Unfortunately, every method I have tried to downgrade my Rog Strix Z490-G Wifi motherboard from bios 2005 down to BIOS 1003 does not work.
BIOS flashback is not working. Renamed BIOS .CAP file correctly, USB stick formatted FAT32, tried different USB stick, redownloaded BIOS, checked BIOS hash/checksum.. to no avail. Also tried downgrading via Qflash, and I always get a "not a proper BIOS" message. I tried every available BIOS image for the Rog Strix Z490-G Wifi, all the way down to version 0607, and I get the "Not a proper BIOS" message for each one.
As a result, for some reason I am stuck on version 2005, for which ReBAR is not working, as others have noticed as well.
ASUS, please fix bios 2005, or find out why I cannot downgrade my BIOS anymore?

The black screen issue after vbios update and rebar enable is caused by the motherboard bios 2005.

Ok. After further troubleshooting, I was FINALLY able to downgrade to BIOS 1003 using the Flashback tool. For some reason, I had to do a FULL format on the USB stick. No "quick format", despite all being FAT32, would work.
ReBAR is now working as intended on 1003.
I CAN CONFIRM THAT ReBAR IS BROKEN ON BIOS 2005
