How to remove this epoxy like glue?

Hi,

Anybody has ideas on how to remove this black, epoxy like(?) glue? (see pictures)

I tried heating it with hot air tool, but didn’t make any difference. It surrounds the cables, and worse, keeps the PCB in the case.

The material is called potting. Its used to protect the wires and/or connections.

What are you trying to do?

Take out the pcb, find the TDO line, as it is not routed to the SWD connector, but to a via, and from there maybe the other side.
