Upgrade BIOS to HP BIOS A0.11 with created flash key, fails validation! No .SIG file.

HP Pavilion Desktop - 500-500z
Microsoft Windows 8.1 (64-bit)

The Desktop locks up on first shutdown and restart after reinstallation of Microsoft Windows 8.1 Set-Up . Not able to use the PC normally because of freezes, non responding OS. So I executed F2 run an Extensive Hardware Test... PASSED?!

 

Possible BIOS error or corruption?  Current BIOS A0.07 and Current OS Windows 8.1 Pro.

I tried Upgrade to BIOS ver A0.11 (Jan. 16, 2017 recommended by HP) followed instructions to create Flash drive "HP_TOOLS." Reboot and hold ESC, enter F2 and execute BIOS Update and message is " Validation Fail ." No signature file for the .bin file?!

 

I can't even use the reinstallation DVDS to Factory State because the first time it reboots to complete an OS install,  it Locks up after reboot and the install FAILS!

 

I can reinstall OS from Microsoft Windows 8.1 Set-Up and install Updates and it does the same, locks up and interrupts the updates and fails. Rebooting into Windows Locks up and then nothing to do but reset.  😞

 

Any advice on a fix for this PC problem would be very helpful because currently I can't use the Desktop at all.

Thank you very much!

Upgrade BIOS to HP BIOS A0.11 with created flash key, fails validation! No .SIG file.

I forgot to mention that the built 2015 HP PC Pavillion Desktop 500 is OEM Windows 8.1 Pro, so why would I bother with original Factory Restore DVD's for complete drivers and supported programs? If HP Support doesn't support 8.1 Pro should I Upgrade to Windows 10? Microsoft is still supporting Updates and software for this system. Thanks for your advice, but the issue is the BIOS update problem which is not being addressed. If HP recommends firmware upgrades for functionality of current PC's and recommends it to fix issues, why does HP offer firmware upgrades to up to date systems? That is signature files to accompany bin files to validate critical hardware upgrades? A0.11 Rev. A is without a .sig file to validate the bin file? This Desktop had symptoms of errors booting into windows and shutting down progressively worse each time. To the present time, not even usable.

Thank you for your response.

Hi @Orichaoco,

 

Thank you for replying,

As I understand you have installed Windows 8.1 pro and having issues with the Bios, As mentioned on the previous post, installation of Windows 8.1 pro is not supported. I would suggest here is to get back to the original Operating system which was shipped with the PC. 

If you haven't created one, I would recommend you contact our HP phone support to order a set of recovery media for your PC.

 

Please use the link from the previous post to contact our HP phone support.

 

I hope this helps. Let me know if you need any further assistance. I'll be more than happy to help.
