Thanks! Put my DMI on virgin bin and works. Disable Manufacturing Mode and fix some DMI parameters with HP BCU.

Not having a programmer, I tried solution number 1. I followed post 2, but obviously I'm doing something wrong, because when I start the USB with the win+B combination, the black screen always remains

Hi guys..
I followed this guide: https://www.badcaps.net/forum/troubl...-file?t=121948

I did everything up to the end of post #3, but then which file should I flash on the motherboard and above all how?
Sorry but not an expert. I just want to fix it for a friend. Thank you with all my heart.
