820 3023-A Not booting not mounting

Extreme

Hello, I received a job with a very damaged board 820 3023-A and I decided to replace it as they were too many issues.
After I have replaced the board I am unable to boot from the same hard drive that was in.
The hard drive is working all right but it seems that I can manage to mount it or to do anything.

This has the FileVault on but the customer knows only the login password.
If I would at least manage to get to the login screen it would be amazing

Any help would be greatly appreciated

The new board doesn't have APFS support.
Get an empty SSD and do a fresh install of High Sierra on it; NOT the client SSD!
Once finished, put back client SSD.
