Introduction
When pressed, the power buttons relay messages to the motherboard to start up the device or to control the volume of the speakers. Broken or faulty power buttons won’t transmit these signals to the motherboard causing the phone not to respond to the commands.
Before using this replacement guide, make sure that no debris is lodged between the buttons and the phone as it will prohibit the signals from the buttons to be observed. Loose connectors to the power buttons can also result in disruption of the relays sent to the motherboard. Be sure to check out the troubleshooting page to see if a solution can be found without a replacement.
The first step in this replacement process is to remove the back panel of the phone, which is made out of glass. Make sure to be careful removing it that you do not shatter it.
Make sure to turn the device off and to unplug any outside power sources before starting the replacement.
What you need
Step 1
Back Panel
- Turn on the heat gun to a low heat and and gently heat the curved edges on the back of the phone.
- Be careful not to overheat or melt the plastic; heat guns can get out of hand quickly!
- Wedge the opening picks between the front and back panel and slide them around the perimeter to break the adhesive securing the back cover.
- Repeat until the back panel is fully released.

Midframe
- The midframe is made of plastic and located above the battery space.
- Using the Phillips #00 screwdriver, remove the ten 3 mm screws from the midframe.
