After installing it on your device, simply hit the ‘UNROOT’ button and allow Root Access when asked to give it permission. The device will then reboot and you will be completely Unrooted when you boot back up.
Please note that app isn’t free on Play Store, however, it is quite useful if you really decided to Unroot your device and get back official firmware update or a warranty return. If you’re new to Androsphear and want to know what is rooting means, in simple words, ‘Rooting’ your phone gives apps access to parts of the OS that are normally hidden from consumers. This enables you to run software that is more powerful and install custom ROMs on your phone.
