Bootloader / Downgrade question (Self-Solved[SELF-FIVE!])

Update: I am trying to address the bootloader version issue by flashing to the most current stock rom MVLUFNI2, fingers crossed.
Update 2: First boot screen on stock 4.4, sound plays through speakers...solved.
I have two stupid questions. Background:
SGH-I337M (Telus), rooted with Odin and CF Autoroot.
Stupid question #1 To return all the way back to unrooted/counter=0/warranty status, do I need to find more than a stock rom? eg. a stock bootloader or kernel, etc. packaged separately?
I decided to try Liquidsmooth 4.4 on for size. I don't know what version of Android I was running...oops. LiquidSmooth bootlooped, so I grabbed SlimKat 4.4. It booted and went to homescreen but with no sound from any source, no mic, and no phone calls in or out on top of running like garbage. Got frustrated, grabbed official stock rom (4.2.2!) and flashed it. It has the same issues I was experiencing in SlimKat. I have tried several roms, formats, and factory resets as well as every other solution I can find online to no avail.
Stupid question #2 I've come to understand that you can't downgrade from kitkat to jb due to bootloader changes; are the issues I'm describing something you would expect to see if you had?
Oh yeah, I haven't done any recovery/rom playing around in about two years and I was rusty as hell. When i flashed from original rom I did it DIRTY...no reset/format at all, and using ROM Manager from the phone's interface, then realizing when I rebooted that I hadn't actually installed CWM and the phone was booting into stock recovery. I've used CWM or Odin for every flash since, but I'm afraid this problem may be complex..... thanks in advance for the answers =)

Last time I returned to stock I had major problems on first Boot. Lost patience and pulled the battery. Booted to stock recovery and did a factory reset. Seemed that the flash in Odin did not remove ancient data. Factory reset did the trick.

Don't know if you tried it and if it you do any difference if not.

Hi All,
I have a I337 on stock 4.2.2 with the MF3 baseband. I would like to use this phone with T-Mobile.
Can I simply follow the steps in this thread to get root and unlock the phone?
I would also like to install a custom rom, do I need to install safestrap after I have rooted the phone or do I have other options?
Thanks.

It should work, but you might try saferoot to root. You will have to use safestrap to flash roms

Are you referring to this? I don't see MF3 listed for the i337 but this looks like a good option if it will work.

Yes, I would try it. I'd also try towel root. not sure if either will work but they won't mess anything up if they don't work, they'll just fail, and it easier than messing around with the sd card

Thanks for your help so far, everything has gone perfectly. I am now rooted and unlocked. So for hopefully my last set of stupid questions, I am wanting to install the Goldeneye Rom.
1. Which version of safestrap do I need to use? This one appears to be the newest but I am not on KitKat so do I need to upgrade first? If so, how do I upgrade to KitKat without losing root/unlocked?
2. On the Goldeneye Safestrap Install Instruction Page it lists 4 different ATT modules but not MF3. Does this mean that the rom doesn't support MF3 or that I have to be on one of the listed modules basebands?

now that you're sim unlocked you'll probably want to Odin to nb1, see the general forum, then ota to nc1. You'll have to re-root using towel root. Then flash safestrap 3.75 then your rom.

I can go straight from MF3 to NB1 using the I337UCUFNB1_4.4_Stock_Odin_tar file in the link you posted? I don't have to go to MK2 or anything else first?

no, you can go straight to nb1 in Odin. It will wipe your device so backup anything on your internal sd card

I bought my son an Att Galaxy S4 and I rooted it and I want to put a ROM on it before I give it to him. Knox has supposedly been disabled but I don't want to brick the phone. I have installed roms and recoveries on numerous older phones so I have a small bit of experience. In the past I have always flashed a recovery in Odin but when I downloaded a recovery for this phone is was a .IMG file which doesn't work in Odin.

If you have done this on an Att Galaxy S4 I would appreciate some help, thanks.

If you are running any other firmware besides MDB or MDL, then you have to use safe strap for custom ROMS and recovery due to the locked bootloader.

You can only bypass the locked bootloader by using LOKI doki. In order to use LOKI doki you need to be on the MDB or MDL firmware. The NC1, NB1, MK2, and Nl1 firmwares are LOKI patched and will only work with Safe Strap.

Hey guys, I've just gotten my wife a used S4. It's running goldeneye but I'm not sure what version I'm on. How do I know if I need to use loki or safestrap? The baseband version is 1337UCUFMLD.

Thank you i decided to stay with nb1 and install safe trap also safe trap doesnt work unless you install selinux mode changer and set it to second option theb safetrap will work by the reboot button turning on. Thank you guys for the help

Hellos,
I'm a noob and recently rooted and installed a custom recovery my S4 in attempt to install Cyanogenmod. This was after the last update by At&t and the bootloader doesnt let the recovery (TWRP) boot. This was before I heard that Att added a boot loader. I have tried many methods to return to stock but all have failed because of the bootloader. Any way to remove and return to stock or perhaps unlock the bootloader?
