There are two types of resets that you can perform on nabi - forced reboot and factory reset. In the unlikely event that your nabi becomes unresponsive, you can easily perform a forced reboot. A factory reset is recommended when slow performance persists or if you want to wipe out all of your personal data and settings from nabi. Forced Reboot: To perform a forced reboot, hold the Power Button down until nabi turns off. When nabi is off, press the Power Button to turn on nabi again. Factory Reset: Caution! A factory reset is a very serious process because it will SYSTEMATICALLY WIPE ALL USER DATA from nabi. A factory reset will return nabi to its original factory settings.To perform a factory reset from Mommy/Daddy Mode, tap All Apps > Settings > Backup & reset > Factory data reset > Reset tablet > Erase everything.
