[Q] Loki + Roms from other S4 variants

So, if I'm running an auto-Loki recovery, like OUDHS, what is the correct process to flash a rom from, say, the Sprint GS4 variant?
For example, the Sprint S4 has a ParanoidAndroid build. What would I need to do with my ATT S4 & OUDHS recovery to properly flash that rom? Is that even how it works?

I am not a dev so I may be wrong but remember that the Sprint is based on CDMA , not GSM. I would not flash a Sprint based Rom unless a dev had modified it.

So, you're suggesting that with any Snapdragon-based S4, I can just flash the rom, then flash a Loki'd kernel, and I'm good? Except for maybe adding the ATT APN?

Even with roms for the Sprint S4? Surely that would cause a problem.

While the S3 had the att fix, there was a problem with gps for many people after flashing sprint or verizon based roms. I lost my gps and had reset the nv to get it back. There was a fix for this with the S3, but I don't know if it works with the S4.

[Q] Would I be able to use a I9505 rom for a I337m S4?

Hello,
Just as the title suggests I am curious if I am able to use a I9505 rom on a I337m S4? It seems that theoretically it would work considering the hardware is the exact same (correct me if I'm wrong) but I'm just curious if it were to work could I potentially run into issues with the baseband being different? Sorry I'm really new to this whole flashing thing
Any help would be greatly appreciated,
PhantomMango

Yes. I used foxhound for a while on my i337. I had to use an auto-loki recovery but you won't need to if you have an i337m. Just make a backup and don't flash i9500 roms.

Really? I had a whole thread on this question lol well atleast someone answered it somewhere else. I had the impression you could not since i tried to flash a rom from the i9505 section and it did not boot after that. I had to use one from here , It didnt make much sense why they wouldnt be compatible in the first place. So you can use roms that are from i9505?? Maybe I had a bad flash ??

Did you flash a kernel from here right after flashing the rom? I would download a kernel and the loki-doki zip. Try the kernel first and if it doesn't boot, try Loki-doki zip then boot. Like I said, I used foxhound for about a month not one issue.

Wow thanks for the replies everyone!
But I just have some more questions, when choosing a custom ROM do they already come with a kernel or do I have to "supply" my own that made for my is particular carrier? And I assume it would just be trial and error to find out which kernels work best with a particular ROM. Or should I just use the custom Kernel that the ROM developer suggests since I337m has an unlocked bootloader.
Thanks,

You may have run into these issues if you have the ATT i337 -- as posters above have said, you'll need to apply the loki patch or otherwise your device won't boot.
i337M (Canadian) users, to my understanding, should be able to flash i9505 ROMs as is, given the unlocked bootloader.

I believe some stock kernels will work, not sure if all will. I used Omega on my i337m with KTs T-Mobile Kernel and it worked really well.

Thanks for the feedback so far,
But I just want to be 100% sure that I am able to flash this ROM on my phone after rooting. I am wanting to flash this ROM using this guide so can somebody again provide reassurance to me that this would work on my I337m phone and not brick it. I just don't want to cause any confusion with what I meant by custom ROM (In this case AOSP).
Thanks,
PhantomMango

I wouldn't follow guides outside of XDA. There are plenty here that have been proven to work. Read the ROM's OP and first/last 20 pages at least. Your're bootloader is unlocked so no loki-doki needed.
For Canadian, you want the TMO kernel from here--the TW Jellybean 4.3 one and follow flash instructions in KT's OP there

Always Nandroid before flashing new things and have sdcard backups on pc as well as the Nandroid

[Q] Galaxy S4 i337/i337m/i9505 ROM compatiblity

Just wondering about the safety of installing roms made for the i337 on the i337m or i9505. I recall reading a big thread on XDA talking about this earlier. Thanks.

I've got the i337m and I've never had a issue. On a i9505g Rom now. You can flash anything to anything as long as bootloader isn't locked

The leak won't work for you because it's a full ODIN package. It's signed for I337 and not the I337M, and is not in a flashable zip form. Even if you could use it, you'd have a locked bootloader afterwards and never have recovery again. You'll have to use some other 4.4.2 ROM, maybe check the i9505 development section for a recovery flashable one.

Thx so much. It's clearer now for me; it is indeed a tar file signed for I337 I was wrongly thinking that since I337M and I337 both share the same hardware rom compatibility might be possible, but I guess the AT&T factor plays the game otherwise. I'll check what's cooking in i9505 thread.
So, If I understand you correctly, an i9505 flashable zip, like wamalite for example, would work for i337m, is that so?

Yes. Any ROM in a flashable zip for any variant of the S4 except the i9500 (exynos model) will work on your device. I9505 are the easiest to get working, some other variant ROMs may need tweaking to work well. There's a thread about running other carrier ROMs in the general section.

last, would there be any knox issues if I flashed I9505 roms or do I have to simply remove knox? I also read that someone who flashed I9505 rom onto his I337m tulred his device to I9505 as well; is that "normal"

I don't know much about how knox affects custom recovery or if you can flash without tripping it. I know for sure it won't stop anything but would just simply void warranty. If you flash an I9505 ROM then because of the build.prop it will tell you it's an I9505, but it's still an I337M, you can't like use the i9505 ODIN files or anything just because you have an i9505 rom.

Actually I am really not familiar with all the terms (MK2, Safestrap recovery etc. Is MK2 the Baseband version? In mine it says I337UCUAMDL).
I have been trying to search and learn how to do this properly and what I exactly need, with no great success.
I did find this:
http://androidxda.net/install-android-4-4-2-kitkat-i337ucufnb1-on-att-galaxy-s4-sgh-i337/
Is it what I need (upgrading to KitKat)? And do I have to ROOT before (I haven't done it in the past, and actually don't know how).

Only ir works and with certain apps

I would say stick with tw if you use the tw features try @iB4STi tw Roms with @Alucard24 touchwiz kernel what I used for the longest time using cm12 unofficial ATM but if you don't care about tw features then liquid smooth, carbon rom

Thanks! One last question, I think.
The up to date ROMs here are mostly for safestrap, if it doesn't specify that it works for our phone (bell s4) I probably should not flash it?
Some do say it can be flashed with non-safestrap(twrp) but we need to flash our carriers kernel after.
How can we make a back up of it (the kernel that I have on my phone right now) and make it flashable from twrp?
Thanks again!!

You can't or at least I don't know how... But there are touch wiz kernel that will work alucard or ktoonsez have best kernel for our phone @s3nr1
Also check in 19505 s4 thread thats where I find all my Roms that are aosp for touch wiz look in i337m/att s4 section.

Also you can backup your stock rom with twrp and flash what ever you want then restore the stock back up after to go back
