These are the instructions to unroot Samsung Galaxy Tab S 10.5 WiFi SM-T800. The same guide will help if you have bricked your device. Once you finish the guide, you will have installed the same software and firmware that came on your device when you first opened it out of the box. Likewise, that means no more root access to the root file system. Your device will be more secure and not as vulnerable to malware. However, you no longer have the upside of installing the apps from the Google Play Store that required access to the root file system to work.

REQUIREMENTS

• The following steps are made to unroot Samsung Galaxy Tab S 10.5 WiFi SM-T800. They are not made to unroot any other device. Do not flash the firmware file you find in this guide on a different device or else you risk bricking the device.

BEFORE WE BEGIN

• Download the Samsung USB Drivers for mobile phones from this page here. You will find the link if you scroll down the page.
• Some of you will find that the USB Debugging Mode is already enabled. Nevertheless, you cannot go far without it enabled, so double-check that before starting. You can do that by heading to the Settings > Developer Options > USB Debugging.
• Unrooting Android devices usually restores the warranty. However, some Samsung smartphones and tablets come with added Knox security. These additional security measures don’t allow for a warranty to be restored when you unroot the device. You’ll need to check if your device is a device that does come with Knox security.
