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.
