Using the spudger, start to gently pry the motherboard from the back of the phone and work your way around the perimeter of the motherboard.
There are copper ribbon cables connected to each side of the motherboard leading to the buttons for volume control and the camera that need slid out of the phone casing as the motherboard is being removed.
There are three in total, but do not remove the top one from the phone casing yet.
Using tweezers, carefully disconnect the display ribbon cable from the screen assembly and phone by lifting up on both connections.
The display ribbon cable will still be attached to the phone via the hinge. The disconnection of the display ribbon cable in this step is to remove the screen from the screen assembly.
