Hello,
Windows Update installed the 01.28.00 Bios on my 830 G5.
Now the boot screen shows "Warning This BIOS is not for production use"

The version number is strange:
wmic bios get biosversion
BIOSVersion
{"HPQOEM - 0", "HP - 10000"}

Everything I tried to update or downgrade my BIOS under windows or within the Boot menu with an usb stick failed. invalid firmware in BIOS
