Should you need to perform a factory reset on your XR Elite, there are 2 different methods to do so:
From the XR Elite Settings Menu:
Follow the directions here to perform the reset procedure via Settings from within the headset.
Manually via Bootloader
If you are unable to perform the reset procedure via the settings menu, it can be performed via bootloader by following these steps:
a. From a powered off state, hold both the volume down buttons (see number 6 in the below diagram), and the headset button (see number 1 in the below diagram) until the display powers on. Once the display is on, continue to hold volume down, but release the headset button.
b. When the "htc download mode" screen appears, release the volume down button.
c. Use the volume down button to navigate to "factory reset".
d. Once "factory reset" is highlighted, press the headset button on the headset to confirm.
Important: Factory reset will remove all data from the headset, including images, videos, and other files, downloaded apps, your accounts, system settings, as well as save data and other types of personal data. Be sure to back up any data and files you want to keep before you perform a factory reset.
