Have you considered trying a Samsung Service Centre or a standalone shop that helps with hooking up phone's to see if they can help @TomaszMaranaTha

As for moving the motherboard this may not be straightforward due to security protocols that also exist.
Also due to the current Samsung Community Forum Rules we are unable to advise further.

The advice I offer is my own and does not represent Samsung’s position.
