Lenovo Carbon X1 NM-b481 Brick

[chick0n]

Hi

I have a bricked x1 6th Generation here.

It powers up, but has black screen. After removing the BIOS Batterie for a few minutes and Restart, it beeps error code "0285 TCG-compliant functionality-related error (might be the TPM initialization failure)".

What would be the next logical step to try? Flash the BIOS Chip manually with programmer?

How can it be done?

Thanks!!
