On X-1 Extreme... Current bios = 1.18. Using Vantage to update to latest bios gave the message "secure flash authentication failed". I rebooted and it's still at 1.18 (by entering bios settings) but Vantage reports that the bios update was completed. It still shows 1.18 at the bottom of Vantage. How do I get it to update to 1.19?
I downloaded the update: n2euj11w and ran WINUPTP64.EXE and get the same failed message.... NOW WHAT?

It could be in the BIOS settings.
Note: I am looking a BIOS from a different system, but I believe it may be similar in yours as well.
Launch Setup to enter BIOS, Go to the Security section, and see if there is a section called UEFI BIOS Update Option
If so, open that section and check to make sure that "Flash BIOS Updating by End-Users" is Enabled, and Disable "Secure RollBack Prevention".
Try to update the BIOS again, and if successful, you may want to re-enable Secure RollBack Prevention" at some point.
Best of luck,

I was able to create a bootable USB memory stick and update BIOS using that. I'm now at 1.19.
Thanks JDGillis, I just checked UEFI BIOS Update Options and all were Enabled.
I had no problems when I udpated to 1.18. Strange...
