简介

Problems may occur with the home button if there is dirt or something that is damaged underneath the button. In this guide, you will learn the steps to remove the back panel and lower motherboard of the phone to isolate the home button, clean the area around the home button, and replace the home button. When removing the back panel use the proper tools to avoid cracking the screen or damaging any other part of the device.

    • Using your fingernail or any prying tool (we used the Metal Spudger), begin to pry away the back panel starting at the bottom of the phone.

    • Continue to work your way around the phone counterclockwise until you can pull the back cover off.

    • Unscrew the twelve 3 mm screws from the back panel using a Phillips #00 screwdriver.

    • Keep these screws in a safe place. They are very small and easy to lose.

    • Using the plastic opening tool, create a small gap between the front screen and the metal casing. Slide the plastic opening tool around the phone counterclockwise to make this gap around the entire phone.

    • Once the screen is separated from the back panel, pull the two pieces apart.

    • The lower motherboard will still be attached to the front panel by a red and blue cable on the left side and a long silver wire on the right side, but you should now have visibility of the home button.
