    Lesson #1: Please never eeeeeever flash your BIOS through Windows, only ever do it through the BIOS.

    Apparently the G series laptops have a little backdoor coded into their BIOSes to get you back up and running, i'll do a search and see what I find and get back to you

    Thanks man! Actually I was trying to flash through BIOS but apparently it doesn't allow older version. Then I search through this forum to flash older version...that's how I continue to try using WinFlash. I hope my mobo doesn't fry >.<. I teared up the lappy many times already to get RMA.

    OK I FOUND IT!!! yeesh, took me foreeeever, 166 pages of posts is insane, but, a proper search through Google in the Forums, yielded me the answer I have for you and I so hope this works for you, this is what you need to do

    1. Put the USB drive(with BIOS file on it) into a USB port
    2. Press and hold down both the CTRL and Home Keys
    3. Press the power button
    4. Continue to hold down the CTRL and Home keys until you get the BIOS Recovery utility

    Good luck and please let me know how you go

    I was sure it was stickied already, there's supposed to be a "this is important" sub-Forum in the gx5 Forums...but it seems to be gone, luckily I remembered a few keywords to find the right post to list the steps lol.

    I've been able to get this work on the G75VW, but using the original ASUS Windows image which includes the bios file on the C: drive with a *.BIN extension.
    Anyway, if anybody has the original ASUS Windows hard drive image, you can probably skip the USB drive, or if it's not working with the USB drive, try loading the bios file from the hard drive too.
    Below is my modified version of the procedure.

    1. Put the USB drive(with BIOS file on it) into a USB port, or use the original hard drive with ASUS Windows image. If the ASUS Windows image is no longer available, copy the bios file (older versions may work better?) to the C: drive and rename to a *.BIN file (check for the correct name for your model which can be seen by changing the Windows settings to view hidden files, etc.).
    2. Press and hold down both the CTRL and Home Keys
    3. Press the power button
    4. Continue to hold down the CTRL and Home keys until you get the BIOS Recovery utility

    The 2nd half was going to be my next recommendation lol(the BIOS file on the HDD)

    Oh and a note to the OP: don't downgrade your BIOS mate, you'll just end up having to go through all this again, laptops don't have a BIOS Flashback feature...yet lol
