    To reset a HoloLens so it no longer has the previous owner’s data or account, use the built‑in reset or, if needed, a full reflash.

    1. Make sure the device has at least 20–40% battery and is using a proper charger.
    2. Put on the HoloLens and sign in if it lets you, then:
      • Open Settings.
      • Go to Update & Security > Reset & recovery > Reset this device.
      • Confirm the reset.
      This removes all user accounts and erases all data on the device.

    If the device is locked, not usable, or you can’t get into Settings, a clean reflash can be used instead (HoloLens 2):

    1. On a Windows 10 PC, install Advanced Recovery Companion and download the latest HoloLens 2 image from https://aka.ms/hololens2download.
    2. Ensure the HoloLens is charged to at least 40%.
    3. For normal flashing:
      • Turn on the HoloLens.
      • Connect it to the PC with a USB cable.
      • In Advanced Recovery Companion, select the Microsoft HoloLens device and follow the instructions to complete the reflash.
    4. If the device doesn’t start correctly or ARC can’t detect it, use manual flashing mode:
      • Unplug the USB Type‑C cable.
      • Press and hold the power button for 15 seconds until all LEDs turn off.
      • While holding volume up, press and release power to start the device, keep holding volume up for 15 seconds, then release.
      • Connect to the PC and, once ARC detects the device, follow the on‑screen steps to install the image.

    Warning: Resetting or reflashing erases all personal data, apps, and settings on the HoloLens.
