WARNING! Master resetting your smartphone will return all settings to factory values, and will remove all personal data stored on the phone's internal memory, including downloaded apps, audio files, custom ringtones, photos, contacts etc. Before proceeding, it's recommended that you back up your data.

NOTE: To learn how you can back up and restore data on the Desire EYE locally or via HTC Backup, click the link.

Master Reset Using the Settings Menu:

  1. While viewing the home screen, tap "Apps"
  2. Go to "Settings"
  3. Swipe to "Personal" and tap "Backup & reset"

  5. Tap "Reset phone"
  6. In case your phone is lock screen enabled, enter the screen unlock information to proceed
