Hi, i have encountered a similar issue on my D810 as some Users before me. 

./mtplvcap -debug server
[0000]  INFO usb: found: 04b0:0436
[0000]  INFO main: started
[0000] DEBUG lv: manufacturer = NIKON, product = NIKON DSC D810, serialnumber = 0000002009398

The shutter stays closed and the mirror up mode doesn't do anything either.

@Squitor Thanks for reporting an issue. Which version of mtplvcap did you use?

Squitor commented 2 years ago

I used version 1.4.1 and also tried both fixes. All came with a similar result.
