RE: Fireware update failure
        James,
Thank you for your response. Within my original email, note:
P = (W52P Base) = 25.40.0.15
H = (Handset) = 26.40.0.15
These are the current FW versions.
Handset Hardware Version = 26.0.0.7
Looking at your links for instructions to update, it appears I met the OTA requirements:
"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.
So I am not understanding what is needed to upgrade to current FW ?
Thank you for your attention to this issue.
If needed, does the USB interface / flasher, work using OS X ? PC only ?
What is the minimum required OS version ?
Sincerely,
Michael

What's the base firmware you want to upgrade? Can it be upgraded to this V73 firmware? What's the step you follow to upgrade?

What's your handset hardware? If the version is lower than 26.0.0.6 you can't upgrade it in web interface. You have to do the upgrade through a mini USB cord.
