It has been my understanding that in order for something to be installed in Odin, whatever it is needed to be signed by Samsung. If that's the case, how are there stock customized ROMs being made? There's one for vzw, tmob, and Sprint S7.
Because you can flash roms with FlashFire

AT&T S4 with 4.2.2 MDL. I rooted it way back when. I have CWM recovery installed. No AT&T Updates have happened because they always fail At the same time what are my options for getting 4.3 or for that matter when 4.4 comes out?
I have bloatware still. Use root for backups and a few other root required apps. I've run custom roms before when I was on my HTC Evo 3D. If I install a custom rom will I loose my current root / status?

I would use these as starting points because they're modded slightly and if you want more, explore other roms.
Make sure you update your recovery to avoid any errors in flashing. You can also flash to the latest radio and revert if it doesn't work for you.
You won't lose root. You already have recovery, so you can always get it back.
There are 4.3 custom roms out there, there are people who want an S4 that came with MDL. I'd flash a custom 4.3 rom. We can even ugrade (flash) our modems to MF3, MJ5, MJ6 and flash back to MDL without ruining the phone like those who took the upgrades prior to root and got screwed by Samsung.
Do some research like above and for gods sake dont unroot your phone and take any OTA updates or you will regret it.
Just my advice.
i'm AOKP on my Nexus 4 atm. I've heard that even if you do OTA for custom rom or flash a new custom rom like cyangomod mod or another AOKP rom, the baseband WOULD NOT be updated but rather it keeps the baseband that your phone originally came with, i was told custom roms can't change your baseband.
However, i was also told that installing a new stock rom like going from stock 4.3 to 4.4 would update your baseband. Or if you're on stock 4.3 and do an OTA upgrade to 4.4, it would also update your band.
so custom roms can't update or change your baseband via OTA or flashes and Stock roms can?
Custom roms can change your baseband, its just that they choose not to most (if not all) of the time. In other words, they have the potential to do it, but they dont.
Its the same with ota's or stock roms. They can change the baseband...sometimes they do, and sometimes they don't. It all depends on what has been included in the .zip and what the edify script tells the recovery to do.
It is common practice not to change radio/baseband with a custom ROM as flashing firmware can be dangerous and shouldn't be done unless needed.
To top it off flashing any firmware through recovery is the least safe way to do it, granted that is how OEMS will do OTAs which often come with new firmware.
So to answer your question you will pretty much never get a new radio packaged with a custom ROM, but when there is an ota that comes with a new radio you will.

I currently have AT&T stock (I used to have a custom ROM then had to flash to stock ROM to be able to flash to another custom ROM--however, I accidentally flashed a newer version of the AT&T stock ROM which locked my bootloader and I could no longer flash to a custom ROM). I updated my AT&T stock ROM recently and now my back/menu buttons don't work, so I want to see if I can flash to a custom ROM now.
I don't remember the procedure to flash a custom ROM--do I first need to get root in order to unlock the bootloader to be able to flash ROMs (i.e. if I have root then I am guaranteed to be able to unlock bootloader in order to flash ROM)? Is the baseband version the only thing that determines whether I can unlock the bootloader and then be able to flash ROMs?
I currently have OK2 as broadband version and checked one of the stickied threads which said this:
" ROOT
OK2 -- No direct root method. Must Odin OC4 kernel, use Kingroot, then Odin OK2 kernel back."
Does that mean what I have to do is use Odin to get OC4 kernel, then use Kingroot, then Odin OK2 kernel and then I will be able to have root, which means I can then unlock my bootloader and be able to flash to ANY ROM (not just TouchWiz-based ROMs)? Is there anything else I need to consider or is this 100% foolproof? In the future, what should I be careful of in order to prevent getting my bootloader locked again--just that I don't flash a stock (AT&T) ROM that is known to lock back the bootloader?
Thank you all!
There's no way to unlock the bootloader if you have updated your device to the lastest firmware version. The only thing you can do is flash SafeStrap and use Stock Kernel Based ROMs which are compatible with Safestrap.
As regards to the procedure of rooting an OK2 firmware, I'm afraid I won't be able to help you.
Have a happy new year.

I was just about to sit down and flash a stock ROM. Can you explain what you mean by this? Did you flash OK2 and it caused you a problem?

It was a while ago but I used to have I believe an MDL broadband version which meant I could flash any ROM available. I tried a different ROM, didn't like it, then decided to flash back to the stock ROM but accidentally flashed a newer version of it, which meant that my bootloader is now locked. With a locked bootloader, apparently I can only flash to a newer stock ROM (not other ROMs like Cyanogenmod) via Safestrap.
I think if you don't have the MDL broadband version you shouldn't worry about it anyway because it is locked and you will only be limited to flashing stock ROMs.
Slight correction
The previous entry is not entirely correct. Like the OP, I was originally on an unlocked bootloader on my i337. I'd purchased my i337 on the first day and eschewed OTA updates. I wanted to try a touchwiz based ROM, Hyperdrive, and in doing so I recall flashing the stock NB1 firmware. Every firmware beginning with NB1 has a locked bootloader and there has been no progress for more than a year in unlocking the bootloader again. This can limit you to either stock ROMs OR other touchwiz based ROMs like Hyperdrive. I love the Hyperdrive ROM (now on release 21) but its developer has moved on to a newer phone, so it's stuck at Android 4.4.2 and no one has picked up the project in many months. There are several other touchwiz based ROMs for the i337 version of the S4 which I have also tried but I prefer Hyperdrive's myriad customization, even without proper patching. I'll be moving on soon to the Nexus 6P as my daily driver, but would very much like to keep my S4 up to date with a custom ROM. Given the number of people that have been in this same situation, where a newer stock ROM from AT&T locked a previously unlocked bootloader, it's been surprising that the issues have not been overcome on a phone as popular as the Galaxy S4 was and continues to be. I've seen unlocked versions of the S4 selling for just under $400 in the last week of 2015.
Use the desktop version of Kingoroot to root and use Super su and update the binary. Don't forget to hit thanks if this helped.
The bootloader for the at&t s4 was never unlocked. The MDL bootloader had a flaw in it that allowed you to use LOKI which is a lock bypass, not a way to unlock the bootloader.
My Dad recently got a Galaxy S4 on Sprint for work, and he wants to put stock Android on it. Is it possible to put the latest GPE ROM on this phone? And if so, is there a guide? I looked around but could only find instructions for Jellybean.
Root it, flash a custom recovery and flash the rom.
Or skip the rooting and flash a custom recovery directly, then flash the rom. Roms usually come pre-rooted.
if you want pure Android but also the latest look at AOSP roms too...
My son's ATT GS5 is currently on stock rom OF3 and want to experiment flashing custom rom. Can someone point us into the right direction.
Here's my understanding, need to flash recovery (where can I find instructions) and then rom. Also, do I need root in order to do all this?
Thanks.
Unfortunately the AT&T G900A has a locked bootloader so custom roms are extremely limited. There are also no custom recoveries available for the G900A except safestrap, but even then it cannot do much.
