How to fix corrupted BIOS using CH341A programmer

[@developakr]

This is a very easy and fast method to use the CLIP for BIOS flashing. However, always desoldering the BIOS chip if possible. This will prevent programming errors and motherboard damage.

thanks for the video! the bios edit works on my asrock FM2A55M-DGS R2.0 1.50 ROM

[@developakr]

Great to hear that it helped you!

It helped to fix my Intel DG41WV motherboard. My system is 14 years old 😊

I have a Prime B460M-k it was bricked so I tried corrupting a bios update however I messed it up even more as it turns on for 30 and restarts, ram lights and gpu flash but crash free no longer kicks in

very interesting! Great video!

Thanks!!!😉

Curious about the line 800 removal part as well when going from cab to bin.. what exactly is occurring in that step? For other motherboards/bios chips, is the line 800 a standard or does that line number change by manufacturer etc?

[@eth1111]

I'm confused too, because for my model it already downloaded as a bin file

[@KartikayBagla]

Great video, how do you figure out if your bios is corrupted though? (And not the cpu/gpu/ram is dead)

[@developakr]

sometimes the BIOS failure can be determined as follows: kzbin.info8ErJIUH9Tzs?si=QHM0k_YdfVko1vaI

So cool!

How do you know that 800 lines need removal? Does all of the information in the .cap file before the beginning of the bios section need to be removed? In my ASUS P8H77V bios .cap file, when viewing with UEFI Tool, there is an Intel section with ME after the AMI aptiva capsule header. I've tried to create .bin files from ASUS .cap many times now, with no removal of lines, then as you showed. Either way, I get verification errors: like this one when flashing the IC with the file that removed the first 800 lines: Verification error on address: 0x000005E0, Device: 0xFF, Buffer: 0x1C. When I read the IC and create a file, compare it to the .bin file that was written (using HxD as well asn NeoProgrammer), the files are identical. Either way though, when inserting the IC in the board and booting (after battery removal and CMOS clear), no boot.

thats the power of reverse engineering + experience

[@butanding1987]

Is it also 800 offset if the BIOS chip and file is 32MB? Thanks.

thank you👍👍👍👍

Thank you for your interest my work😉

Hello sir, can this method be used on the BIOS chip of a Lenovo laptop? I just flashed the BIOS yesterday and my laptop doesn't display anything except a black screen, with the caps lock and esc lights always on after pressing the power button and the fan spinning. I have tried many methods online but without success.

1. Even putting the clip on the BIOS isn't 100% and needs some practice 2. Lenovo EPROM contains more than the BIOS so making sure your get a correct image to reflash with is essential. Probably need to talk to expert user community to sort this out.

nice

[@franciscomaciel4963]

Any idea where I can get a tutorial for CH341A programmer/software? If it is in Spanish... Better!

[@user-hq3vz5tk1f]

did you click the read button and erase? or just click detect and erase

[@developakr]

Detect, Erase, Verify, Program

Hi, work this for all bios files. I have an acer notebook with the same problem, full speed fan, black screen.
