YABUGW Yet Another Bios Upgrade Gone Wrong (for NUC8i7HNK). Help (?) :(

Hi, all this is the first (i hope it is not a double post because my browser went funky).

 

So I also did the BIOS upgrade for the NUC8i7HNK.

It went wrong.

I  am stuck at the Black Screen with the Intel NUC logo and the mouse active + two buttons Setup | BBS ib the top right of the screen. Some times there is also a mouse enabled keyboard but there is nothing seemingly happening.

I tried after reading the forums all efforts and the only one that worked was downgrading the BIOS with a USB plugged in the orange USB port.

The problem is that after a put back the jumper in their previous position and boot.

The NUC goes back at the same Black Screen with the Logo and the two Buttons.

When I don't use the jumper the machine boots normally to Windows.

Any ideas?

i just found this from @LeonWaksman 

"

In order to avoid this problem, after downgrade to version 0059, the security jumper should be installed in locked position (2-3), instead of normal (1-2). The method how to downgrading from Power Button Menu (without need to open NUC and reinstall the jumper), was described by @MSuur  in his post dated 20-04-2020, in this thread.

Trying now. Just need to see that if 1-2 (the original) was [. .] . then 2-3 is . [ . .] ?

Hi @JohnB ,

Refer to the page 46-46 in Technical Product Specification for Security Jumper pins.
