Strix Z490-E Gaming cannot rollback BIOS from 2004

[hawkhandler]

i have followed all instructions to the T. I am definitely downloading the correct BIOS. I have tried flashback and the BIOS tool and nothing is working. Flashback just fails and the EZ tool tells me that it is not a proper BIOS. please help.

Hi hawkhandler

Have you renamed the bios file to SZ490E.CAP

This should get it to read as a proper bios file.

I have had issues with a z490 Apex and using bios flashback. The first was the manual had the flashback port incorrectly labeled. I had to look at the rear io to find the correct one. Assuming that is not your issue I would try clearing cmos or loading defaults as I have also had it where flashback would not work until I did that.

I also remember seeing one of the later bios versions had a setting to disable being to flash to older bios versions, it can be enabled or disabled. It was under Tools. Not sure if they added that in 2004 as i have not tried it.

Make sure you're pressing the Flashback button and not the BIOS reset.
