    G51JX- need BIOS recovery instructions

    Help!

    I mistakenly flashed a G51JX notebook with the bios of a G51J (no 'x'). It now powers on with no video and never boots.

    Does anybody have instructions for how to prepare a BIOS recovery CD or USB and what the keystroke to enter recovery mode?

    Thanks...

    You can remove a CMOS battery to reset an incorrectly configured BIOS, but unfortunately, ASUS does not provide a method of recovery for flashing an incorrect BIOS to G Series laptops. You'll see it is a source of contention in threads about the BIOS on this forum.

    Unforunately your options are limited to 1) RMA the laptop to ASUS, where they have the tool to overwrite the BIOS with the correct version, or 2) unsolder the BIOS chip from the motherboard and replace it with a new identical BIOS chip.

    I think Drew is probably right that this will require an RMA for repair. But it's worth trying every option for self-repair if you are getting ANY kind of activity when you power it on.

    With a completely bricked BIOS, there are no lights, no beeps, no signs of life whatsoever. IS that the case, or does something seem to be happening, even though you see nothing on the screen?

    Definitely not completely dead. I do get the indicator lights and a few moments of the HD and DVD lights (probably part of their startup).

    Based on various bits of information I had seen on the web about BIOS recovery (Asus and other), I have also tried writing the BIOS files to both USB stick and CD and powering the system on while holding various key combinations:

    Alt+F2 does nothing different
    Ctrl+Home (AMIBIOS standard) actually starts flashing the indicator on the USB stick.

    Before Drew's note, I thought I might be on to something with the Ctrl+Home combo and was wondering if I just needed wither a smaller stick or to rename the BIOS file differently.

    Hey, that's promising! Signs of life!

    Here are the complete steps, as I know them, for the Aptio recovery. I don't know of any G-series owners who have used it successfully, but who knows....



    1. Download the appropriate BIOS, and extract it
    2. Rename the BIOS file to AMIBOOT.ROM, put it on a USB thumbdrive, insert into USB 2.0 port.
    3. Wait at least 15-20 min, or reset the CMOS if at all possible. I would recommend you go to the trouble to do this, even though it's a royal PITA most of the time.
    4. Power up and press CTRL + HOME
    5. The BIOS may reflash from the BIOS file on the USB thumbdrive.


    Alternately, with the BIOS file prepared and inserted in a USB 2.0 port, do a CMOS reset and try all the various BIOS hotkeys (DEL, ESC, F2, F4, etc.) Do a reset before each attempt. Any possible way you can access the BIOS is a possible route to being able to reflash the BIOS.

    Fixed it!

    Success!

    CTRL+HOME is the magic key combo. The problem is the naming of the file.

    On my USB stick, I already had several copies of the correct BIOS under the names G60JXAS.BIN, G60JX.BIN, BIOS.BIN and AMIBOOT.ROM. None worked. On a hunch, I figured that maybe the problem was that it wanted to match the name to what it thought the model was (i.e., the one I wrongly flashed) instead of the correct one. So, I made two more copies: G60JAS.bin and G60J.bin.

    I powered on again with CTRL+HOME. This time the system powered off right after reading the USB drive.

    One more power on with CTRL+HOME and I was greeted with the screen for the "CRISIS FLASH". It went through the flashing steps and powered off. I then powered on regularly which immediately powered off. (This appears to be normal after a BIOS upgrade.) One more power on and I was back in business.

    Thank you all for your help and support.

    Great news!

    So now I will officially dismiss all the reports I've read that the Aptio recovery option doesn't work on Asus notebooks. You've proven that at least one G-series model can use that method.

    or Fix for G51J

    I had Just the opposite problem I have the G51J (I think) with no X and flashed my Bios with the one list on Asus which has the X. Oddly I could not find any product information on the asus site directly but did find a post on another site with the Bios file http://dlsvr04.asus.com/pub/ASUS/nb/G60JAS208.zip . The file does reside on Asus. I put the file on the thumb drive and renamed adding the X in my case and started several time while holding down CTRL+Home and waited about 5 minute between tries. I was estatic to get the Crisis Flash screen.

    Anyone see a product listing for the G51J with no X? if there was i might not have been in this mess. Here I thought the X stood for version A or B or C and so on. To make the matter worse the sticker with the model/version is so badly worn i could hardly read it. LOL.

    Sorry for posting on an old post but this could be very helpful for anyone in the same boat with my system. After all I about crapped my pants when the computer reboot then I had nothing but a black screen and a couple indicator lights.

    So, in the end, what name did he give the bios file ?

    May I know what do you mean by writing to the USB and disk? Is it the same thing as copying the files over?
