Hub One Firmware Update ?

I reset my Hub One last night via the 192.168.1.254 interface and was alarmed to see the message "updating Plusnet Hub One will erase all user-defined settings". It showed the current firmware as Sagem_PH1 version 4.7.5.1.83.8.217.1.1 and the updated one as "version".

I cancelled the update as I wasn't sure if it was legitimate or not. Surely it shouldn't erase my settings?

My Hub One updated the day after I first switched to fibre but nothing since then.

Plusnet Hub One | Software version 4.7.5.1.83.8.217.1.1 | Last updated 06/01/16

Thanks, it looks as though there isn't a firmware update - so what was the message I was sent all about?

You would never see this message.

The device updates itself with no user input.
