Remove the SIM card tray.

The SIM card will fall out easily; take care not to lose it.

• Alternative options: use a hair dryer, heat gun, or hot plate, but avoid overheating - damage risk exists to display and internal battery.

Apply a suction cup to the phone's back, near its center.

If the display is cracked, covering it with clear packing tape may aid suction.

• For stubborn displays, apply strong adhesive instead or attach the suction cup with superglue.

Pull the suction cup with steady force to create a gap between the back cover and frame.

• Insert an opening pick into the gap.
• Reheat and reattempt if necessary, due to tight tolerances.
• Apply additional heat before retrying if a gap cannot be created.

Avoid applying excessive force with the pick; it may crack the back cover glass.

Slide the pick back and forth along the bottom edge to slice through the adhesive.

Avoid cutting near the corners, where the curved glass can crack if damaged.

• Leave your opening pick in the seam to prevent re-adhesion.

Apply a iOpener to the left edge of the back cover and heat it for 2 minutes.

Avoid excessive force on the pick to prevent damaging the glass.

• Attach a suction cup to the phone's back, near the left edge center.
• Pull firmly with steady force to create a gap between the cover and frame.
• Insert an opening pick into the gap, ensuring its tip is under the glass edge.

Due to tight tolerances, this may require multiple attempts.

• If a gap doesn't form easily, apply more heat and try again.
• Using high concentration (over 90%) isopropyl alcohol in small amounts can aid adhesive loosening.

Insert the pick further into the gap between the back cover and glass.

• Tilt the pick downward while holding it in place.
• This will help loosen the adhesive that holds the back cover on.

Slide a pick along the left edge of the phone to separate the back cover's adhesive.

• Beware when sliding across the ridge surrounding the volume and power buttons, as the cutout in the glass may make it more prone to cracking.
• Leave your pick under the left edge of the glass to prevent resealing of the adhesive.

Apply a iOpener to the right edge of the back cover for 2 minutes.

• A heated hair dryer, heat gun, or hot plate may also be used.

Be cautious not to overheat the phone — heat damage risks display and internal battery.

Apply a suction cup to the back of the phone near its center on the right edge.

• Pull on the suction cup with strong, steady force to create a gap between the back cover and the frame.
• Insert the point of an opening pick into the gap.
• Tilt the opening pick downward to fully insert it underneath the back cover.

Slide a pick along the right edge of the phone to separate the back cover's adhesive.

• Leave the pick under the right edge of the glass near the top for further disassembly.
• If other picks are dislodged, set them aside as they may re-adhere at a later step.

Heat a iOpener and apply it to the top edge of the back cover for 2 minutes.

Be gentle when handling the curved glass near the back cover corners to avoid cracking.

• Slide a pick along the right edge of the device, starting from the top right corner.
• Continue slicing along the top edge to the left edge, separating the adhesive as you go.
• If slicing becomes difficult, stop and reapply heat before resuming.

Remove the back cover by lifting it slowly and using opening picks to separate any remaining adhesive.

• Test all phone functions by powering on your device before resealing.

• Power down your phone completely before continuing work.

• Remove adhesive chunks using tweezers or fingers, and apply heat if necessary to separate the adhesive.
• If using custom-cut adhesives, follow the specified guide.
• If using double-sided tape, consult the provided instructions for reassembly.
