步骤 3

Use a hair dryer to lightly heat the perimeter of the rear glass.

步骤 4

Apply a suction handle as close to the bottom edge as possible.
Pull up on the suction handle with strong, steady force to create a gap between the glass and the frame.
If you have trouble creating a gap, apply more heat to further soften the adhesive.
Insert an opening pick into the gap.

步骤 5

Slide the opening pick around the perimeter of the rear glass to slice the adhesive.
Insert additional opening picks as you slice the adhesive to prevent the adhesive from resealing.
If the adhesive becomes hard to cut, it has most likely cooled down. Use your hair dryer to reheat it.

步骤 6

Carefully lift the rear glass up and off of the phone.
During reassembly secure the rear glass with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.
