I suspect that what you read about the Mill-Max socket might have been for a very specific case. It is not a general technique AFAIK.
You will have to find where on the PCB that it is damaged, and solder a bridging wire over it. One end of the wire could be anywhere on the row that currently does not work.
There have been several revisions of the DZ60 that might be different, so it could be difficult for anyone to give more specific advice.
