I have I337 with MDL bootloader. Omega 19 (4.3), MK2 GSM modem and MDL LTE modem.
New Omega 20 based on leaked 4.4.2 come.
I read Omega 20 installation notes than it works only with new 4.4.2 bootloder.
Does this means that the only way to install 4.4.2 is wait i337 4.4.2 stock, flash it and use safe strap.
PS
Is LOKI kernel for 4.4.2 TW available?
Was kinda wondering this myself.
I'm on 4.4.2 GE ROM, I assume just flashing a 4.4 ROM updates your bootloader but strangely I don't see any 4.4 TW ROMs in our Dev section yet?
Was hoping somebody has flashed an Intl 4.4 ROM with loki-doki and all was good.

Flashing a rom only updates the system and kernel. The modem, bootloader, and recovery stay intact. Odin packages contain the bootloader and modem. These are all on separate partitions.
The 4.4.2 released was a i9505 rom and only for them. You can be on an older bootloader and flash newer android version roms but you can't do the opposite and say flash a 2.3 rom while you on a 4.0 rom.
Also most people don't want the permanence of being stuck on a leak release and not being able to go back.

Ahh ok, so I really do still have an MDL bootloader huh (even though I've flashed different modems).
But I can switch from a 4.4 GE/CM ROM to any 4.3 or 4.2.2 if I choose, so what do you mean not being able to go back?

MDL was the second update I believe (right after release) for 4.2.2 before the the lock. Once you update the bootloader on these lock bootloaders (even MDL is locked, just has a loki work around) you can't go back. The bootloaders are going to be locked and you wont be able to flash a Odin .tar and go back. You are on there. YOu can flash 4.4 roms on a 4.2.2 bootloader but not a 4.2 rom on a 4.4 bootloader.
Alrighty, so to answer OP's question.
You should be fine to flash new Omega with a wipe of Cache/Davlik/System/Data followed by loki-doki.

not unless he is okay being stuck with a he new bootloader knowing he cant go to another rom unless its a 4.4
Omega (and all custom ROMs) wouldn't include the bootloader as you mentioned in your first reply...

It's true.
I am confused by what I read in the installation Instructions for Omega v20:
Installation:
1. Backup your device (nadroid backup, titanium backup, efs backup ... etc) and save the backup to a safe place.
2. Flash the new bootloder and modems with odin -> I9505XXUFNA1_Bootloader_Modems.tar

I'm on stock android 4.3,rooted with a tripped knox.
Will my bootloader always be 4.3 until I flash official kitkat rom?
Will/can custom KK roms change my bootloader?
Thanks
You have to upgrade bootloader through Odin if you want to flash kk custom ROMs. Custom ROMs doesn't contain bootloader as far as I know.
So yes, your bootloader will be 4.3 until you flash 4.4 with Odin.

There are some custom ROMs that provide links to JUST the bootloader itself, which you can flash by yourself in Odin, without flashing stock ROM.
Thanks for that guys but I don't want to change my bootloader,want to keep it as JB.
I tried a few KK roms and experienced problems with them,was just wondering if it was because I had JB BL.
I need to find a custom rom with JB BL now.................
Thanks
I am trying install Liquidsmooth on ATT S4 on my rooted S4 which has BlackBox right now. How should I proceed with flashing my kernel.
Would just transferring the zip to memory card and then installing them should solve the problem of flashing my kernel?
Also, wanted to know if I should use SafeStrap with multiple ROM slots. As of now I had flashed on stock ROM.
You have a locked boot loader which prevents your kernel from being replaced.
Also, with KitKat Roms, only stock slot works.

I can use Loki for bypassing the bootloader right?
That works only with MDB or MDL boot loader.

So if I downgrade then I would be able to install Liquidsmooth right? Or are there any other steps I would need to perform. If you have any links I would really appreciate it.
Edit:
Sorry, I got confused. I am trying to find my bootloader.

There is no way to get custom recovery other than safestrap if you have MF3 or newer firmware
As stated above if you have MF3 or Newer firmwares you need tobise Safestrap. You cannot downgrade your boot loader to older bootloaders.
If you have the original firmwares MDB or MDL then you can use motochopper and Loki for root and custom recovery and use TWRP/CWM recoveries.
I have to say IF you have MDB or MDL firmwares then the Loki bypass is better. You can run ANY touchwiz or aosp based Roms, flash kernels, flash mods, do anything you want with the phone.
If you have MF3 or newer with Safestrap you are limited to ONLY Touchwiz based Roms, NO CUSTOM KERNELS, and flashing modems and mods

How exactly do I go at getting a recovery now? I've tried installing twrp ,cwm, philz, and safestrap. The I337 I've heard has a locked bootloader though I find this hard to believe for all the custom ROMs. I heard others often experience "System software not authorized by ATT has been found on your phone". Help would not be taken for granted.
If the phone is running a 4.3 or newer bootloader, the bootloader is locked and can only use safestrap to flash custom ROMs.
There are many custom ROMs (there are different versions of the s4 and some of these custom ROMs may be unified builds for the 9505, 9515, i337m, etc.) but only those custom ROMs that can be flashed with safestrap can be flashed to an AT&T s4 with a locked bootloader.

If you're on Android 4.3 or higher then you can only use safe strap and boot touch wiz roms as your bootloader is locked and patched. If you're on Android 4.2.2 or below, you can install TWRP and boot other custom roms like AOSP and Cyanogen mod as the bootloader is locked, but not patched and can take advantage of the loki doki exploit to bypass the lock.

I have 2 phones. One 4.2.2 another 5.0.1. Is there a way I can update with twrp or another custom bootloader and then update to 5.0.1 (not through OTA). Which one should I use? Thank you.
There is no such thing as a custom bootloader for the att s4.

I'm still somewhat interested, even with safestrap. The bootloader cannot be unlocked. OTA update wouldn't be possible as it checks the recovery. I'm interested in ROMs and nandroids.

Is your 5.0.1 one on the OC2 bootloader? It then can only boot touch wiz roms. Golden eye rom and thor rom are good and both can be booted in safe strap which is the only recovery it can use. Your 4.2.2 phone is on the MDL bootloader right? If so use towel root to root it if not already root then install loki doki then install TWRP. After that pick a kernel and boot whatever rom you want...touch wiz, CM, AOSP, etc.

The bootloader lock can only be bypassed with the loki doki tool on the MDL and MDB firmwares. If you're on any other firmware then you're stuck with using safe srap as the bypass exploit was patched in the MK3 bootloader OTA update I believe.
