I have made a dump with my CH341:

So maybe the pw is contained in the EC and not the bios.

Okay, on an other device I did it myself. Was quiet easy with your help.
I just replaced the DMI-Part in the update file from the Lenovo homepage with the one from dump:
The DMI is locatet on 0x6C1000 (Where it says DMI 😇...)
I did not recovered the Windows Key, that is propably at 0x425000

The toools I used: HxD and TinyHexer. For Flashing a cheap version of theCH341B and the AsProgrammer_2.0.3a

Hope this can help someone.

Thanks again for the support here!
