    • The next five steps show how to loosen the phone's top glass panel in order to access the LCD panel. Before slicing, note the following areas:

    • Thin adhesive bordering the display panel

    • Thick adhesive holding the top and bottom bezels

    • The digitizer cable, which will hinder slicing if hit

  7. Firmly press an opening pick into the right edge seam of the phone, until the point slides in between the frame and the display glass. Firmly press an opening pick into the right edge seam of the phone, until the point slides in between the frame and the display glass.

  9. Continue cutting the adhesive with the opening pick, rounding the bottom right corner and slicing through the bottom bezel area. If you are having trouble cutting through the adhesive, apply a heated iOpener to the bottom edge for a minute before trying again. Push the pick in as far as the bezel's thickness in order to slice through all of the adhesive. Slice around the Home button.

    • The Home button will most likely fall out. Remove it and keep it in a safe location for re-assembly.

    • The top panel is still connected to the LCD display by a digitizer flex cable. Optionally, you can use scissors to cut the flex cable and completely remove the top panel. This will render your old display unusable.

  12. Heat an iOpener and apply it to the front of the phone for a minute, covering as much of the screen as possible. Take note of the following areas when prying the LCD panel:

    • Slowly and firmly press the card inwards, wiggling it as needed, until it slices through the other side.

    • If the slicing becomes hard, you can always reheat an iOpener and apply it to the screen for a minute to help soften the adhesive.

  15. Once the plastic card cuts through the width of the phone, slowly and firmly push it towards the top, wiggling it as needed. Continue until you release the LCD panel from the frame. Apply a heated iOpener to help loosen stubborn adhesive.

Ist es möglich nur das Glas ohne LCD zu wechseln?

RC Addicted - 回复

Yes! The LCD is not glued to the display.

Ja! Das LCD ist nicht mit dem Display verklebt.

What kinds of adhesives can I use to put the new screen on? Double sided scotch ok?

William Crawford - 回复

Hi William,

Double-sided Scotch tape probably will not hold the display on for long. You will have to use something like Tesa tape along the perimeter. If you bought the part we sell in our store, it already has all the necessary adhesive pre-installed on the screen.
