How do I factory reset my UMX U673C phone?

To perform a hard reset on your UMX U673C:

Power off the phone completely.
Press and hold Power + Volume Up buttons until the UMX logo appears.
Release both buttons briefly, then press them together again for one second.
When the “no command” screen appears, press Power + Volume Up simultaneously once more to open the recovery menu.
Use Volume Down to navigate to “Wipe data/factory reset” and press Power to select.
Navigate to “Yes” using Volume Down and confirm with Power.

Important: After reset, you’ll need the Google account credentials previously used on the device due to Factory Reset Protection. If you don’t have these credentials, contact the previous owner or Google support.
