Introdução
This repair will be going through removing and replacing the motherboard of a Nokia 5310b Xpress Music device. It is important to have a working motherboard in the device because it connects and controls the most essential electronic pieces of the device. A damaged or flawed motherboard will result in the device failing to turn on, not charging, not displaying clearly, having random freezes, or showing error messages. This can be caused by harsh handling of the phone, excessive water damage or simply a defective piece of the electronic.
Before using this guide, you can ensure that the problem is a resultant of the motherboard by replacing the battery or trying a different charger to see if that fixes the issue first.
To complete this guide you must be able to remove a screw with a screwdriver and use a spudger properly.
Before removing and replacing the motherboard, make sure that the phone is powered off and not connected to a power source (for example: charging).

Step 5 and 6 must be performed before step 3, otherwise, you will dislodge the thread from the front plate. so you have to remove the camera cover first, remove the 2 screws then you can remove the front plate without breaking anything.
