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... -

I'm working on a Lenovo LOQ 15APH8, Serial# MP2L9MAV. I want to flash a new BIOS onto it, but I'm also trying to learn this process for my own enrichment and professional development.
I was watching some tutorials, copying the serial info blocks from the old bios to a new bios. Before that though, they use innoextract on the Lenovo .exe. I downloaded Innoextract v1.9 but it tells me my .exe is not a supported inno setup installer(see screenshot). So if I unpack this using 7zip, I do get a .ROM file, but according to my tutorials, I'm looking for a .FD file.
How can... -
