    Default Re: Gigabyte Z77 D3H BIOS flash failure

    thank you, I was using bios f17b a beta bios on the gigabyte ga-z77mx-d3h when I tried putting the memory frequency to 2000 the result was an endless loop where the board would just reboot over and over again, I tried clearing the cmos with no luck, but once I tried your recovery procedure my board is now fixed, it took a few tries to get it just right, but it flashed from the backup bios and now all is good, thank you so much for sharing this.

    This is a simple and easy method for anyone to try before having to resort to other more difficult methods, or a RMA.

    1. Shut off the power supply using the switch on the back of the PSU, wait 10-15 seconds.
    2. Press and hold the case Power On swtich, then while still holding turn on the power supply from the switch on the rear.
    3. Still holding the case power on switch, the board will start, once it does release the case power on switch and shut off the power supply via the switch on the read of the unit. (Do the latter two parts as quickly as you can once the board starts)
    4. The board will shut down.
    5. Turn the power supply back on using the switch on the rear of the unit.
    6. Turn on the motherboard by pressing the case power on button.

    Once the board starts this time you should see the Gigabyte splash screen, or POST page, then the Auto-Recovery from Dual BIOS will kick in. You will see a checksum error, and then recovery from BACKUP BIOS will begin. Once it is done reboot your machine and enter the BIOS and load optimized defaults then save/apply/reboot back to BIOS.

    Now you are done, and will be using whatever BIOS was in your BACKUP BIOS, From there you can attempt whatever you were previously trying, or update your BIOS to the latest version.

    thank you so much this has saved me again, on another gigabyte motherboard.

    Sorry for resuscitating an old thread, but I wanted to tell you how I resolved the bad BIOS flash/boot loop problem on my Z77-D3H motherboard. It was similar to the solution here, but with a little tweak. I couldn't get my back-up BIOS to kick in and restore the corrupt main BIOS using the turn on/turn off the PSU directions in this thread.

    I continued to search the web and found a little different solution, and it worked perfectly for me. The back-up BIOS kicked in and fixed the main BIOS, and it is now working great, able to get into the BIOS with no problems.

    Keep the case power button depressed for THREE on/off cycles. Then allow the PC to fire up after the 3rd cycle. The back-up BIOS will rewrite your corrupt BIOS. If it works like mine did!

    Here is the post from Overclock:

    "Don't know where I read it, but holding the power button down and then turning the power supply on just for the fans to spin and turning it off 3 times worked.

    Give it time between powering the psu off and on. Make sure the coolers spin every time you do it, otherwise it will not work. Don't let go of the power button at any moment. Only release after 3 times of "rebooting"

    First time i did this it did not work because my PSU saves power or something and apparently 10 seconds of waiting was not enough."

    !!!! I cannot Thank you guys enough, I had the same prob with the same board GA Z77-D3H. Flashing using the @Bios Utility from F18 to F22 was a very bad idea.. Took a couple of goes it re-wrote F18 back in for me...So I got into the Bios and the System is up and running again so thank you Gurus.
    You have saved me Hundreds of Dollars. I didn't need to short pins or take out the battery ( Considering I had already tried that).... Also need to remember if you have taken out the battery... reset your system date and time in windows once your back in, or Internet explorer will block you from even google or Yahoo and tell u there is invalid security certificates. I like it so much I have now joined this Forum..
