Hi, I am a Legion Y540 user and I bricked my laptop downgrading from 41ww bios to 26ww, which was definitely Lenovo's fault.
But I bought a ch3341a programmer. After backing up the corrupted bios, I flashed the stock bios successfully, but it turned out many motherboard variables are missing.
Then I found a tool called LVAR by lenovo and wrote most of the dmi variables back refering to my original box and labels on my laptop, including product name, mtm number, sn, etc..
But for other variables, it's really hard to know the original value.
Is it possible to extract UUID and my oem win10 license info from old backup?
Here's my corrupted bios backup. Thank you!
