I have used google and searched all over XDA. Can someone tell me how to odin my Att S4 with NB1 to tmobile stock firmware? I am just lost at which way to do it.
I am currently running Stock NB1 on my s4. Bootloader is locked.
You can't. Most you can do is downgrade and try to flash a T-Mobile ROM with Safestrap.

Curious why yu'd want to do this?
All u really need to do is Sim unlock it through ATT, pop in yur tmobile sim... and maybe change your APN

Prob because T-Mob is unlocked and has an unlocked bootloader.

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.

I just recently acquire myself a Sprint Galaxy S4. It is not rooted. It is running stock android 4.3 with the L720VPUEMK2 baseband. My question is can I unlock this phone to use on US gsm carriers like Tmobile and AT&T? I don't want to buy any unlock code from ebay because those codes only allow it to unlock to use for overseas. Have I had a choice I would've just bought a Tmobile, AT&T or verizon galaxy s4, but they were too expensive. Can anyone help me?
Pls read next time, anyways no you can't as of right now because only works with mdc or mdl basebands and no way to downgrade right now...mf9 and above you can international unlock tho

Darn it!!! So what you're basically saying is that even if I rooted the phone and use a rom that supports MDC or MDL basebands I still can't unlock it to use on domestic GSM carriers? If that's the case if i'm reading correctly then I guess it's time to put up the phone for sale on Swappa.
I think that because you can't downgrade to MDC/MDL baseband you can't unlock it in domestic GSM carrier at least currently.
The knox in bootloader denied you to downgrade to MDC/MDL baseband.
So either wait to get a solution or sell it.

Some users tell that they can downgrade the baseband easly to MDC/MDL baseband only.
so if you can you can unlock GSM.
Note:downgrade the baseband only ....neither the software nor bootloader.
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.

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).

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 want to know if I flash a stock ROM such as lollipop to my unlocked AT&T phone, would it relock to default network? I unlocked it by purchasing an unlock code from a website.
thanks
No, once you're unlocked it will stay unlocked even if you flash the stock firmware with Odin.
