JUST finished replacing the motherboard in my D3200, thanks to this tutorial!!! I agree there were a couple points that need to be addressed, like the lack of mention of the screw under the thumb-pad on the back, as well as the screw under the dial on the upper right of the eyepiece. I chose to do the soldering, which wasnt too terribly bad. After reassembly, SELF HIGH FIVE!!! Now I can give my father-in-law his camera back WITHOUT a busted usb port!!! :) And he is none the wiser to my breaking it in the first place. Lol. Plus I now have my D5600 my wonderful wife just bought me, to enjoy!!!
