Step 1 | Heat the back cover

Apply iOpener to back cover for 3 minutes to loosen adhesive.

Use a hair dryer, heat gun, or hot plate as alternative, but be careful not to overheat the phone.

Risk of heat damage to display and internal battery if overheated.

Step 2 | Insert an opening pick

Secure a suction handle to the bottom edge of the back cover, as close to the edge as possible.

If the back cover is cracked, the suction handle may not stick — try lifting it with strong tape or superglue in place and allow it to cure before proceeding.

Lift the back cover with the suction handle to create a small gap between the back cover and frame.
Apply more heat if needed, following iOpener instructions to avoid overheating.

Insert an opening pick into the created gap.

Slide the opening pick to the bottom left corner to slice the adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.

Step 3 | Slice the adhesive

Insert a second opening pick at the bottom edge of your phone.
Slide the pick to the bottom right corner to cut through the adhesive.

Leave the opening picks in place to prevent resealing of the adhesive.

Step 4 | Slice the adhesive

If the adhesive hardens, it may be due to cooling down.

Reheat the iOpener for 2-3 minutes and apply.

(Note: Reheating will help maintain a workable temperature)

Insert a third opening pick at the bottom right corner of your phone.

Slide the opening pick along the right edge to cut the adhesive.
Leave the pick in the top right corner to prevent resealing.

Step 5

When slicing near the camera assembly, use only the tip of the opening pick (approximately 4-5 mm) to avoid damaging or smearing the camera.

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

Step 6

Insert opening pick under bottom left corner.

Slide along left edge to slice remaining adhesive.

When slicing near power button, only insert ~3-4 mm of opening pick tip to avoid damaging power and volume button flex cable.
