This guide demonstrates how to safely remove and replace the motherboard (logic board) in a Samsung SPH-M360 flip phone.
A motherboard replacement may be necessary if the phone has stopped powering on, frequently freezes, or has sustained liquid or impact damage that affects performance.
Before beginning this repair, make sure the phone is completely powered off and that you’re working on a clean, static-free surface to avoid electrical damage. You’ll need only a few basic tools and a careful touch to complete this process in under 20 minutes.
Caution: The logic board is delicate. Avoid using metal tools when prying or disconnecting cables to prevent short-circuiting or breaking connectors.
Note: You’ll need a Phillips #00 screwdriver and a plastic opening tool. A magnetic mat or tray is helpful for keeping screws organized during the process.
