It seems you have snapped off the female connector door (As I have following your guide; this is the black piece with pins attached to the bottom of the gold strip) from the logic board... I was told that the device is broken in this state, since the strip was to be released from the connector, but am wondering if the door can just be soldered back onto the logic board and still be functioning?
