Z370M Pro4 - BIOS File Does Not Support This Model

I'm having a beast of a time upgrading the BIOS on my Z370M Pro4.

I've tried the internet flash option in the BIOS utility but no matter what region I select I get an error that the utility can't connect to the Internet even though I have no Internet issues in Windows

I've tried the Window utility for versions 1.30, 1.50 and 1.70 and all three give me the message that The BIOS File Does Not Support This Model.  I most certainly have downloaded the versions found in the Z370M Pro4 section

Currently my BIOS says that it's version 1.0. 

Any suggestions?  Anyone else having problems?

NM,

Look again at the DL link in your post. See an Z370M in there?

My second post.

His "The BIOS File Does Not Support This Model"?

They've been trying to flash the wrong BIOS.
