Update BIOS for NUC8i7BEH : nothing happens. Could you help me ?

[RFauc2]

I've tried all the three ways (msi, F7, F2).

Each time, freeze.

First, MSI : nothing happens

Second : I strike enter : nothing happens...

Third : I click Yes : you know what ?... nothing happens.

I need to update BIOS because the audio doesn't work

(like https://forums.intel.com/s/question/0D50P000049Y7gVSAS/nuc8i7beh-cant-install-drivers?language=en_US)

Other problem I'd like BIOS could solve : When I shutdown... then blue light stays powered... I need to press it 5 seconds to set the power off.

Thanks if somebody could help me.

if it could help somebody, I reseted the BIOS with the jumper.

After doing it, the update worked !

Merry xmas to everyone.

1. You did OK recovering your bios with Security Jumper removed.
2. About your other problem - "When I shutdown... then blue light stays powered... I need to press it 5 seconds to set the power off." This is normal operation for your NUC. If you depress the Power Button (while the NUC is ON), for less 4 seconds, the NUC enters Soft-Off/Standby state. If you hold the Power Button depressed for mor than 6 seconds, NUC will go to Fail safe power Off state.
3. If you want your NUC to go to OFF state after short depressing on Power Button, you should define this Windows Power Settings. System>Power & sleep > Additional power settings (on right side)>Choose what the power buttons do - set When I press the power button to Shut down
