If possible, turn on your device and test your repair before installing new adhesive and resealing.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

The best way to secure the new screen is to apply a sheet of custom-cut double-sided tape to the back of the screen.
