@DeathBringer

You are a God!!! Thank you very much for your help with my big problem. Windows is booting now.
I dont know if Windows10 is a good option, or would it better to take windows 7?

I will try an ssd now.

Greets and Thank you very much,

Hello guys, I have the same problem as the others had...
asus k75vm, tried to update from 208 to 234 from ezflash and got "verify error!! ROM Update not Success"

I dumped the bios content with flashrom using a raspberry pi + 8pin soic (already used to flash a lenovo, worked well) and tried to flash a stock bios downloaded from asus website, with pad added at the end of the rom to reach the 8mb size... but isn't working :/

Can someone help me recover the bios? Here is the dump...
Thanks a lot!

Good day. I also have a problem with Asus K75VM laptop. Bios flash from 216 to 221 went bad (WinFlash). I have made a dump of the chip contents, please find attached. I tried UEFITool to have a look and it shows errors:

I do not exactly know how to proceed. I think something crucial is missing in the BIOS but I don't know how to put it back in and reflash.
Could someone help me with this, thanks in advance!

@niwde You might try the attached file, it's on 216. Don't know what happened to your bios, bios region moved by 2kb "padding", dxe volume on 216, pei volume on 216 despite last module and 2 bytes.

Please do a dump of your corrupted bios again and compare it to the first backup you made. If you write to your flash everything that might have been receoverable is gone, so you should be sure to have a good backup!
Machine specific information is in 440000 (your bad bios dump at 440800), first NVRAM was unreadable, second NVRAM seems OK.

Replaced NVRAM1 with empty from 216 stock bios, replaced PEI (last) volume with stock 216, and moved everything back to it's normal place.

@lfb6: Many thanks for analyzing and reconstructing the BIOS. I have written it back to the chip and the laptop is working again! I am curious which tools you used for fixing the BIOS.

Nice to hear that it worked, thanks for the feedback. I used UEFItoolNE for structure and HxD. for replacing volumes I'd normally use UEFItool025, but since the last volume in your bricked bios wasn't recognized as a volume I had to do it manually.

@ lfb6

Thank you so much lfb6 !!!!

My laptop is back to life.

I had no original dump from my old bios because it gave readout errors and probably due to a bad chip, also readout and verify did not match.
