Thread: Cannot update BIOS on Maximus VI Hero

  1. #1

    Cannot update BIOS on Maximus VI Hero

    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.

    Specs:
    CPU: i7 4770K
    RAM: 2x Corsair Vengeance 4GB
    GPU: Asus GTX 760, EVGA GT 210
    HD: Intel 320 SSD (OS), Samsung Spinpoint F1
    PSU: Seasonic Gold X750 (750W)
    Windows 7 64bit

    I did this numerous times, probably tried to start the computer 10 times after each reflash. Same result.

    Do you mean the Flashback button on the back of the M/B? That's what I've been doing.

    Please explain in detail how you are using the USB BIOS Flashback feature.

    1) Copy correct BIOS to FAT32 formatted USB Drive. Rename to M6H.CAP
    2) Reset BIOS to defaults/Clear CMOS using jumper with PC unplugged (I've tried these steps interchangeably).
    3) Shutdown, plug USB Drive in designated port
    4) Hold button until it starts to blink
    5) When the light stops blinking, power on

    I know I am doing this correctly, because the PC POSTs successfully when I reflash using the first release BIOS, it only fails when I'm using a newer BIOS

    Hello mate

    Please RMA the board and get one that will flash as and when needed you should not be having those kinds of issues.

    I was hoping it wouldn't come down to that, but it seems like that's the only absolute way to fix this.

    Just one more question: Would it be worth it to try and replace the physical BIOS chip? If the actual installation isn't potentially hazardous, I wouldn't mind spending $20 on a new chip if it means I don't have to take the whole system apart and be without computer for a few weeks.

    You can get a new BIOS chip from EBay for a few dollars - less than 20. Give it a try.
