    • Secure a suction handle to the lower edge of the rear glass, 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 rear glass with the suction handle to create a gap between the glass 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 of the phone.

    • Insert a third opening pick at the bottom left corner.

    • Start to slide the opening pick from the bottom left corner along the side of the Xiaomi Mi 9 to cut the adhesive.

    • Be aware of the rear cameras and only insert the tip of the opening pick. As the adhesive cools down it gets harder to cut. If necessary use your iOpener to reheat it.

    • Leave the opening pick in the top left corner to prevent the adhesive from resealing.
