Introduction
This is a prerequisite-only guide! This guide is part of another procedure and is not meant to be used alone.
Use this guide to replace the motherboard in your Samsung Galaxy Tab S7+ 5G after removing the USB-C charging daughterboard.
For your safety, discharge the battery below 25% before disassembling your tablet. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.
There is a significant chance that you may break the unreinforced and fragile display panel during this procedure. Be sure to apply plenty of heat and be extremely careful during the prying stage.
You'll need replacement adhesive in order to complete this repair.
