Welcome to the forum, and thanks for a very valuable contribution! You set a high bar for first post. This is a very important warning for all users of old Thunderbolt 1/2 devices with any motherboard featuring Maple Ridge—not just Asus.The pack (in Google drive and the copy in attach here) includes 3 files ("ProArt-Z690-CREATOR-WIFI-ASUS-9901" in .cab, .cap, .rom). Strangely the version is 9901 (also shown in my BIOS dashboard after flashing). I'm not sure whether I can flash to other BIOS afterwards (during contact, I mentioned that my current BIOS is 1720 with ME 1735. I don't know if the BIOS is a modification of 1720 or not). As far as I tested, the .cap file works no problem with EZ Flash, my Thunderbolt firmware went back to NVM 31, and my Focusrite interface went back alive! For me, I probably would not attempt to update BIOS and ME afterwards (in order to mantain compatibility). Regaring Asus HK, I could not appreciate more for their diligence and helpful service.
Based on this report, you could contact Asus, explain your issue… and hope you'll get a custom NVM-downgrade BIOS for the Z790 ProArt.The other question I have is: what about nvm38 for z790? In my testing, the same buggy mess that we experienced with z690 nvm36 is also present in nvm38. At least for z690 it appears we can downgrade back to nvm31. But what about z790? For those experiencing problems there’s no nvm to downgrade back to…
Or maybe a sorcerer (@Elias64Fr ? @CaseySJ ?) can extract just the code to downgrade to NVM31 from the 9901 BIOS?
