Thanks for this tear down! At what step can the battery be removed? It *appears* to be mid-step-5
There are four Torx 10 screws on each side of the display. There are other Torx 9 screws in this area - they do not need to be removed, as they hold other pieces, like the camera, to the frame.
When lifting the display screen, lift it only 30°, or else you'll accidentally pull out either the sync cable, the power cable or more likely, the data cable. You'll want to know where they came from!
