Need Help - G73JW-3DE VBIOS

Hello Guys!

After a VBIOS Flash attempt gone very bad, my G73JW-3DE doesn't display anything anymore.

I can still boot into Windows though and can execute nvflash there. I've tried several VBIOSes I found on the web, but none so far has brought back display output.

As an additional problem, the G73 does not seem to be able to boot from USB, even though I try to bring up the boot menu by hitting ESC. Specifically, USB ports seem to be powered only after Windows starts, as their LEDs are dead before. So, I can't seem to boot to a DOS environment.

My last attempt at salvage before I have to RMA my notebook (which I would like to avoid, living in Europe, where the density of service centers is pretty low) would be to try to reflash with an original G73JW-3DE VBIOS which I would need in .ROM format.

If anyone of you would be so kind as to provide me such a BIOS file, I would be more than happy and grateful.

Thanks in advance for any help provided!

 

Not sure if the 3DE has a technically different 460m card, here's a thread with a couple vbios dumps: http://forum.notebookreview.com/asus-gaming-notebook-forum/584145-looking-g53jw-vbios.html

Make sure you aren't trying to boot off of the blue usb3 port, the other usb ports should work fine for booting.

 

Always backup your original vbios and NEVER use windows to flash it...if you cant display POST on your lcd use an external monitor.
As the vbios, any G53JW bios should do.

 

Yes, I know I've been reckless for not backing up my VBIOS before. Will try the BIOSes posted in the thread you pointed me to, thank you.

As for the USB boot, I reckon that the USB 3.0 port shouldn't work, but in fact, none of the others works as well. They seem to be powered only after the computer boots into Windows (after which they work fine)

Could this be because I disabled USB legacy support in BIOS? Any idea how else to boot to a DOS environment? Tried the DVD drive also, but to no avail.

I tried the VBios provided in the G53 thread, but it did not work out either. What's strange, when I set NVFLASH to give audible feedback while flashing, ît does tick for a few seconds, then finishes. The time is so brief that I'm not sure it is only ticking while it's erasing the old BIOS and not writing the new one.

So my only option left seems to be an attempt to reflash under DOS, for which I will have to solve the USB boot problem first - any ideas there?

 

Enable USB legacy in bios, or reset the bios to default settings. Dont use the 3.0 usb port, use the standard 2.0.
About the mistake of not backing up the vbios, keep in mind that vbios flashing is not a thing to be understimated.
It can put your laptop in unusable state, and RMA wouldnt repair it since its a proof of tampering.
Vbios flashing should be taken with a good knowledge and necessary tools to revert back to stock vbios if something goes wrong.

 

Question, now that you peaked my curiosity. how would one backup a Vbios?

 

Can anyone tell me the exact order of keystrokes I need to reenable USB legacy plus save BIOS options?

BTW, when I hit CTRL + HOME while switching power on, the USB stick does get powered, but it doesn't seem to boot from it.

I have removed both HDDs so that the stick should be the only boot option left.

 

Using nvflash and a bootable USB drive, you can backup your bios by the command nvflash -s stock.rom as an example.
DOS bios dumping Using nvflash is 100% secure.
