    What happened to bios v. 2004?

    What happened to bios v. 2004?

    Hi there,

    I'm stuck on updating my Asus Maximus X Hero bios to the latest version - 2102. I've not had any luck with the built-in Easy Flash tool, or the USB flashback function. If I attempt to use the Easy Flash, I get a message stating I already have the most current bios (not accurate). If I use flashback, an error message informs me that the selected file is "not a proper bios!". USB is formatted correctly in FAT32 and named M10H.CAP appropriately. It's in the root of the drive.

    At some point in the past, I downloaded and upgrade to Bios 2004. This version has since been removed from the ASUS website, and I'm wondering if there were issues with it that could've caused me to become stuck. The most recent bios on the official Asus site is 2003 -- 2004 seems to be gone entirely.


    What can I try to update my BIOS? Can I go backwards to 2003, and then attempt to move to 2102? Any clues or pointers greatly appreciated - thank you!!

    Hey man. Yes you can downgrade your BIOS. It should work EZ flash utility ,but i recommend use bios flashback if your board supports it.

    thank you for the advice! I attempted to use EZ Flash and USB Flashback to move from 2004 -> 2003, and I was unsuccessful. I'm still stuck on 2004 - any ideas?

    well. it has never happened to me. Found this video try this https://www.youtube.com/watch?time_c...&v=DwJS8-GTgRU
    Weird that Bios Flashback doesn't work for you. If you try update from EZ utility, some bios have protection that you cant downgrade it. But biosflashback should be able to go thru
    maybe is possible that bios 2004 was beta and had some bugs and only solution to downgrade it or upgrade is use some third-party tool. well in this situations i'm glad i have board with dual-bios

    Hi,

    I'm happy to report I was able to flash my BIOS successfully using the bootable DOS. Thank you so much for the help!
