Completely power off your phone before disassembly.

• iOpener: Heat for one minute on left side of rear cover.
• Alternative: Use a hair dryer, heat gun, or hot plate, but be cautious not to overheat and damage the screen or internal battery.

Risk of damage to internal components if the opening pick is inserted too far.

• Apply a suction cup to the heated edge, as close to the edge as possible.
• If the back glass is badly cracked, cover it with clear packing tape for better adhesion.

Superglue can be used in extreme cases if other methods fail.

• Apply strong, steady force to create a gap between the rear cover and frame.
• If necessary, apply more heat for assistance.

Insert an opening pick into the gap, but no more than 5 mm deep.

Insert an opening pick into the device at the top right corner, and then slide it down the left edge toward the bottom left corner to break the adhesive.

Leave the pick in place to prevent the adhesive from re-sealing.

Do not insert the opening pick more than 5 mm into the phone.

• Repeat the process of heating and cutting along the three remaining sides.
• Insert each new opening pick in gaps created by previous picks, leaving one in each corner.
• Slide an opening pick around the perimeter to release any missed adhesive.

Reheat stubborn adhesive as needed to prevent re-sealing.

Remove the rear cover by lifting it straight up.

Pry under the edge of the wireless charging coil press connector to avoid damaging the socket and surrounding components.

• Use a spudger's pointed end to pry up and disconnect the press connector.
• Re-attach by carefully aligning and pressing down on one side until it clicks, then repeat on the other. Do not press in the middle.

Locate the white press connector at the bottom right of the motherboard shield. Use the pointed end of a spudger to carefully pry it up and disconnect.

• Remove the six 4.0 mm Phillips screws securing the motherboard shield using a Phillips screwdriver.
• Label and keep track of each screw for correct reinstallation.

Handle the motherboard shield carefully — its edges are thin and sharp.

• Use a pair of tweezers to lift up the motherboard shield.
• Grip the motherboard shield with your fingers.

Peel the wireless charging coil upwards, carefully prying it loose from its adhesive mounting.

Be gentle when removing the coil as it may be stuck firmly in place due to the light adhesive.
