I can't seem to update my BIOS past the first release (version 0224). Although the update says "success" (I used the EZ Flash tool within the UEFI BIOS), the system fails to post afterwards (it powers on for 3-5 seconds, then powers back down).
I had an issue months ago trying to update to version 0711, and had to use the BIOS Flashback feature to revert back to the first release. I thought this was just a quirk with that particular bios version and just didn't touch it again.
Today, I tried to upgrade to version 1301, and the same thing happened. I even tried to update the BIOS through the BIOS Flashback feature to bypass the BIOS entirely...still nothing. I became so frustrated that I just downloaded every available BIOS version on the ASUS website and sequentially tried to update to to each one of them. None of them worked, except of course the original release BIOS. I'm believe I'm doing everything correctly: resetting BIOS settings to default beforehand, I even tried clearing the CMOS a few times, it simply refuses to upgrade.
And before you ask, yes, I really want to upgrade the BIOS (to anything) because I believe it is necessary to diagnose an entirely different hardware compatibility issue.
Any help would be appreciated.
