[ROM] (Problem with Samsung S4 SGH-I337)

Hello to all developers in the forum. I want desperately your help because i messed up with my phone.
Recently i changed rom to my device. I think that it had the stock firmware from its factory which it was 4.2.2 (i am not so sure).
I updated to 4.3 rom through many difficulties.
The information i can give you is this:
Model Number: SAMSUNG-SGH-I337
Android Version: 4.3
Baseband Version: I337UCUEMK2
Kernel Version: 3.4.0-1921628 KST 2013
Build Number: JSS15J.I337UCUEMK2
I would appreciate any help because my wifi doesn't work as well as the data,the keybord and many other applications. I think that i didnt install the correct kernel. All i did was through odin because i cant install rom through recovery mode. I also cant return to factory mode. PLEASE HELP ME
sammobile.com. didnt work for me!!!

Boot the phone into download to confirm the model #.
Do you see anything about Knox or warranty bit in download mode?

Can't root J530F

Hello!
I have problem rooting my samsung galaxy j530F.
As I have modem version: J530FXXS8CTK1
and version number: J530FXXS8CUB1
[EDIT]: Its Android 9.0
I can't find root file for those versions.
Can I use any alternative version?
I'm new to rooting, so I'm not sure what I can, and what I can't use instead.
Thanks for your time & help
