Forcing Bios downgrade from HP(AMI) F12 to HP F11 on Omen 40L Desktop (F12 Bios seems incompatible)

[Zuru1967]

Having researched further into my computer reboot problem, it now seems that the updated bios which was installed by Windows update has left me with a poorly working computer. The AMI F11 bios which was included in the original computer was updated to F12 recently during a windows update which I accepted as it was an option.

The F12 update is potentially not compatible with the system and as such I am seeking to revert to the original F11 bios. I have tried using multiple ways to do this including a straight forward download of the HP SP package which left me with no update. Using the UEFI bios flashing system, this left me with the constant message of the bios sig file not being accessible on either SSD (File was in the correct place) or the USB stick. 

Thus I am left with a system which will not accept a flash of the bios back to F11 (An older bios cannot be flashed onto the system as the HP software will not allow it)

I can not revert to the previous working bios as this doesn't change back to F11.

I have spoken with two chaps from HP technical support with no solution thus far and no phone calls back as promised. What to do? 

Thanks

Hi @Zuru1967

Welcome to the HP Support Community.

I understand that you are experiencing difficulties in reverting Bios F11. I'd like to help!

Please follow the steps mentioned below.

Note: You may want to backup the data before you proceed with these steps as mentioned. Keep the bit locker key saved.

Prepare your computer for the BIOS update.

• To prevent possible problems, close any open applications, and temporarily disable antivirus software and BitLocker before updating the BIOS.
• Close any open applications.
• Temporarily disable your antivirus software. In Windows, search for and open Security and Maintenance settings, and then click Security to access virus protection settings.
• Temporarily disable BitLocker drive encryption. In Windows, search for and open Manage Bitlocker. Click Suspend protection, and then click Yes. Be prepared and have the BitLocker recovery key available.
• CAUTION:
• If BitLocker is not disabled, the next time you restart the computer the BitLocker key might not be recognized. If you do not know the BitLocker recovery key, you might lose data or need to reinstall Windows.

Also go throught the link and follow the steps which says -(Update the BIOS manually from a USB flash drive (outside of Windows) Click here
