4. Select Reset to Factory Default
5. Confirm the action by entering the administrator password (default: admin)

1. Disconnect the phone’s power from the source
2. Press and hold the # button on the keyboard
3. Reconnect the power while still holding the # button
4. Hold the button for 10-15 seconds until the message “Reset Factory Settings” appears

Recovery Mode Method

When standard methods don’t work (for example, when a password is lost or the keyboard is locked), recovery mode is used, which requires physical access to the device and console connection.

Entering Recovery Mode

To access Fanvil X303 recovery mode:

1. Turn off the device power
2. Connect a console cable (typically RS-232) to the port on the back of the device
3. Use a terminal program (PuTTY, Tera Term, etc.) with parameters:
   • Speed: 115200
   • Data bits: 8
   • Stop bits: 1
   • Parity bit: None
   • Flow control: None
4. Turn on the device power
5. During boot, a command prompt will appear

Forced Reset Commands

Note: As stated in the official Fanvil documentation, recovery mode allows you to perform a reset even with lost passwords.

3. At the command prompt, execute: factoryreset
4. After resetting, use standard credentials:

Device Keyboard Locked

When the device keyboard does not respond to presses:
