Hello frends,

So I have read an save BIOS from the chip with a ch341A programer.
On the Lenovo driver site I have downlaoded the BIOS-Update but I cant extract the BIOS-Firmare to program the chip!
Can someone help me!
I have a
Legion C730-19ICO Desktop (Lenovo) - Type 90JH
Serielno. : S1011C9G

That is the Link to the lenovo BIOS:

Thanks a lot

post your original backup

Hello, I have uploaded my original backup

I have tested the BIOS-Frimware with no DMI, but same problem.
Maybe I'm on the wrong way! Maybe I have to check the mainboard more...
If some can give me the Bios with DMI, I will check it again.
