@hp13 Check the capacitors I marked. C222, C223, C230, C227. These are all for the lower microphone. They could have been knocked off or damaged during the charging IC replacement. You should be able to see them from the edge of the board with a flashlight and magnifying glass. The board will have to come out in order to check them though. First reseat and then try a new charge flex before pulling the board. You won't have to install it, just lay it on top to test.
