Insert the SIM eject tool, bit, or a straightened paper clip into the small hole on the SIM card tray.

• Press firmly to eject the tray.
• Remove the ejected SIM card tray.

Power off your phone completely before proceeding.

• Apply an iOpener to the left edge of the rear cover for one minute.
• Alternatively, use a hair dryer, heat gun, or hot plate; however, be cautious not to overheat the device, as this may damage the display and internal battery.

Apply a suction cup to the heated edge of the rear cover as close to the edge as possible.

• If the rear cover is badly cracked, cover it with clear packing tape for better adhesion.
• Alternatively, use strong tape instead of the suction cup or superglue it in place if necessary.

Pull up on the suction cup with strong, steady force to create a gap between the rear cover and frame.

Depending on phone age, this may be difficult. Apply more heat and try again if having trouble.

Insert an opening pick into the gap.

Slide an opening pick along the left edge towards the bottom left corner to slice the adhesive.

• Do not insert more than halfway into the phone, or you risk damaging internal components.

• Leave the pick inserted in the bottom left corner to prevent re-sealing of the adhesive.

• Repeat heating and cutting for the remaining three sides.
• Leave an opening pick on each side before moving to the next one.
• The rear cover will begin to separate from the phone as you complete all sides.

Remove the rear cover by lifting it straight up.

• To reinstall the rear cover, refer to our separate guide on reassembly and reattaching adhesive.
• Power on your device after repair and test its functionality before sealing with new adhesive.

Do not seal your device until it has passed testing and is fully functional.

For Tesa tape instructions, consult our dedicated guide for reattaching components.
