Upgrading stock firmware in Teltonika RUT955

I've just got hold of a Teltonika RUT955 and trying to get it to connect to the Internet using my Virgin Mobile SIM which works fine in my Android phone.
Since it doesn't recognise Virgin Media I thought I'd upgrade the Firmware....
According to:-
https://wiki.teltonika-networks.com/view/RUT955_Firmware_Downloads
the latest is

RUT9_R_00.07.00

but when I tried upgrading I'm told that this version is older than the current which is RUT9XX_R_00.03.491.

Any suggestions as to what is going on here?

I'm sure Teltronika would know, ask them.

It's their fw.

Yes, there's 3 versions of firmware on the link, your device is using the RUT9XX version, Teltonika should be able to tell you how to upgrade to their new WebUI that is not LUCI
