Standard Fanvil X303 Reset Methods

Method 1: Reset Through Settings Menu

The easiest and safest method for devices with a working keyboard:

1. Press Menu on the main screen
2. Go to Settings → Factory Reset
3. Confirm the reset by entering the current administrator password
4. Wait for the device to reboot

Important: This method is only available if you have access to the settings menu and know the administrator password.

Method 2: Reset on Power-On

The classic physical method for most Fanvil devices:

1. Turn off the phone completely
2. Hold the OK button while turning on the power
3. Wait for the “Factory Reset” message to appear
4. Press OK to confirm the reset
5. The phone will reboot with factory settings

This method is particularly effective when the standard web interface reset is not available.

What to Do in Unusual Situations

Situation: Keyboard Locked, Password Lost

If your Fanvil X303 has a non-standard password and the keyboard is locked, use one of the following methods:

Method 1: Keyboard Code Reset

According to research from 3CX Forums, a special sequence works for some Fanvil models:

#****#*

Enter this code on the locked keyboard and confirm the reset.

Note: This method may not work on all models and firmware versions.

Method 2: Reset Through Flashing

With complete device lockout, a reset through recovery mode may be necessary.

Situation: Web Interface Password Lost

According to VoIP Expert, the default password for the Fanvil X303 web interface is:

• Default: admin
• Username: admin

If you changed the password and can’t remember it, access can only be restored through a physical device reset.

Recovery Mode and Device Flashing

Accessing Recovery Mode

As research from Yellowgrid shows, the Fanvil X303 can enter Android recovery mode:

1. Turn off the device
2. Turn it on and immediately hold down the volume up and OK buttons
3. Wait for the Android Recovery Menu to appear
4. Use the volume buttons for navigation
5. Select “Wipe data/factory reset”
6. Confirm the reset with the OK button

Important: This method is similar to the procedure for Yealink devices and may be necessary for serious firmware issues or complete device lockout.

Flashing Device Through Recovery Mode

If standard methods don’t work, a complete reflash may be required:

1. Prepare the latest firmware for Fanvil X303 from the official website
2. Place the firmware on a USB drive
3. Connect the USB to the phone
4. In recovery mode, select the “Apply update from external storage” option
5. Select the firmware file
6. Wait for the installation to complete
