Dismantle your Qualcomm phone.
Qualcomm is an electronics manufacturing company that has been making parts for mobile devices since the early 90s. Many mobile phones, PDAs and smartphones use technology developed by Qualcomm. This includes everything from circuit boards to processors to antennas. Disassembling your Qualcomm phone allows you to repair, replace and troubleshoot hardware inside your phone. Doing so may void your phone's warranty.
Instructions
1. Hold down your phone's power button for about three seconds until the device powers off. Place the phone face down on a flat surface. Remove the back cover and the battery revealed by the cover.
2. Remove all Phillips-head or Torx screws from the back of the phone. This includes any screws fastening the back casing and main circuit board in place. Use a thin flathead screwdriver, guitar pick or credit card to pry the back casing from the rest of the phone. This reveals the entire circuit board.
3. Remove the remaining screws fastening the circuit board in place. Disconnect all cables from the circuit board. Be gentle when disconnecting these cables. It is easy to break the circuit board if you're not careful. If this happens, your phone may not work.
4. Lift the circuit board out of the phone's casing carefully. Disconnect any ribbon cables from the connectors on the opposite side of the board. Remove the circuit board from the phone.
5. Remove any remaining screws fastening the LCD screen and keypad to the phone's front casing. Remove the LCD screen and keypad from the phone.
