So after 3703 appeared on ASUS Z170-A BIOS download page today, I updated to it - it still doesn't solve the problem with Error 8719. MEUpdateTool doesn't update ME firmware. Intel-SA-00086 Detection Tool reports that the system is vulnerable, same result with running FWUpdLcl64.exe -f ME.bin, Intel MEInfo 18.104.22.16825 also reports Local FWUpdate as Disabled.
Is ASUS going to fix this problem or not? Or am I stuck with a vulnerable firmware on my motherboard, when it is a fairly recent model?
Furthermore, they should fix their MEUpdateTool because it misleads users that their system was updated and, therefore, safe:
When in fact, it wasn't updated and is still vulnerable:
Does this means that this new bioses that are being released with the updated microcode doesn't come with the ME update?
@Broheim DId you tried to see if Local FWUpdate was set to ENABLE/DISABLE using MEInfo Tool ?
To downgrade your bios, you can try with Winflash with the command prompt using Winflash /nodate.
I don't have the same board (Sabertooth Z170 Mk1), but I was able to flash the new ME using a 3xxx Asus bios (3401)
It is possible to update the firmware first to 11.7.
