Recovery Mode on Yealink IP phones

handset to verify the current firmware version.

For W80DM/W80B

For the W80DM/W80B, there is no screen to show information for you. The W80DM/W80B uses

192.168.0.23 as its default IP address, so you need to configure a static IP address for your local PC

where you have the TFTP server installed.

Procedures:

It must be configured as below:

2. Click OK twice to save the settings.

3. Long press and reconnect the power adapter to trigger the recovery mode.

The W80DM/W80B will download and upgrade the firmware from the TFTP server.
