Press Shutter Release Again

I have getting error "Press Shutter Release Again" on my Nion D3300. Many videos on internet have suggested to free to stuck read gear at the bottom of the camera. I am struggling to open the back plate of the D3300 and can't find any video/instruction online of disassembling D3300. Any guidance would be helpful.

Regards,

A

I'm having the same problem, can't find any info about how to bust this thing open. Did you figure something out?
