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 rear glass 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 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.

Insert a fourth opening pick underneath the top left corner of your phone.
Slide the opening pick along the top edge to slice the adhesive.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

Insert a fifth opening pick underneath the top right corner.
Slide the opening pick along the right edge of the rear glass to slice the remaining adhesive.
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 lift to rear glass upwards whilst pressing down the camera cover with a finger.
The camera cover and fingerprint assembly should separate from the rear glass during this procedure. In case the adhesive is too strong, you can apply a heated iOpener to the camera cover for one to two minutes to loosen its adhesive.
Remove the rear glass.
Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
Secure the new rear glass with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

Insert the pointed end of a spudger into the gap next to the fingerprint connector cover.
Use the spudger to pry up the connector cover by tilting the spudger downwards. This might require some force.

Use a pair of tweezers to remove the fingerprint connector cover by pulling it out of its routing and in the direction of the power and volume buttons.

Use a spudger to disconnect the fingerprint reader cable by prying the connector straight up from its socket.

Use a Phillips screwdriver to remove the ten 3.9 mm-long screws securing the motherboard cover.

Slide an opening pick underneath the black foil covering the battery and interconnect cable.
Use the opening pick to carefully separate the black foil from the battery and the interconnect cable.

Insert the tip of an opening pick underneath the bottom right corner of the motherboard cover.
Slide the opening pick along the right edge of the motherboard cover to unhinge the plastic clips and pry it up.
