@taylord Thank you so much for pointing out those pins! You likely saved my sister’s phone. I’m fairly experienced with hardware repair but foolishly allowed one of the coax cables to run underneath the corner of the daughterboard. After cleaning the contacts and reinstalling the daughterboard the speakers and microphone are working, which is why I was trying to replace the board in the first place.
Thank you very much for your clear guide! Even though I had never opened a laptop before, I was able to dig down to my keyboard with your instructions and I'm typing this now with BOTH shift keys :-D
Note: unlike @Bill Aldridge I bought extra screws to replace the rivets and replaced all but four of the rivets using (at my Father's suggestion) flat sharp wire cutters to bite into the stumps of the rivets and then pop them out.
