W52P Yealink Firmware Upgrade - W52P Brick - Not Getting IP

In theory, the handset and the base go together. Plug in the base and the handset works with that base.

ADD W52P HANDSET TO BASE

However, you can add the handset to another base if needed:

  • -press the button on the base.
  • -press REGISTER on the phone set.

Long way:

  • -login to the base web page.
  • -click ACCOUNT (at the top).
  • -select ACCOUNT1, ACCOUNT2, ACCOUNT3, ACCOUNT4, ACCOUNT5
  • -fill in the necessary information

FACTORY DEFAULT YEALINK W52P

To factory-default the base:

  • -unplug power.
  • -hold in the button (there's only one button).
  • -plug in the power.
  • -all 3 led's will light up.
  • -unplug power.
  • -plug power back in.

UPGRADEYEALINK W52P

In normal circumstances, the firmware of the base and the handset can be updated here:
http://support.yealink.com/documentFront/forwardToDocumentDetailPage?documentId=25

The firmware of the base can be updated via the web.

The firmware of the handset can be updated via the web (if the base firmware is new enough). Or the firmware of the handset can updated via usb. This requires the usb tool here:

UPGRADE YEALINK W52P BRICKED / NOT RESPONDING

In some cases, there is still no response after the factory default or if the firmware upgrade was incomplete/corrupt. The base needs to be put in recovery mode and is look for a tftp from 192.168.0.23.
