回答“I've damaged 2 of the 4 WiFi BlueTooth cable tip socket connectors.”Turns out the mangled gold-tipped clamshells in those antenna connector tips may NOT have been irreparably destroyed. Today I went back in and looked at the connectors that didn't quite mate with the pins on the BT/WiFi board, and with magnifying spectacles it appeared I might be able to spread those two leaves apart. I did so with the smallest jewelers screwdriver I could find, and after doing so I managed to get both damaged connectors to seat onto their mating pins on the Comm board. AND, BT is BACK (even to the level of streaming to my AirPods Pro earbuds!
