Rebooting, Updating Firmware, Factory Reset

If your phone is malfunctioning or require updates you or your phone system administrator may want to perform one of the following:


Rebooting: This will bring the phone back to its last configured state. It is also required sometimes when TeleConsole settings have been updated such as after modifying TeleConsole BLF settings.


Upgrading the firmware: Firmware is the software that loads when the phone is started and controls its functionality. Upgrading it to a newer version when one is released may resolve or improve phone performance issues. 


Factory reset: This erases the current configuration and applies the original configuration the phone was shipped with from the factory. You can reset the the base station or each individual handset. 


Rebooting


In most cases this can be attempted when your phone malfunctions without much concern. If this fails to solve the problem you can attempt the other two methods.


To reboot from the phone user interface:


  • Navigate to Menu>Settings>Advanced Settings>Reboot.

    If prompted for password enter the default password ("admin") or the current phone's admin password.

  • Press the Enter soft key and press the OK soft key when prompted to confirm rebooting the phone.

    The reboot process should take a few minutes.


To reboot via the web user interface:

 

  • Access the web user interface as explained here.

  • Select the Settings tab on the top and select Upgrade from the side menu.

  • Click Reboot.

    The reboot process should take a few minutes.

Firmware Upgrade


You can update the firmware on either the base or the handset. Firmware files can be downloaded from the Yealink support portal. The file should be stored on a computer or network location that can be accessed by the web interface. 


Before upgrading to the latest firmware you should read the related firmware notes and possibly consult with Yealink's support to ensure there are no compatibility issues or other potential conflicts. If such issues or conflicts do happen after an upgrade you may need to downgrade to a previous firmware version or perform a factory reset.


Checking the Current Firmware Version


You can check the current firmware installed on the base or a handset to see if an update is indeed required. 


To check the firmware from the phone: 


  • Press  , or press Menu>Status.

  • Press  or  to scroll through the list and view the status information.

    The firmware is the 3rd item.

To check the firmware version via via the web user interface: 


  • Access the web user interface as explained here.

  • The firmware version is the first item found under the Status tab (the first page of the web user interface.)

Upgrading the Firmware


When upgrading the firmware it is important that you do not close or refresh the browser running the web user interface. Also, during the upgrade, you must not close any network connections on the device running the web user interface or power the device off. 


To upgrade firmware via web user interface: 


  • Access the web user interface as explained here.

  • Select the Settings tab on the top and select Upgrade from the side menu.
  • Click Browse to locate the firmware file you downloaded from Yealink on your local system.

  • Click Upgrade to upgrade the firmware.



  • The web user interface prompts “Firmware of the SIP Phone will be updated. It will take 5 minutes to complete. Please don't power off!”.

  • Click OK to confirm upgrading.

The phone will reboot once the upgrade is finished.


Factory Reset


Factory reset is only recommended after you have tried all other troubleshooting suggestions since it will delete all your personal configuration settings and reset them to the factory defaults.

  It is advisable you contact us  (if you have an account with us) or your phone system administrator before attempting a factory reset to see if the issues with your phone may be resolved without it and to ensure your phone can be properly provisioned and configured if a reset is indeed required.

    If prompted for password enter the default password ("admin") or the current phone's admin password.

    The reset process may take a few minutes. Do not power off until the phone has started up successfully.
