In step 9, you should mention the small circuit board that has to be released from the screen on the top right of the screen.  (It can been seen in the step 6 picture.)   It would also been helpful if you mentioned the flange on the ribbon cable connector that should be loosened to allow the cable to be disconnected.   The guide allowed me to disassemble and reassemble the unit with a new screen, but the camera was totally inoperative afterwards (would not turn on or charge at all) so I can’t say the guide was helpful.
