A while ago, you bit the bullet and rooted your Android device. The rooting gave you access to plenty of features and apps that you previously didn’t have. You love it.
However, you decide you want to update your Android OS, so you okay the update and watch as the download begins. Once it’s complete, you tap the update button and your device reboots. When the booting process finally finishes, you see the failure message

2. Tap The “Settings” Tab.

5. Read The Confirmation Prompt And Then Tap “Continue”.
6. Reboot Your Device Once SuperSU Closes.
