How do I bypass AFUWINs file size checker for flashing BIOS roms?

Recommended Posts

A part of my BIOS got corrupted that controls my laptops backlights. Other methods like the Gary Key fix did not work for me because I do not get any light up during post. i followed this guide  that says I need to extract and use the 6MB portion of an 8MB bios dump, only AFUWIN tells me "Error, ROM file size does not match existing BIOS size which is because my laptop BIOS size is only 5.87MB.  I don't need to flash the whole BIOS, I only need to flash a portion of it. 

 

I've searched everywhere online for a dump of my laptop model but non exist that I know of.

Try this procedure:

 

Download and extract AFUWIN v3.05.04 (in attachment).

Download and extract archive GL502VT.rar (in attachment).

Step 1. Run AFUWIN (AFUWINGUI) and go to "Open" and locate the bios file GL502VT.bin

Step 2. On the Setup tab of AFUWIN, check only these boxes: "Do Not Check ROM ID" and "Non Critical Block 2". Uncheck all others boxes. Then click on "Flash".

Step 3. Once the process has completed successfully, simply close AFUWIN and restart your system.
Done, now your KB backlights should work again.

thanks for taking the time out of your day to respond. Unfortunately (again), this didn't work.  Is this a bios pulled from the manufacture website? or a dump you got somewhere? From my understanding, the bios files on the website do not have the required sectors to flash and it needs to be a dump from the same model. If its the former then I guess i need to keep looking. if its the latter then I guess im screwed.

Ok. Try to use this bios dump:  https://files.fm/u/gkqunrbr

talk bout timing. At the exact same time (8 mins ago) I managed to find someone on Reddit with my model and they managed to give me a dump of their bios. Although, theirs was also 6MB. Im wondering why theirs worked and not anything else i've tried.

I didn't quite get it, have you already managed to fix your keyboard backlit issue?

Yes, I managed to find someone online with the same model who could dump their bios for me.

      i want to ask two favours and a question from this community ..
       
      1.) Can someone mod my 940 mx to increase the target temperature and allow higher overclocking than 135hzband voltage control
       
      2.) Allowing my i5 7200U to be undervolted to reduce overall heat 
       
      The question : I repasted my gpu and cpu cleaned it thoroughly, made sure twice everything is connected properly, use a cooling pad and yet the upper portion of my chasis above f1-f12 keys is so hot that i can roast peanuts on it. 
       
      (if i left out any info or missed something please reply i would really love to have a page that has everything for people who have this laptop specifically for light gaming.)
