Hello, I've installed tons of custom roms on quite a few different devices before, but this is the first one I've owned with a bootloader that can't be unlocked and I'm still kind of confused as to how all of these workarounds function and what ROMs they're compatible with. I've unlocked the phone and am using it on T-Mobile. It's currently on the MLD KitKat leaked version.
This is possibly wrong, but my understanding is that you are currently unable to install custom ROMs like CM and Omni on this device. So would it be possible to at least flash the stock T-Mobile ROM instead of AT&T? Right now, I have no access to hotspot, which is included in my plan, and I'd also like to use WiFi calling if possible. Has this been done before and is it possible on my firmware?
Thanks in advance for any help; it's greatly appreciated.

You can not flash their stock firmware. You can, however, use Safestrap to flash a ROM from their section, which as long as it is based from the stock firmware will have those features.
I have flashed HYPERDRIVE ROM with T-Mobile compatibility pack and works fine ! Even WiFi calling works!

Thanks, guys. I just got back from a trip and I'll be attempting this now.
Are there any AOSP-type ROMs that will work with this?

Also, if you havent done so, you might want to enable AWS for further compatibility. You will need to use the stock AT&T TW ROM in order to do so.

Since you're using Safestrap, you can't flash a kernel anyways due to the locked bootloader. You should be able to go ahead and flash that.

whether you can put the firmware in i337 from i9505 ?

Click to expand...

What?
Are you asking if you can flash i9505 firmware on to the i337?
If so answer is not until the bootloader is unlocked, then you will likely need to flash a custom i9505 ROM and everything 'should' work but it would not be guaranteed.
Short answer, not yet.
(If you have an AT&T i337 uour bootloader is locked, Canadian i337's are not)
Now that Loki has been released, would it be safe to flash a i9505 custom ROM as long as a Loki'd kernel is flashed immediately afterward?
If that is possible, would anything need to be done for the radios to work properly for mobile data 3g/4g?
Also, I found this thread by searching...it was the only thread that came up, although I thought this would be a big deal for the community being able to flash international ROM's across all devices.

The international ROMs work great as long as you flash an i337 loki'd kernel directly afterwards. The kernels and modems are incompatible, but the international ROMs are absolutely recommended to avoid the AT&T garbage (and get updates)

Radios are not included in ROMs for compatibility reasons.
The kernel needs to have loki patch applied so just grab a kernel from the AT&T threads (TW for stock or touch wiz ROMS and AOSP for CM or AOKP based ROMs.)
I'm on Wanam lite and everything works.....though I get force closes every so often (probably something I've done not the ROM's fault)

What firmware are you running? There's a nice guide on running cross carrier ROMs in the general section, just need to know what build number you're on so you use the right recovery. But yeah, ROMs are cross compatible so you could head into the T-Mobile section and grab something.

Ok, thanks to k1mu's guide here
http://forum.xda-developers.com/showthread.php?t=2565758
I was able to root my phone properly. The key reason to root the phone was no access to tethering. Details for my situation:
Samsung S4, i337, MK2, andriod 4.3 from AT&T. I unlocked it and have been using with Rogers here in Canada but the tethering gives the Mobile data not available/invalid sim error.
I researched for solutions here and on google and all solutions required root, so I rooted the phone using the guide mentioned above. After that I used the method in this link
http://forum.xda-developers.com/showthread.php?t=2535141
However, since I am using non-AT&T sim, this does not work any more. Further I uninstalled all AT&T apps using ES file explorer but still no luck.
Then I figured out and tried other solutions like FoxFi, etc etc.
Then I used the framework file from the thread below which was able to turn the toggle on.
http://forum.xda-developers.com/showthread.php?t=2512981&highlight=at&t
Now I can see the the tethering tuned on. I can also connect to the wifi. however, it does not connect to internet. I think I am still missing some piece. I cannot post in the thread above as it is developers section. But I am lost, there is no further solution that I could find on forum or google. My mobile data works fine, I can turn on the tehter, I can connect to the hotspot, but I cannot connect to internet. It is a phone issue for sure.
I am not sure what to do in this case. Any help will be greatly appreciated.
Edit: I have tried this as well, but it did not work.

Does anyone think flashing with stock ROM will help? does it delete all system files altogether? But the only stock ROMs available are AT&T, so I do not see it helping much. Any ideas?

If there's a tethering mod for the i337m on 4.3, try using that tethering provision instead. Otherwise, you could try flashing a ROM that uses an i337m base, but you can't flash their stock firmware directly.

I have tried that tethering mod (if that means replacing the tethering.odex file in the system)
I don't know what i337m base ROM is, but if it is installing AT&T stock ROM, then won't I be in same situation again?

I337m is the Canadian S4 model, I'm saying to use a tethering method designed for that (the two you posted were for the Verizion and AT&T but not Canadian) or try a TOM based off the Canadian firmware. That way it'll have the file for your specific carrier tethering already in it.

First of all I appreciate your patience in these replies and helping me out.
Here is my next query.
I found this custom ROM based on i337m

This post recommended this ROM

but they also said I need to make sure that the baseband matches. I have MK2. Should I flash that or should I just go ahead and install the ROM as no such info is mentioned in the XDA thread. Also, are there any other changes I should make before installing this new ROM using safestrap?
please let me know

You'll have to look in the All Things MK2 and NB1 thread for install instructions and if it needs a modified updater-script for Safestrap. Also, the latest version is a 4.4.2 ROM so you'll either need to update to KitKat, use the KitKat Magic Toolkit, or use an older version of Goldeneye.
Just got my I337, using with simple mobile. Managed to sim unlock via this method, and was feeling pretty good. I think I had (have?) MK2. So using the stock ROM, it kept on asking to autoupdate. Didn't know if that would screw anything up, so attempted to install a kitkat venom ROM. I now can't get out of safestrap recovery. I'm not sure if the issue was trying to install a kitkat ROM, or if I mistakenly put it in the primary ROM slot. Anyway, I'm on a linux box without any immediate access to windows, so it looks like ODIN is out of the question. Been scouring the forums, but I have a few questions:
1. What are the limitations of the locked bootloader? Not really sure what I'm sidestepping by using a custom recovery. I had read that it limited me to TW ROMS (which is fine by me actually), but I see AOSP and other ROMs posted...
2. What exactly is meant by MK2, NC1, MF3, etc? I understand that they are progressions of SOMETHING, but not sure what--guessing it's the whole AT&T update, including ROM, modem, kernel? And I can't seem to find what exactly the progression is...
3. Is there a ROM that I should try to flash to get me back up and running before I start trying to screw with something else? Like I said, I have access to safestrap 2.71, adb, and an SD card, so I feel like this shouldn't be TOO hard to fix

Well, fixed my problem, though still don't have all the answers to my questions. I couldn't find a way to unbork without odin. Luckily my mom was in town visiting, and had a windows box that I used--I think I would have been hosed otherwise. Anyway, managed to revert to MK2 stock, and then upgrade to Goldeneye kit kat ROM via this method (my baseband is now listed as xxxxxxMLD).
I guess that MLD/NC1/NB1/MK2 are just ROM/radio firmware versions (kernel too, or is that completely unchangeable)? Still don't know the exact order of release, and if anyone could enlighten me a bit as to my other questions, I'd appreciate it...
I'll probably hold off on trying to change anything else until I have reliable access to windoze, unless someone can give me the steps using linux/adb.

The order of firmware versions with Android version - MDB(4.2.x) -> MDL(4.2.x) - > MK2(4.3)->MLD(4.4 leak)->NB1(4.4.x)->NC1(4.4.x)
The bootloader for SGH-I337 was always locked.
1. This means that the stock kernel and recovery cannot be replaced.
2, The bootloader cannot be downgraded.
But, there was a bug in the first 2 releases, that loki exploited and provided a workaround for #1.
When flashing a firmware that contains the bootloader (aboot.mbn), it does a version check. The version check is through a fuse count maintained in the bootloader. MLD and MK2 although are different Android versions, have the same bootloader version. That means you can flash one over the other (go back and forth). The same with NB1 and NC1. But, once you update to NB1, you cannot go back to MK2.
Since the kernel cannot be replaced, all the ROMs we flash have to be compatible with the kernel that we have on the phone. Hence the mention of TW only ROMS. We cannot flash CM/AOSP/AOKP/GPE (most) ROMS. The AOSP ROMS you are seeing are themed TW roms only.

Hey guys, everything I've read has said once you update beyond 4.3 you can never go back down because of knox. I also saw someone mention you actually can downgrade to a custom ROM based on a previous build just not to stock. Can anyone clarify this for me? I'm not worried about breaking my warranty since it's long since expired. I'm on the rooted 5.01 Goldeneye ROM and want to go back to a 4.2 ROM. strictly for tethering purposes

I can't recommend any 4.2 roms as I don't have the phone. Also, I don't think such an old rom will work on an lp modem and bootloader.

You can try but I don't think you will have a functioning phone in that the imei will not be properly displayed which means the phone wouldn't be able to connect to the carrier.
