- Adhesive strips or glue

- Replacement LCD screen assembly (including digitizer and glass)

- Use a plastic pry tool to gently separate the back cover from the frame.

- Carefully disconnect any cables connecting the screen to the motherboard, noting the location of each connector[1][10][19].

Step 3: Heat and Remove the Damaged Screen

Step 4: Clean the Frame

Step 5: Transfer Components (If Needed)

- This step may require heating and patience to avoid damage[1].

Step 6: Install the New LCD Screen Assembly
