Gently open the back case by prying along the edge of the cover, starting at a corner of the phone and circling around the phone using a plastic opening tool.
The opening process may take a few minutes. The plastic will make a light snapping noise as the back cover separates from the rest of the phone.
Remove the last tab connecting the motherboard to the front display assembly located in the upper right-hand corner of the motherboard using a spudger.
Once this tab is removed, the flap will be free and will spring away from the motherboard.
Remove the power and volume button switches from the display assembly.
Compare your old display assembly to your replacement part and verify that they match. If there are any small components missing from the replacement display, transfer them over from you old display.
