    • 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.

Заключение

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

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

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.

Take your e-waste to an R2 or e-Stewards certified recycler.

Very good guide. Thank you very much.

I found I needed to use a nail file to help get the back off at the start, done very carefully.

To heat the phone to make the glue soft, I sat it on a hot water bottle for a few minutes, that worked beautifully.
