The camera socket seems to have 1 pin completely burned out, clean again. And I still see some residual damage on other connectors. Also I recommend flipping the board over, peel off the top shielding sticker to see the water damage below. Touch panel, home button and LCD backlight have relatively high voltage inside the phone, for this reason the chips and connectors are very likely to have water damage around them.
