Recovery mode on Yealink IP phones
Overview
This guide shows how to use recovery mode to get your phone ready when it fails to
start up. Yealink IP phones support recovery mode using TFTP protocol only.
Generally, when a Yealink IP phone is powered and connected to the network
properly, it will start up successfully and get ready for you to use. In case, the IP phone
is accidentally powered off when upgrading, the system data in the flash may be
damaged and this make the IP phone fail to start up. Therefore, we strongly
recommend that do not unplug or remove the power when the phone is updating
firmware or configurations.
Getting started
Before using recovery mode to get your IP phone ready. You should obtain the
firmware of the IP phone and rename it, install a TFTP download server.
Preparing the firmware resource file
You can ask your system administrator for the firmware or download it from Yealink
web site at: http://www.yealink.com/support.
The file name of the firmware used for recovery mode is strictly required. For example,
to use recovery mode on SIP-T28P IP phones, you must rename the file name of the
firmware as T28.rom. For more detail about the file name of the firmware
corresponding to the phone model, refer to the following table:
