In order to replace the motherboard, you first need to remove the battery, SIM card, and backing of the phone. In order to remove the backing, you will need a T5 Torx Screwdriver to remove the screws. Once the back has been removed and the motherboard is exposed, you will need to carefully pry it from the phone using the plastic opening tool.
