Hi
I got a NUC7i3BNH, which originally came with BIOS 0036.
My plan is to have VMware ESXi on this box (either 6.0U3 or 6.5).
I saw that there was a BIOS upgrade available, so I updated to BIOS 0042.
But now the system, won't power off, when doing a shutdown of the ESXi software (tested with both ESXi 6.0U3 and 6.5)
I have been in communication with other people with the precise same hardware, and ESXi versions, running BIOS 0036, where the shutdown/power off works.
So I would like to downgrade the BIOS to 0036 again.
But when I try this I just get "Incompatible BIOS Version, Update aborted" using either the F7 option or the IFLASH2 option.
When I try to do a Power Button Menu F4 BIOS Recovery, I just get a blank/black screen, and the system is just on, but nothing happens. Left it there for many hours.
I have also tried the BIOS Security Jumper, but the result is the same as the Power Button Menu F4 BIOS Recovery option.
How do I downgrade the BIOS back to the original 0036?
