Unable to update Firmware from 66.83.0.55
Hello,

I have 8 T42s Phones and 2 T48s phones, all running firmware 66.83.0.55

We have tried to upgrade the firmware, but the phone just reboots back to the same 66.83.0.55

We have tried to go up a single release, down a single release.
The odd thing is that the yealink website doesn't list 66.83.0.55.
It's as if that firmware never existed...

Any Ideas?
