Description: Use this guide to remove or replace the screen...

Prepare an iOpener and apply it to the rear glass for at least two minutes to loosen the adhesive underneath.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

Secure a suction handle to the bottom edge of the rear glass, as close to the edge as possible.
If the rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.
Lift the rear glass with the suction handle to create a small gap between the back cover and the frame.
In case you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
Insert an opening pick into the gap you created.
Slide the opening pick to the bottom right corner to slice the adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.

If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener for one to two minutes to reheat it.
Insert a third opening pick at the bottom left corner of your phone.
Slide the opening pick along the left edge of your phone to slice the adhesive.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.

Don't try to remove the rear glass all the way yet. The camera cover and fingerprint assembly is still adhered to its back.

Carefully fold the rear glass to the right side of the phone assembly like you'd open the back cover of a book.
Avoid straining the finger print cable during this procedure.

Use a spudger to disconnect the fingerprint reader by prying the connector straight up from its socket.
Remove the rear glass assembly.

Do not insert the opening pick deeper than 3-4 mm to prevent damaging the motherboard.

Twist the opening pick sideways to pry up the daughterboard cover including the loudspeaker.

Apply a heated iOpener to the screen for at least two minutes or use a heat gun to soften the adhesive underneath.

Once the screen is warm to touch, apply a suction cup to the bottom edge of the phone.
If your screen is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the screen.
Lift the screen with the suction handle to create a small gap between the screen and the midframe.
Insert an opening pick in the gap between the midframe and the screen.
In case you only want to replace the display glass but not the LCD and digitizer you need to be especially carful during the next step. There's a small cable at the bottom right end of the LCD which is very fragile. Only slide with the very tip of your opening pick (about 1-2 mm).
Slide the opening pick to the bottom right corner of the screen to slice its adhesive. Leave the opening pick in place to prevent the adhesive from resealing.

Insert a second opening pick and slide it to the bottom left corner of the screen to cut the adhesive.
Leave the opening picks in place to prevent the adhesive from resealing.

Compare your new replacement part to the original part—you may need to transfer remaining components like the speaker grill from your old screen to your new screen.
Apply new adhesive where it's necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
During reassembly, follow this guide in case you're using a pre-cut adhesive card.
