• Prepare an iOpener or use a hair dryer, heat gun, or hot plate to heat the back panel's bottom edge for one minute.

Apply a suction cup to the heated edge of the back panel by pressing down on it.

• To create suction, press down as close to the edge as possible.
• If the back glass is badly cracked, cover it with clear packing tape for better adhesion.
• Alternatively, use strong tape instead of a suction cup.

As a last resort, apply superglue to the suction cup and attach it to the broken panel.

Apply firm, consistent pressure with the suction cup to create a separation between the back panel and frame.

• If the back panel is stuck, try applying extra heat around the edges before attempting again.
• Once a gap has formed, carefully insert an opening pick into the space.

Insert an opening pick at the bottom of the device.

• Slide the pick towards the left corner to start slicing the adhesive.

Insert a third pick at the bottom of the righthand side.

• Slide the pick upwards towards the top of the phone, cutting through the adhesive on the right side.
• Stop when you reach the top right corner and leave the pick in place.

Insert the third opening pick into the top right corner of the phone and gently move it across the top edge to slice the remaining adhesive.

Careful not to damage the edges.
