I'm having issues with the new UEFI version 3703 released yesterday for my Maximus VIII Hero motherboard installing in Windows 10 Pro x64.
It wob't install in EZ Flash after renaming it M8H.cap and it also won;t install in the UEFI under tools.
In the UEFI (version 3501) in Tools it says it isn't a valid UEFI file.
Itried 4 differnt times between EZ Flash and in the UEFI>Tools to flash to the version 3703 and each time it says it isn't a valid file.
I downloaded the file from the download page for the Maximus VIII Hero yesterday and neither file works.

Yes, we are lucky it didn't install, since it would be pretty close to bricking it for most people ...

I created a support ticket, I guess I'm not the only one but now it is done anyway 🙂

I was wondering on it actually being a Hero Alpha version instead of Hero.
After the first install failed trying both ways, I went back to the download page and it was gone.
I was like o.k., it was buggy.
I rechecked last night and it was there again. The same exact Maximus Alpha one and it didn't work either way.
Hopefully Asus get's their heads out of their asses and fixes it Monday.

I even tried the third way, flashing in DOS, before I understood it was the wrong bios ...

Guys if you select Others as the OS it has the BIOS with a correctly-named file dated today (15th).

Have not tried it yet.

in windows 7 x64

depending on language /us /ro /fr it's either nowhere, or sometimes only in windows 10 x32 (but not x64), sometimes in windows 7 x64 only, etc.. asus not very reliable..
