Anyone got a picture of the GPIO connector? I took mine off to attempt to change the heatsink (didn't push my luck so left it) but I didn't take note of how the black connector was orientated and what pins it was plugged into
EDIT: Took a gamble and thankfully it paid off. All running again no problems
FYI you would have completely fried both boards if you plugged that in the wrong way...your a lucky dude
