Thanks for the effort in compiling this, however even being pretty experienced in precision instrumentation and electronic repair but I encountered some difficulties.
1: To remove the hot shoe cover plate you actually have to lift on the 'forward' end of the plate nearest the lens to un latch and slide it out, not the "back end"
2: The screws are so tightly glued below the hot shoe that they are nearly impossible to remove, I got 3 out but the same front one that appears to be missing in your pictures is stuck fast. The screw that holds the LVF is also glued fast and I believe it's smaller then a 000 phillips.
3: The back metal plate does appear to be glued to the top of the body and no amount of prying seems to loosen it.
It appears Panasonic intended this camera to be disposable and not dissembled. Sad because all of them seem to get dust on the sensor at some point.
