If your OnePlus 8 smartphone isn’t turning on, use this guide to replace the Motherboard.
Before using this guide, inspect the smartphone to see if the battery or the CPU is faulty. Be sure to test by connecting a computer with your device to confirm that the faulty part is coming from the OnePLus 8's Motherboard (If the CPU is defective, it won't be detected by the device manager).
The Motherboard is the main circuit board that connects and powers all of the internal components, allowing them to communicate. A shorted Motherboard won't allow the phone to be turned on.
Before you begin, please make sure to power off the phone completely and disconnect it from any external power source.
