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

    • If the phone's rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.

    • Lift the back cover with the suction handle to create a small gap between the cover and the frame.

    • Insert an opening pick into the gap.

    • If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Slide the opening pick to the bottom right corner.

    • Lift and remove the back cover.

    • Before installing fresh adhesive and reassembling, remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

    • Secure the new back cover with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply pressure for several minutes to help the adhesive form a good bond, such as by placing it under a stack of heavy books.
