Can't upgrade handset firmwares - simon templar - 06-07-2014 02:37 AM

Hi ,

When I go on the yealink W52P web interface, under PHONE / UPGRADE , I can see:

Firmware Version 25.50.0.20
Hardware Version 25.1.0.0.0.0.0


I downloaded 26.50.0.20 ( Handset Firmware ) from Yealink.com / support / download , and tried to upload it in Handset Firmware (in W52P web interface), but without success.

Any trick for this to work ?

Thank you.

Hi simon templar,

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.
