Hello Ben, and welcome back to the community.
As it appears that the micro-USB power socket is cracked, I think you have two options:
-
Replace the Raspberry Pi board with a new one, paying attention to the fact that your Shake name will change after, as it depends on the Pi board MAC address (Raspberry Shake Station Naming Convention); or
-
Implement a Power over Ethernet (PoE) solution similar to what is described here: Power over Ethernet (PoE) - #10 by Hadders
One of the above should restore your BOOM to working conditions, so you can have it online again.
