Best and most easy way is to flash full stock KitKat firmware. Followed by a factory reset and then start over with your CWM and flashing the rom from ladislav.heller
More complicated way :
Download a stock kitkat rom

unzip *.zip
rm -rf SS_DL.dll
tar -xvf *.tar.md5
tar -H ustar -c aboot.mbn sbl1.mbn sbl2.mbn sbl3.mbn tz.mbn > bootloader.tar
md5sum -t bootloader.tar >> bootloader.tar
mv bootloader.tar bootloader.tar.md5

Try to flash it

:fingers-crossed::fingers-crossed: sometimes at late hours i get new ideas . Tomorrow i will try it , now is too late

I tried to preroot / delete knox apps from a system.img.ext4 with make_ext4fs for 4.4.2 . Failed ... system not starting ...
Then i flashed untouched system and rooted after, removed Knox apps , system not booting anymore
I think i don`t delete what i need to
Maybe someone else can point me in a good direction ?

@SilviuMik: I just managed to downgrade from 4.4.2 (Kitkat KNOX tripped) to 4.2.2 with this KNOX removal method but the wifi does'nt work now. Is there any way to downgrade to 4.2.2 with wifi working or is there any JB firmware for I9192 which has the same kitkat bootloader?

When I try to flash other firmwares(without modification) it returns an error:

Flash modem only with Odin 3.10 in "CP" option 2 times or 3 times SAME modem and let your phone reboot . Check if baseband changes

This is what I did in details

my mobile is I9192 samsung galaxy s4 mini duos

first I upgraded it with the RUS 4.4.2 kitkat I9192XXUCNG2_I9192SERCNG2_I9192XXUCNG2_HOME.tar
Then I started to have problems with language and some SD card programs which are essential to me so I want to go back to 4.2.2


First
I flashed the mobile with 4.2.2 "I9192XXUBMK4_I9192SERBMJ3_I9192XXUBMK4_HOME.tar" after removing aboot.mbn sbl1/2/3
the result was no wifi no sound SIM cards not recognized and baseband was unknown

I tried to flash the NON-HLOS + tz.mbn from the same version 4.2.2 three times with the same result "no wifi no sound and baseband was unknown "

Second
Next step was to flash with tz.mbn from the old version 4.2.2 and NON-HLOS from 4.4.2
from the first time sound +SIM resolved and baseband I9192XXUCNG2
But wifi not resolved after three trials

Third
I used NON-HLOS + tz.mbn from the new version 4.4.2
also without benefit

All trials done with Odin 3.09 /Auto reboot and F. Reset time only ticked
all without any benefit
Any suggestions

Experiencing the same thing. No sound , no wifi in JB. Tried flashing even cyanogenmod 11. KNOX is one pain in the a$$. Stuck with kitkat. cant downgrade to JB. sound wifi not working

 

[SilviuMik]

Guess i should stay on JB and don`t try to flash KK yet ( with Knox included )

I think we need to patch the kernel to be able to got stock rom without Knox

 

[SilviuMik]

I did not find something related to Knox name in kernel only TIMA which i disabled but still nogo
Knox 2.0 is in much more places then Knox 1.0 and is more agressive .
And i am not a good coder to understand code in kernel all is intuition. Maybe someone more skilled can do that

 

[fburgos]

I think the solution for you guys is to stick with Samsung kk

Yeah
Because S4 got custom rom with KK TouchWiz based without Knox
Like Omega for example

I think the solution for you guys is to stick with Samsung kk

I'm using CyanogenMod and AOSPA sometimes and I'm very happy with them

 

[SilviuMik]

*smile*

knox:
The new Omega is based on Samsung Android 4.4.2 Kit Kat firmware and it needs the new bootloader to work.
This mean the knox will be triggered and your warranty will be void, more info:

on s4 wanamlite V4 didnt need the knox bootloader to work, also I installed ozcanrom on the same knox free bootloader an worked fine, some video glitch and rare random reboots but it works fine.

I dont want to have that crazy knox bootloader on any device. this will be my last samsung, I'm happy with mine it's knox free
