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.
From the home screen, press the Menu key.
Tap All settings.
Under the 'General' tab, tap Backup & reset.
Tap Factory data reset.
Tap Reset phone.
Tap Erase everything.
If unable to reset the device using the above steps, try the Alternate master reset method by first powering the device off.
Press and hold the Power/Lock and Volume-down keys until the 'FACTORY HARD RESET' screen displays.
Press the Power/Lock key.
Press the Power/Lock key again to confirm and initialize the reset.
