Take note of the two seams on the edge of the phone:
-
Screen seam: This seam separates the screen from the rest of the phone. This is where you should pry.
-
Frame seam: This is where the plastic frame meets the back cover. It is held in place by screws. Do not pry at this seam.
-
Before you begin, note the following areas on the screen:
-
Screen flex cable: Do not insert the opening pick deeper than instructed or you risk damaging this cable.
-
Adhesive perimeter: Prying beyond this narrow perimeter without angling the pick will damage the OLED panel.

-
Apply a heated iOpener to the right edge of the display for one minute to soften the adhesive.
-

-
Place a suction cup as close to the right edge of the screen as possible.
-
Lift the suction cup with a strong steady force.
-
Insert the tip of an opening pick into the screen seam no more than 1 mm.
-
-
-
With the pick 1 mm into the gap, pivot the pick upwards to a steep angle.
-
At a steep angle, carefully push the pick into the gap about 1/4 inch (6 mm). The pick should slide in below the OLED panel.

(T3 worked for me)
The back cover I bought didn't include the sensors (fingerprint and camera flash) and a grommet thing over one of the speaker holes, that are attached to the back cover. So I had to transfer those pieces myself. I needed to use heat from the iOpener to soften glue that was holding them on to the old back. The replacement back seemed to have replacement glue in place under peel tape. I didn't replace the glue holding the screen, instead heated everything up with the iOpener when replacing the screen in the hope that the old glue will still work, fingers crossed.
I suggest following this other guide instead, to replace the fingerprint sensor, is the same with two extra steps (but still need to swap the flash and ‘speaker grommet thingy' as well as the fingerprint sensor):
How remove that tape with the metal frame from the camera? Next to a fingerprit. I need remove and place to new back cover
