Samsung Galaxy Note20 Motherboard Replacement

简介

Use this guide to replace the motherboard on your Samsung Galaxy Note20.

For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

Depending on the age of your phone, this may be difficult. If you are having trouble, apply more heat to the edge and try again.
