Great repair guide but the logic board screws are Torx T5 (not T4) at Step 25 of guide
Thanks! I would never have guessed everything that needed to be done without this guide. Man, I HATE the tiny, tiny screws. Lost one even after sticking all the screws to tape, just in case. :( Took the full hour to put in in, but the new battery is charging like new.
Be SUPER SUPER CAREFUL pulling off the gold WiFi antenna connectors! As described, use the spludger to press up the black cable just behind the metal connector. I tried to ping them off from the bottom of the gold connector where it clips into the socket on the motherboard and ended up pulling off the SMD sockets from the motherboard - huge and costly mistake that will probably render it useless.
