Secure a suction handle to the bottom edge of the back cover, as close to the edge as possible.

If the back cover is badly cracked, apply clear packing tape over it for better suction or use strong tape instead. As a last resort, superglue the suction cup to the broken cover.

• If needed, apply more heat to soften the adhesive further, following iOpener instructions to avoid overheating.

Insert an opening pick into the created gap.

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

Leave the opening pick in place to prevent resealing of the adhesive.

Insert a second opening pick at the bottom edge.
