Thanks, didn't work, looks like a new motherboard... -
Hi all,
I'm trying to recover a Lenovo ThinkPad L13 Gen 2 (Type 20VH) with a LAR-2 motherboard (19837‑1) and a MX25L25673G (32MB) SPI chip.
Backstory:- Original BIOS chip was corrupt (4-note beep).
- I don't have a backup bios file
- Tried a dump from a forum (possibly mismatched) — still 4-beep failure.
- I’ve verified flashes and used UEFITool + UEFIExtract on the image.
- The board has BootGuard enabled (confirmed via FIT Table with __KEYM__ and __ACBP__ entries), so I suspect the current image has mismatched key manifests.
I’m looking for a verified working...Leave a comment:
