BIOS F16 to 15.A (spectre X360 2020) Unable to open BIOS Signature file (USB)

HP Recommended

Microsoft Windows 10 (64-bit)

Hi,

That is nice to have updated to F16 but how do I get back from there? The F16.A update is no loger available on HP's official support page for my PC.

The problem is the software will not let me update back on an older version and making a USB with that BIOS doesn't help:

F9 on startup and select USB/HP/BIOSUpdate/BiosMgmt.efi

and "Unable to open BIOS Signature file"

 

[up] I don't need to update back anymore now that I know that my bios isn't the cause of thunderbolt not working properly, but drivers were..
