Unplug your phone and power it off.

• Apply an iOpener to the back cover's bottom edge for 2 minutes.
• Alternatively, use a hair dryer, heat gun, or hot plate, but be cautious not to overheat: the display and internal battery are prone to damage from excessive heat.

Do not apply excessive force with the opening pick.

• Apply a suction cup to the back of the phone's bottom edge, as close to center as possible.
• If the display is badly cracked, cover it with clear packing tape for better adhesion.

Tight tolerances may require multiple attempts: apply heat and separate with suction cup.

• Insert an opening pick into the created gap, if one forms.
• If no gap is formed, reapply heat and try again.

As a last resort, superglue the suction cup to broken glass.

Avoid cutting the adhesive near the curved corners, as this may damage the glass panel.

• Slide a pick along the phone's bottom edge to carefully slice through the adhesive.
• Remove your opening pick from the seam and leave it in the gap you have created to prevent the adhesive from resealing.

Heat an iOpener and apply it to the left edge of the back cover for 2 minutes.

Apply a suction cup near the left edge.

• Pull on the suction cup with strong force to create a gap between the back cover and frame.
• Insert an opening pick into the gap, ensuring only the tip is underneath the glass's edge.

Due to tight tolerances, creating a gap may take multiple attempts or applying additional heat.

For assistance, try applying 2-3 drops of isopropyl alcohol (over 90% concentration) into the seam.

Avoid excessive force with the pick to prevent cracking the back cover glass.

Insert the pick slightly under the glass's edge.

• Tilt the pick downwards, increasing its angle to release the adhesion between the back cover and the frame.

Careful not to crack the glass when sliding across the ridge.

• Slide a pick along the left edge of the phone to separate the back cover's adhesive.
• Leave the pick under the left edge of the glass after separation, do not remove it.

Avoid overheating the phone, which can cause damage to the display and internal battery.

• Apply a heated iOpener to the right edge of the back cover for two minutes.
• Alternatively, use a hair dryer, heat gun, or hot plate, but keep an eye on temperature levels to avoid damage.

Apply a suction cup to the phone's back, as close to the right edge center as possible.

• Pull on the suction cup with strong, steady force to create a gap between the back cover and frame.
• Insert an opening pick point 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 to prevent resealing.

• If other picks are dislodged, set them aside as the bottom edge should not reseal from this point on.

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

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

• Slide a pick from the right edge around the top right corner of the device.
• Continue slicing along the top edge, moving clockwise to the left edge.
• Separate the back cover adhesive completely; if slicing becomes difficult, reapply heat and try again.

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

• Test your phone's functions by powering it on during reassembly.

• Power down your phone completely before continuing work to avoid damage.

• Remove any leftover adhesive chunks with a pair of tweezers or your fingers.
• If necessary, apply heat to help separate stubborn adhesives.

• For custom-cut adhesives, follow the relevant guide for application instructions.

• For double-sided tape, consult the dedicated guide for proper installation procedures.

Remove the six motherboard bracket screws using a Phillips #00 screwdriver.

• Note the location and orientation of each screw for proper reinstallation.
• Keep track of the removed screws to prevent mix-ups during reassembly.

Do not damage the wireless charging coil or remove the bracket yet.

• Use a pair of tweezers to gently pull up and unclip the motherboard bracket from the plastic midframe.

The bracket is still attached to the wireless charging coil, so do not remove it yet.

Gently tilt up the motherboard bracket to access the orange battery connector.

Be cautious when disconnecting battery connectors to avoid damaging nearby surface-mounted components.

• Use a spudger to pry up and disconnect the battery connector.
• Avoid dislodging small surface-mounted components surrounding the socket.

Use a spudger to gently pry up and disconnect the wireless charging coil connector.

Use a pair of tweezers to gently remove the wireless charging coil from the device.

• Remove the wireless charging coil completely.
• During reassembly:
• Reconnect the wireless charging coil and battery connectors.
• Refasten the motherboard bracket screws to align everything.
• Firmly press the coil pad down to secure it in place.

Remove the five 4 mm screws using a Phillips #00 screwdriver.

• The screws secure the loudspeaker and lower midframe.

Use a spudger or tweezers to pry the midframe loose, starting from the top left corner.

• Be careful not to damage the midframe clips.

• It may take some force to release the clips.
• Once loose, remove the loudspeaker and separate it from the lower midframe.

Remove the main and auxiliary flex cables using a spudger near the device's bottom.

• When re-attaching press connectors, align carefully and press down on one side until it clicks into place.
• Repeat on the other side; do not apply pressure in the middle.

Pressing a misaligned connector can bend pins, causing permanent damage.
