Love the guide! If your mic still doesn’t work look into the headphone/mic jack and see if the two pins are pulled down inside. If they are stuck up then the mic will default to the jack mic input even if there’s nothing in the socket. I pulled mine down with the Ifixit tweezers and this fixed my mic problems.
