INSTRUCTIONS & INFO

A Master Reset reverts the device back to factory settings. It will permanently erase all personal data, preferences, settings and content such as pictures, ringtones and apps that are saved to the device. Data stored to an SD card will not be erased unless otherwise selected. It is recommended that you save (backup) important data to your SIM, SD card, or a computer before proceeding.
Swipe down from the Notification bar, then tap the Settings icon.
Tap the Accounts tab, then tap Backup and reset.
Tap Factory data reset.
Tap Reset device.
Tap Delete all.
If unable to reset the device using the above steps, try the Alternate master reset method by first powering the device off.
