With the spudger still inserted between the rear case and front case, slide the spudger along the right edge of the device, moving toward the bottom, prying as you go.
Continue prying along the bottom edge of the device from right to left, freeing it from the front panel.
Continue sliding the phone in the same direction, past its "closed" position, until four more screws are revealed. You will need to lift the slider slightly to get it passed the "closed" position.
Insert a spudger between the back and front case of the display assembly, and peel the two ribbon cables off the two adhesive pads along the back case of the display assembly.
The location of the pads on the back case is shown. The top left corner of the case is the corner of the phone shown in the first picture.
