Hi everyone.
I have an engineering sample of a Lenovo ThinkPad X1 Carbon 11th Gen (TYPE 21HM-2FVT05, S/N PF-40G7CD) with an Intel Core i7 1360P (ES – Intel 0000). Since this is an engineering sample, the BIOS had a massive number of various settings. One day, I was experimenting with the BIOS settings and, after saving them, the laptop stopped booting and played a melody after pressing the power button, signaling error code 0002 (Internal bus error), just like in this post: https://www.badcaps.net/forum/troubl...shooting-lapto... -

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 need help getting a modified BIOS for my system. Since I have an engineering processor, is it possible to add the microcode of this engineering processor to the latest BIOS for this laptop model? I think since the BIOS is old, that's why the Wi-Fi driver is not installed on Win10 and Win11, the sound is not adjusted (error code 10 in the device manager) and the screen brightness. The laptop also has BIOS chips W25Q512NW and W25Q128JV, how can... -
