New T25 can't add to Surfboard app

I already activated a T25 with Xfinity and is working well so far.

I want to update to any available firmware version, but can’t add this model to Surfboard Central app, as I did with my old one SB6190.

Any clue how to do it?

Thanks!

The T25 is a modem only device. Nothing to update with it as the firmware comes direct from xifnity with their provisioning.

Great, good to know.

Many thanks!
