Wipe away all the flux with a Q-tip and some IPA (Isopropyl Alcohol). Never spray "IPA" straight onto the mic, or anywhere near the screen, it might cause distortion later on in the mic and color distortions between the LCD layers.
Tape and or glue the torn parts of the flex cable so that it doesn't tear further. , rather use epoxy or such. I personally added a drop of epoxy and then taped around it to create a neat package around the torn flex.
I also had to cut a small hole in the mic enclosure for my jumper wire to fit through atop the flex nicely.
