    You have to use a jumper first to go in recovery process and follow the steps as indicated.

    First post--not sure if this is the place to ask questions?

    I semi-bricked an Aopen Digital Engine DE65-HA. AMI eufi bios. What I get is drive seek (on Dvd) or USB--but black screen and no boot. I have tried working with the AMI recovery procedure as outlined above (although I have no floppy, using a USB stick), and although it enumerates it on first boot, it does not seem to go back to it

    Coincidentally, while I was banging around the interwebs, I found at least one other person did this as well--like me, he used the version of the bios for the DE65-HAI (which I now know has differences in configuration).

    From this post, I see this other person was skilled enough to remove the bios for reprogramming--and was able to edit a file provided for another (similar) AOpen machine.

    https://forums.mydigitallife.net/threads/need-bios-to-aopen-mp67-d.35286/

    Is my only option to remove the physical bios chip (which seems beyond my ability). Or are there other ways that I can recover this machine. (No bios backup--working when you are tired is always a bad idea!)

    Cheers, Dean

    Hello everyone! Hoping to get confirmation or advice on recovering the BIOS on my Gigabyte Aero 14 (i7700HQ).

    I bricked my laptop by interrupting a BIOS firmware update. It froze during the update and I performed a hard shut-down (stupid, I know). Now I get a black screen when I turn the machine on.

    From what I understand I have an AMI BIOS (P64W7 MOBO) so I should be able to flash it from a USB drive loaded with the .BIN file renamed to AMIBIOS.ROM. Is that correct?

    Do I need to use HP Tools to reformat the USB drive to a bootable drive? Or will just re-formatting it to FAT32 be good enough?

    Any info is greatly appreciated.I'd like to know for sure before trying.

    Thanks!

    @akwon rename bios file to AMIBOOT.ROM. It seems no need of a bootable USB drive. Give feedback asap :)

    extract the .exe file
    try renaming the bios.bin and put it on USB key and test. If no results
    try renaming P64V710.B0E and use same procedure.

    Thanks for the prompt reply @coleoptere2007 !

    I've tried renaming both files and neither seem to work.

    I've sent Gigabyte a support ticket to see if they can provide any documentation or instructions and will pass it on if I hear anything of use.

    Thanks

    It seems you haven't a dual bios so no backup bios. Try booting tapping the END key. The only other thing I can think of is to disassemble the laptop to get to the main battery (disconnect that) and the BIOS battery which is a CR2032 3v coin battery. They are usually encased in some type of black plastic so it's just a matter of removing it from the laptop motherboard and then letting it sit a while so that the board discharges. Put it all back together and hope the BIOS is OK. If not results only solution is to send the laptop for repair.

    @coleoptere2007 thanks for the additional info. I didn't try disconnecting the CMOS battery which may have helped me get into the protected boot block.

    In the end, I found someone locally who was selling the tools to reprogram a BIOS chip and asked if he offered re-flash services. He did it and it's working now. He had to de-solder the BIOS chip and re-flash it on another machine.

    Thanks very much for that Serg008, although sadly it doesn't seem to do anything. Tried holding Fn+R and Fn+B when powering up. Fn+R doesn't actually power up the laptop, but it does flash the power LED and briefly flash the LED on the memory stick.
