Re: BIOS REQUEST HP 430 g3
Still corrupt, but at other places. There's definitely something going wrong when reading the chip. Make sure the chip is soldered properly to the adapter board, the adapter board is inserted properly into the programmer, don't use a virtual machine… also I've heard a lot of problems with CH341A especially with larger chips (128Mb), sometimes using a different software can help but I don't know much about it (I have RT809F and TL866II and no issue with these).
If you flash a corrupt BIOS, the computer won't turn on at all and since you don't have a good backup it'll be harder to restore to working conditions.OpenBoardView — https://github.com/OpenBoardView/OpenBoardViewComment

Re: BIOS REQUEST HP 430 g3
Guys,
so I just soldered the chip to the larger adapter board.
while reading the chip I saw a thin wisp of smoke coming from the chip.
I unplugged the programmer and checked closely under the scope.
Can anyone tell me if the two pins circled and meant to be connected.?
There is a solder link between them.It doesnt look like a track.Attached Filesif you find these attachements useful please consider making a small donation to the site

Re: BIOS REQUEST HP 430 g3
oK,
I tried ch431a ver 1.18 as has been suggested to use with this chip.
The software detects the chicp as 25q128bv instead of 128f,,however it reads and VERIFIES..!!
Pls check this one guys..Really appreciate the help.thnxComment

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.- I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
- I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
- I could only locate two chips that look like bios chips. Could someone verify this

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows
