Re: NM-B452_BIOS

managed to do?

Yes

what was the solution?

quite tricky

1. Extracted the BIOS from last updata (lenovo's original).
2. Copied the DMI info from the original backup (seen it mentioned here).
3. Flashed it
4. Shorted jcmos1 on the mobo (until... powered on a few second.. powered off, removed short).
5. Followed the procedure mentioned by the OP... (from step 3 (autopatch --howto).

P.S. I dont know why it didnt worked if skiped step 4 (shorting jcmos1 on the mobo)
