Well to be fair TBTFlash.exe asked for the custom firmware, so I simply uploaded the modified firmware and it flashed the fw. Don't know if anything else is required
I wanna point out that I repeated the same procedure with a original Titan Ridge 2.0 card and the flash worked, therefore I have no idea on why it doesn't work this time... I think the F9I BIOS is the culprit. Eventually what's the BIOS version I should flash to make the TB3 work?
Please run IORegistryExplorer, scroll (not search) down to RP05, and post a screenshot. That will give us a good sense of what happened.
This screenshot shows that Thunderbolt Bus is not enabled (firmware did not change). Does your GC-Titan Ridge look the same?

yeah. at this point how can the BIOS interfere with the TB3 card if the TB3 card has its own firmware?The screenshots in this post show a fully rendered Thunderbolt Bus:

** Gigabyte Z490 Vision D: Thunderbolt Firmware Flashed ** Because of the similarities between Z390 Designare and Z490 Vision D it was very straightforward to read, modify, and flash the Thunderbolt firmware. I followed the Supplemental Procedure and was able to read and flash the chip in the...
I don’t know what you mean. BIOS does not interfere with Thunderbolt. Even on-board Thunderbolt has its own firmware chip (it does not use BIOS chip).
