Thanks for your answer dear peste. Unfortunately, I can't access the BIOS because it's password-coded. No idea how to secure it. Best regardsComment

Okay, I understood. The version is: P78 Ver.01.40 11/19/2021 - Best regards

Hello to all the experts. Can anyone help me? So far I have only found out that the "BIOS chip" has to be soldered out and programmed externally. Is there really no other solution? Thanks for every message and best regardsComment

Yes, if you don't use the CH341A (which works poorly with clamps)

Hi Guys,
Would you please help me to clear the BIOS for HP EliteBook 840 G4
During the Windows setup process, it prompts you to enter the company credentials.
Thank you in advance.Attached FilesComment

We can`t help you unless you post your bios backups, and type and post the laptop serial number. Read https://www.badcaps.net/forum/troubl...before-posting

Thank you SMDFlea for the reply,
How many Bios backups do I need to post to fix that issue?
Main or second BIOS too?
Thanks.Comment

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,... -
Hi,
I'm looking for the original BIOS file for the Medion Akoya S6445 – model MD61280, preferably in .bin or .rom format for flashing via CH341A programmer.
The BIOS chip is a GStek GS7166 (25Q64 compatible, 8MB SPI).
Does anyone have the correct BIOS file or know where to get it?
Any help would be greatly appreciated!
Thanks!

Hello Everyone,
I have Lenovo Legion 5-15IMH05H (Lenovo) - Type 81Y6
and I have encountered a Black screen on startup. I have tried the power drain and all sorts of tricks that were available online to revive it but no joy.
Since I have already an expired warranty, I am thinking of flashing the BIOS externally. I have a Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, I need a bin file for the BIOS. The latest BIOS executable can be found here but I need the bin file to flash it externally.

Hello,
I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.
However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)...
