    Use something like 7zip, Winzip or Winrar to extract the files that are inside the EXE file that you tried to flash the BIOS. You are looking for an extracted filename with a BIN, ROM, WPH or FD extension. Rename that file  DH5JVx64.FD It's size should be roughly 9MB. Copy that file onto a FAT32 formatted USB pendrive. It must be the only file on the pendrive. Then insert the pendrive in one of the two USB2 ports. Turn the machine completely off. Then press and hold the FN + ESC keys. Plug in the charger. Then turn the machine on. Don't let go of the FN+ESC keys until you see LED activity on the pendrive. If it fails, try the other USB2 port. If successful, the machine will automatically shut off or reboot itself. Jack E/NJ

    (1) Did you try all the USB ports?
    (2) What is the size of the FD file?
    (3) What was the filename before you renamed it to DH5JVx64.FD

    I have try all the usb port.(both 2.0 usb port on the right side of the laptop)
    I use the isflash.bin file and rename it to DH5JVx64.FD.  The size are about 9.04 mb.

    I think maybe i have taken the wrong bios file. Could you look up for me? I got the isflash.bin file from the temp folder after i run the bios installer using other laptop.

    What other files were extracted? The correct filesize should be about 9MB. You could also try the filename DH5JV113.FD. Also try the USB3 port just in case. Jack E/NJ

    I wouldn't advice advice experimenting with BIOS flashing, as if it is done incorrectly it can brick the system to a point of no recovery.
    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.

    ven98 Agreed but it's already bricked after a failed update. Jack E/NJ

    It is bricked, but there is still possibility to be recovered, but if the flashing fails there is a good chance that the BIOS will be wiped out and in this case no bootable device will be ever detected, therefore it can't be reflashed anymore.

    So what would you suggest differently than the FN+ESC crisis method since it's bricked already? I'm of course assuming the OP wants to avoid the expense of sending it in for an ACER repair. Jack E/NJ

    I think it would be better to just send it to Acer, as they know how to flash the BIOS. If the BIOS is already bricked to a point of no return, then the BIOS chip has to be replaced. I don't know if Acer replaces BIOS chips, but if they don't, then they will charge for motherboard replacement.

    Well, it might be worth getting a repair estimate from the nearest certified ACER Highpoint service region. http://www.highpoint.com.my/servicecentremap.aspx The charge for re-setting a salvageable BIOS ~$100USD in US. A mainboard replacement might be cost nearly as much as a refurbished system. Jack E/NJ

    I was gonna do the same but my flash drive is too big to be FAT32, is it necessary for it to be FAT32?
