Product: ProBook 430 G4
Operating System: Microsoft Windows 10 (64-bit)
Hello, I have problem with updating BIOS on my notebook HP ProBook 430 G4. When I try to update BIOS, it shows error message:
"bios signature verification failed,
please download the file again the update system bios"
I tried almost everything, but nothing works. (older BIOS version, download BIOS directly from HP support sites, BIOS recovery with known keybord combination Winkey + B + PowerON)
Thank you very much for any help.
