I just purchased a W60B base and handset. I also have a W52P handset registered to the base. The W52P handset has a message on the screen - “Old firmware! Please upgrade!”. The firmware version is 26.73.0.11, so I downloaded 26.73.0.30.rom and tried to install via the W60B web admin. It did not report any errors, but the handset has not been upgraded. What am I doing wrong??
