Introduction
Use this guide to replace the motherboard in your Samsung Galaxy Tab S7+
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.
