Unhappy [Q] SHV-E330S Baseband and IMEI fix?

Hi,
I'm desperately looking for a way to restore my phone functionality.
Model Number is Galaxy 4 SHV-E330S!
I have been trying to root my phone now for over a week, I have managed to remove all firmware, and then restore it as there doesn't seem to be anything that works.

I now have the original firmware, however, there's no recognition of 'phone' software:

No usim detected;
Baseband version: Unknown
IMEI: Null/Null

I cannot upgrade most apps, as that seems to be blocked as well. Flashed stock ROM as many times as possible via Odin and Pilz software, repartitioned device, and still nothing!

PLEASE PLEASE WILL SOME ANGEL SWOOP DOWN AND HELP ME GET MY PHONE WORKING AGAIN?
