Firmware downgrade
I have a T22 which I am trying to downgrade from:
Version
Firmware Version 7.72.0.51
Hardware Version 5.0.0.61

To:
Version
Firmware Version 7.61.0.80

I am auto provisioning from a Broadsoft pbx which requires this specific firmware.

The upgrade process seems to be running for a minute or two, but after a reboot it is still on 7.72.0.51. I've tried IE, Firefox and Safari, but no luck.

I have experience the problem with T20 as well.

Anything I am missing?
