Description
BIOS dump file packaged as a ZIP archive, about 16.5 MB, originally named X1 YOGA 4TH GEN.zip. The facts do not list a brand, board number, revision or flash chip size, so confirm the exact match yourself before using it. A BIOS dump is used to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. Read the original chip contents and keep a backup first, and make sure the board number and revision of your laptop match the dump before writing anything to the chip.

Questions about this file
How do I flash this BIOS dump?
Write it to the SPI flash chip with a programmer such as the CH341A and a SOIC8 clip. Read and keep the original contents first, and check that the chip size matches the dump.
Will this BIOS work on my board?
Only if the board number and revision match: X1 YOGA 4TH GEN. Dumps from a different board or revision can leave the board dead.
What does “clean ME” mean?
The Intel ME region in the dump has been reset, so it can be used on another board of the same model. Keep your original dump and transfer serial numbers if needed.
