The HTC One M9 has anti-theft and may affect how customers are able to master reset the device. To use anti-theft, follow these steps:
- At least one Google account must be set up on the device.
- The device must have a screen lock (password, PIN, or lock pattern) enabled.
- Once a screen lock and a Google account have been set up, the device is automatically protected against unauthorized factory reset.
- The reset protection features will be disabled if the Google account is removed from the device or the screen lock is disabled.
