    I ended up bricking my acer bios when trying to downgrade to a somewhat old version of bios. I had a black screen and nothing was working.

    I tried to recover through the USB pendriver. I tried flashing the USB with the isflash.bin file. I also changed the file name to BIOS.bin, BIOS.fd, C5V01118.fd, C5V01118.bin, isflash.fd and a few others, but with no success.

    I opened the bios with UEFItool and located the name as C5V01X64.fd, but it still did not work. I turn on the fn + esc button, the fan turns very fast, but it does not give a signal.

    Can you upload the BIOS.FD that you're trying to recover with?

    If you don't get a BIOS screen right now, then you have to do a BIOS recovery.
    • Get a small USB stick (2GB or less?) and format as FAT32 or even FAT16.
    • Extract the recovery BIOS.FD (from the archive in my post above) to the USB stick.
    • Plug the USB stick into the laptop (with power off).
    • Hold the FN+ESC key and power on the laptop (according to the steps mentioned by the OP).
    • The fans should kick on high and then it should reflash the BIOS with the BIOS.FD on the USB stick.
    • it should only take a 1-2 minutes, and then either power off or reboot itself.
    Good luck!

    Unfortunately, it looks like you will have to buy a CH341A BIOS programmer and SOIC8 test clip. Then you'll have to find your BIOS chip on the motherboard and reflash it.

    You should be able to use the BIOS.FD that I posted above to use with the programmer software.
