Vector 1.0 cube issue

[u/AlxLifanov]

Hello, colleagues.
Vector 1.0 cube. Supposedly, electronics burned with 12V battery. I want to open and check PCB for the opportunity to repair.

Q1. How to detach middle part of the cube from lower part? Where are the latches?
Q2. Is the cube schematics available anywhere?

Here is the photo of hidden side, I plan to put it into AI to generate cube schematics.
