Lightbulb [FAQ] How to upgrade firmware?
This post provides information on upgrading the IP phone firmware.
Two methods of firmware upgrade:
- Manually, from the local system for a single phone.
- Automatically, from the provisioning server for a mass of phones.


The following table lists the associated and latest firmware name for each IP phone model (X is replaced by the actual firmware version).

Upgrade via Web User Interface

T o manually upgrade firmware via web user interface, you need to store the firmware to the local system in advance.
To upgrade firmware manually via web user interface:
1. Click on Settings->Upgrade.(For T3X and VP530, click on Phone->Upgrade.)
2. Click Browse.
3. Select the firmware from the local system.
4. Click Upgrade.
A dialog box pops up to prompt “Firmware of the SIP Phone will be updated. It will take 5 minutes to complete. Please don't power off!”.
5. Click OK to confirm the upgrade

Note
Do not unplug the network and power cables when the IP phone is upgrading firmware.
Do not close and refresh the browser when the IP phone is upgrading firmware via web user interface.


Upgrade Firmware from the Provisioning Server

IP phones support to use the FTP, TFTP, HTTP, and HTTPS protocols to download the configuration files and firmware from the provisioning server, and then upgrade firmware automatically.
IP phones can download firmware stored on the provisioning server in one of two ways:
- Check for both configuration files and firmware stored on the provisioning server during booting up.
- Automatically check for configuration files and firmware at a fixed interval or specific time.

Method of checking for configuration files and firmware is configurable.

Procedure
Configuration changes can be performed using the configuration files or locally.

Upgrade the Base Station

You can upgrade your base station to the latest firmware version. The latest firmware version not only improves the performance of the base station, but also provides more features compared to the previous version. This section provides you with instruction on upgrading the base station via web user interface.

For more information on upgrading the base station via auto provisioning, refer to Yealink W52P IP DECT Phones Auto
Provisioning Guide.


To upgrade the base station firmware, contact your system administrator for the latest firmware file, and store it on your local system in advance.
To upgrade base station firmware via web user interface:
1. Click on Phone->Upgrade.
2. In the Select and Upgrade Base Firmware field, click Browse to locate the firmware file from your local system.
3. Click Upgrade to upgrade the firmware of the base station.
The browser pops up the dialog box “Firmware of the SIP Phone will be updated. It will take 5 minutes to complete. Please don't power off!”.
4. Click OK to confirm upgrading.
The upgrading process will take a few minutes. The power indicator LED on the base station flashes when the base station is during the firmware upgrading process.

Once the base station firmware has been successfully upgraded, the base station reboots automatically. The handset will perform an auto registration to the base station. You can check the firmware version of the base station using the handset.

For more information, refer to Yealink_W52P_User_Guide_V40_15

Note Do not refresh or close the browser during the upgrading process of the base station.

Upgrade the Handset Firmware

You can upgrade W52x handset firmware via a USB tool or over the air (OTA).
Upgrading handset firmware via the USB tool (developed by Yealink), you need to purchase a USB cable in advance, and then upgrade the handset firmware one by one.
Upgrading handset firmware via OTA means that the handset firmware can be upgraded through a wireless DECT connection (L2CAP). So a USB cable does not have to be plugged to the handset for firmware upgrade. OTA enables the distribution of new firmware to the subscribed handsets.

OTA upgrade capability is restricted to specific firmware versions and handset hardware:
* Handset with firmware 26.40.0.15 or later
* Base station with firmware 25.40.0.15 or later
* Handset with hardware 26.0.0.6 or later

OTA is only available when meeting the above three conditions simultaneously.

Upgrading handset firmware may take a period of time, please upgrade the handset outside of work hours to avoid affecting the normal use.


You can refer to Upgrading W52x Handset Firmware for more details.
