These are the instructions to unroot Samsung Galaxy Grand 3 smartphones with the model number SM-G7200. You can follow this guide regardless of your rooting method. As of today, the only rooting method we can find available is using the KingRoot universal one-click rooting application. Subsequently, we are teaching you how to unroot the Galaxy Grand 3 using the KingRoot method.
Furthermore, we are also teaching you how to unroot using a more traditional method by flashing the Samsung Galaxy Grand 3 stock ROM back on the device. By flashing the stock ROM you will be unrooting any future rooting methods by developers such as Chainfire with his CF-Root tool.
- It’s important you only follow this guide if you have the Samsung Galaxy Grand 3 smartphone with the model number SM-G7200. You can find out your model number by tapping on the Menu > Settings > About Device > Model Number.
- You must have a Windows PC to follow this guide. You cannot use the Odin flashing tool on a Linux or Mac computer.
BEFORE WE BEGIN
- Download the Samsung USB Drivers before you start the guide. You want those USB Drivers running on your Windows PC before you start the steps.
- You are about to get your Galaxy Grand 3 warranty working again once you complete this guide. As you probably know, you void a warranty when you choose to customize your device using a rooting method, installing a custom recovery, unlocking a bootloader, installing a custom ROM or custom kernel. That can all be undone provided your device does not have Knox security. You can sometimes find workarounds for not tripping Knox, though it’s often not worth the effort unless you have a rooting method that directly doesn’t trip the Knox security.
