modules(attachment) : this will make your wifi to work.
Every thing i just said, worked for me! do this at your own risk! im not responsible for any damages!!!
Wait what if you flash MDL with safestrap, and use goo.im for TWRP? It could possibly brick but just an idea.

It wouldn't. The bootloader is still MF3 no matter what you do to the system, and so it will still be locked with no way to bypass it.
Hello,
I just rooted my S4 ATT I337 followed this threat: http://forum.xda-developers.com/showthread.php?t=2565758
I'm currently have my phone on MK2 build. Anyone know how I flash my phone with Odin so I can install CM10?
You cannot. We don't have a custom recovery. We have locked bootloaders. All you can do is root.

hmmm, so we can not get 4.4 kitkat? are the other 4.2.2 roms much better?
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?
