Hello, greetings to all
I have tried in every way to downgrade my hp 255 g7 laptop, since I have problems with the usb ports (continuous disconnection in most of them, power supply) since I updated the bios version F.34 to F.40.
I have modified the platform.ini file but I can’t get anything.
I haven’t been able to do anything, I have read different topics and the truth is that I have downloaded different programs and I can’t downgrade. I would appreciate if someone could help me with this.
