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.

      Hello there!
      I am new on the forum. I'd need some help. I own a lenovo ideacentre t540-icb g, and i would need to unlock all the options in my bios, especially overclocking and thermal configuration. I tried with both amibcp and mmtool, but i didn't succeed (Error 18).
      I wonder if you could help me or give me some advice.
      Thanks in advance.

      Hello everyone! I am looking for an answer to a problem I cannot find a solution to ... I purchased an Amd wx 4150 MXM GPU module su e bay to upgrade my HP 8570W Mobile Workstation which is currently equipped with a Fire Pro M4000. Once the new GPU has been installed, the PC screen no longer turns on but works only with external monitors connected via the docking station. The same happens once the drivers are updated! If I put the old card back on, the integrated monitor starts working again ... How can I fix it?

      Bios Release Version – v2.0.0
       

       
      Updated or Modded Items:
      A11 UNLOCKED BIOS FOR m18Xr2 (UNLOCKED BY SVL7 AND FULL CREDIT GOES TO HIM FOR UNLOCKING!)
      SVL7 Also created the PRR2.EXE tool that allows you to flash the new bios by unlocking it.  (FULL CREDIT GOES TO HIM FOR THAT FILE PRR2.EXE)
       
      Here are ALL the things I've added, modded, and enhanced on this bios -
      I've added FULL LEGACY SUPPORT ON THIS BIOS with ONE or TWO CARDS (SLI).  You can FINALLY use Win 7 OS on your machine and run the 900 series GPU's! 
      This is a MAJOR breakthrough!
       
      LEGACY SUPPORT Confirmed.  Works with 900 series GPu's in single OR SLI formation Updated the Intel RST Legacy to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated Intel RST UEFI to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated the ONBOARD Video Card for the HD3xxx to v2171 - FROM v2132 Updated ONBOARD Video Card for the HD4xxx to v2171 - FROM v2132 Updated the LAN Firmware & PXE Boot from 2.0.5.9 to v2.0.6.6 ADDED NvMe Support for m18xr2 ADDED M.2 support for m18xr2 Updated CPU Microcode to v29 for the 2900 CPU's Updated CPU Microcode to v1c for the 3900 CPU's Updated GOP Driver for Intel Sandy Bridge CPU Updated GOP Driver for Intel Ivy Bridge CPU Updated MAIN GOP Policy module for the m18xR2 Eliminated some code that wasn't used in the m18xR2 Updated CSM Module (v2) Streamline some coding to make mod(s) run a little more efficiently (v2) Added FPARTS.TXT to rar file in v2. (I had forgot to add it in v1) v2.5 to be released shortly.  I've updated a few more modules that I didn't realize could be updated.  (It's only 3 modules, but it's still an update!)   It should be released in about a week.  Hope this helps ya'll!  
      Instructions to flash:
      Use a flash drive to create a boot disk into dos Unzip ALL files into the root of the flash drive (flash.bat, r2final.bin, fpt.exe, flash.bat, prr2.exe, fparts.txt,m18r2.hdr, m18r2.hdr.bin, readmefirst.txt) BOOT INTO DOS – Note, that when you set the bios to legacy in order to boot into dos, you MAY have to reinstall OS!  (Just be prepared to reinstall no matter what) Once you boot into dos, run the file flash.bat It will unlock your bios (THANKS TO SVL7’s BIOS UNLOCKING TOOL – ALL CREDIT TO HIM FOR THIS TOOL!) Let it flash… Reboot your pc, and enjoy the MASSIVE updates!  
      Be on the lookout as I do plan to release newer version with more updates in the future.  However, it wont be for at least a few weeks as I'm now working on legacy support for the m17xR4 and several other systems.  So please be patient!
       
      ENJOY!
