ThunderboltEx4 NVM31 downgrade tool

[Pacecar]

Hi there - Asus recently had a tool that would allow the downgrade of firmware on their ThunderboldEx4 card from NVM36 to NVM31 to support Thunderbolt 2 devices, however the tool is no longer available. Would anyone kindly have a link to the tool?

Thank you!

Hello @carlitoarticulo 
I’ve also sent you the relevant information.
Kindly check your inbox at your convenience, and ensure that your connected Thunderbolt device is Thunderbolt 1 or 2.

Thank you.

Please help! I need this for my board too!

I would also desperately need the downgrade tool. The ASUS updater had automatically updated the BIOS of my ProArt B550 after not having used it for a year. Now I cannot use any of my Thunderbolt 2 studio gear! Please help!

I think the reason they have taken it down is that it no longer works with the latest BIOS. This is the case on my Dark Hero with latest BIOS anyway

Seems I have a choice of letting my i9 slowly die, or abandoning my £2K audio interface 😞

Please, could you DM me the downgrade tool? I have no intention to use the latest BIOS so this should work for me. 

Really would appreciate your help!
