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)... -
I'm trying to extract a flashable bios file(ch341a) from the lenovo bios executable download. I have tried the instructions from this site https://starkeblog.com/lenovo/uefi/2...pdate-exe.html, which are not working. According to those instructions, after issuing the commandit should create an \app folder, inside which, I should find a newly created "7wcn38ww.exe" file. I should then be able to extract that using 7zip and find my .FD file.Code:
"innoextract 7wcn38ww.exe"
The trouble I'm having is that I'm not getting the newly... -
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 Everyone,
I have Thinkpad T560 Which has corrupted BIOS. I have acquired Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, i need a bin file for the BIOS. I was able to extract the .exe file of BIOS from Lenovo given here in this link:
https://pcsupport.lenovo.com/au/en/p...me=BIOS%2FUEFI
In the extracted files, I see that BIOS containing file has extension .FL1 and I need to extract or convert it... -
Hi, can someone help me please with the removal of the bios password of this dump.
Someone desoldered the bios chip, tried several "methods" but with no luck, and he gave me the dump to try to search some help.
For now he deleted more things and bios password is gone but laptop doesn't show serial, model etc.
Also, I updated bios to latest version, when he will write the dump again without password, it should be better to put back the old version that was orignally or doesn't matter? Because from what I've read this laptop has 3 bios chips, don't know if has...
