Downgrading 4.4 to 4.2 or 4.3 on I9505?

I'm already aware of the Knox bootloader stuff, but with the S4 Mini there's a baseband version of the firmware that runs 4.2, but has a Kitkat bootloader. I was able to thus successfully downgrade my S4 mini from Kitkat to Jelly Bean.
That said, is anyone aware of something similar for the S4? A regional version of the ROM with Jelly Bean, but the KitKat bootloader?

Downgrading S4 i337 from 4.4.2 (NB1) to 4.2.2 (MDL) using Odin

Hello,
I have S4 i337 and it is on 4.4.2 (NB1) and tried to downgrade it to 4.2.2 (MDL) using Odin but it fails. I want to know what might be the reason behind this failure. Help me resolve the issue.
Does the phone have a locked bootloader?
Up UP UP, wish people helping to unlock bootloader
Once you're on Android 4.3 or higher you cannot downgrade your bootloader (with the exception of NB1 I think it is) to an older version as Samsung has added in extra protections against such.

Is there anyways to unlock bootloader of shv-e330s?

I want to downgrade to 4.2.2 but I can't find the PDA in my phone only the 4.4.2 has the exact PDA in my phone, I was downloading some stock firmware on sammobile and Samsung updates but still only 4.4.2 has exact to my phone and there is no 4.2.2 available for my phone, so I've read some forums that GT i9506 is bootloader unlocked and the i9506 and I've heard some people that shv -e330s is same with i9506. And other variants of s4 is bootloader locked. So is it possible that I can downgrade 4.2.2 from 4.4.2? My s4 is shv-e330s
This was my phone firmware:
