Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS
Hello everyone,
I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.
This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.
I have opened the laptop and identified the main BIOS chip... -
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...
