Use the "copy BIOS to any file location"  option.

 

Choose C:\downloads as the place to save it or another location, such as the desktop.

 

Exit Windows and power down the desktop.

 

Press the start button and begin tapping the F2 key to invoke the PC Hardware Diagnostics UEFI environment.

 

Choose Firmware Management at the first menu.

 

Update the BIOS and point the utility to the location where you saved the BIOS ROM file and committ to the update.

 

Do not turn off the PC until the update is complete.

I'm a bit anxious to proceed, because the new version nr will be 00.00

I also do not have a signature file as mentioned on these dialogs

So you have pathed to the save location and looked for it?

 

You may have to decrypt the BIOS files as described in the following tutorial.

Yes, I browsed to the location I saved the bios file (on a USB stick in my case)

 

If I select that file, eg: 'BEE_A011.bin' the above screen is displayed and the new version number is labeled as being version 00.00, I am a bit afraid to continue, last thing i like to do is to brick my motherboard

I created a recovery USB stick as described in that tutorial, allthough opening the bios file with that andy tool did not give an RSA.SIG file and a .DEC file

The recovery filename andy tool returns is exactly the same as the bios file name.

 

So with this recovery USB stick i tried recovering the bios (just to test if it worked) 

Recovery went smooth so in case of a disaster the USB stick would save me, right?

 

Now i tried updating to the new A0.11 Rev.A Bios again,  i started my system, pressed F2 

Firware management, Update bios, Browse to 'BEE_A011.bin' and choose 'Apply update now'

 

Within a second i got this screen:

 

WP_20160302_14_54_53_Pro.jpg

 

 

Why is this happening, why won't it update....File name: sp74558.exe Version A0.11 Rev.A is listed on the support page of my pr0duct??????

And why is File name: sp70923.exe Version 80.20 Rev.A not listed as previous version for a HP Pavilion Desktop - 500-405nd?  The only other file i see is Version 80.12 Rev.A (under window 8.1)

HP's Engineers name the softpaqs and versions of files and that is certainly not something that a volunteer would know or have control of.  

 

Just consider it one of those mysterious things in life that you can't  change.
