A combination of button presses resets a Nextbook Android device to factory settings. After charging the device and disconnecting from the charger, hold the up volume button while also depressing the power switch. Hold the two buttons until the Nextbook logo appears on the screen. Release both buttons and press the up volume button to display a menu. Navigate to Wipe Data Factory Reset and choose Yes to reset the device.
Resetting a device to factory settings is a last resort for those attempting to fix a problem or to start fresh on a used device. A hard reset this way is necessary whenever the settings menu on the device is inaccessible, whether because of a software problem or a lost or forgotten password. A factory reset, hard or soft, deletes all user records and data on the device, as well as any downloaded apps and purchases. App and purchase information remains at the Play Store for recovery after the reset.
Similar hard-reset mechanisms exist for many Android devices, from smartphones to Chromebooks. The specifics may differ based on device and version of Android, but the reason for performing the rest and end result are the same.
