Factory Data Reset (Powered Off) - HTC One® M9

A factory data reset may help with a blank or frozen screen, apps crashing or freezing, keypad/touchscreen problems, can't hear, device making noises, can't make or receive calls, and device won't sync.

Caution Caution:

  • If the device is responsive and can be powered on, the preferred reset method should be performed.
  • For devices with Android Device Protection turned on, it's imperative Google™ sign-in credentials are known prior to completing a factory reset with the device powered off. If credentials are unknown:
    • Attempt to sign in with any Google account previously used on the device.
    • Reset the password.
  • Perform a factory data reset only if absolutely necessary as it removes all data including:
    • Contacts
    • Email accounts
    • System and app data
    • App settings
    • Downloaded apps
    • Media (Music, pictures and videos, etc.)


  1. Ensure the device is powered off.
  2. Press and hold the Volume Down button (middle button located on the right edge) then press and hold the Power button (located on the right edge; first button from the bottom).
  3. Once the HTC logo appears on-screen, release all buttons.
  4. Select factory reset.
    Note Utilize the Volume buttons to highlight and the Power button to select.
    Note If you don't see 'factory reset', the wrong button combination was pressed. Select 'reboot' then begin with step 1.
    Note Allow up to 10 minutes for the factory data reset and reboot processes to complete.
    Note To set up the device after the reset has completed, refer to Initial Activation and Setup.
