Requirement

  • Make sure your phone is fully charged
  • Enable USB debugging in Settings > Developer options
  • Have ADB and Fastboot installed on your computer
  • Be sure to back up anything in the internal storage of your device because this process might wipe all data from your device
  • Make sure you have the HTC drivers installed. If you installed HTC Sync, then they are already installed
