Sabertooth x79 BIOS Flash

[rlintemuth]

I bought my Sabertooth x79 a few years ago and have updated the bios many times with no issues.

Today, I was upgrading it from 4502 to 4608. After the upgrade it asked to reboot, and when it came up, it said that it was in BIOS Recovery mode; please create a file called SABERX79.CAP and put it in a USB Drive and boot from that.

I did so, used the 4608, re-flashed the BIOS; still same error. (it boots up into the EZ BIOS Utility)

I tried to re-apply the 4502, it said that it was old, and I could not do that.

I went online and it said to retrograde your bios, to use the BIOS Flashback button. I am supposed to put the saberx79.cap file on there (old one 4502); insert it into the white circled USB Port; and hold that button for 3 seconds until it starts to flash, at that time, it will downgrade the BIOS.

I can’t get the button to flash, I hold it in for 3 seconds, 4 seconds, 10 seconds, it wont light up.

I can boot from the USB into the BIOS Flash Utility but it will only let me re-apply the 4608 BIOS and not downgrade to the 4502.

Please help; I was reading on an ASUS Forum that they said you can disable that button; well they don’t explain how to disable it or how to re-enable it, which is kind of important if it somehow got disabled.

Thank you

Hi, I'm not aware of any method or need to disable that button. I've never used the USB Flashback method myself, but this guide is pretty self explanatory.

It is crucial that your USB device is formatted to FAT16 or FAT32. NTFS and ExFAT will work for the EZFlash method, but not for the USB Flashback method.

I went to the site and watched the video. If you look at the left video, at around 1:18 second he says you can disable it. http://youtu.be/XI-zGV8SLho

Since mine does not light up at all, but I can still boot from the USB Flash into the EZ Flash utility I am assuming that it is somehow disabled.

I can't find any reference to disabling it in the manual at all. Have you verified the filesystem on your flash drive? It must be formatted to FAT32, with only an MVR (no partition scheme)
