There is a guide to flash official stock ROM which solve most of the problems. If it's soft brick you can try this guide.My computer recognized as HS-USB QDLoader 9008 Port COM. And I checked ur link , and there's nothing about how to unbricked S4 Variants ..
If it's hard brick as u said, you can't do anything else than change ur motherboard.
Giving more infos what is working and what not would help to understand in what situation u are.
