HP Recommended
Product: HP ProDesk 405 G8 Desktop Mini PC
Operating System: Microsoft Windows 11

Hi,

I have problem with updating bios on HP 405 G8 DM (SKU 64L88EA).

 

Internal version of bios is 1.05.03 (T25, date 08/19/2022).

Latest on web is 2.06.00 and there is no 1.xx.xx version in history. And updating shows "BIOS signature verification failed". Tried from Windows 11 or from BIOS/USB - the same.

Any ideas how to update to 2.xx.xx line?
