I have a problem with Openvix 6 5 002

I have a VU+ Uno 4K SE

With older versions of Openvix, the network/Ethernet works and I can download plugins and update the software.

As soon as I update, the Ethernet stops working.

I have downloaded Openvix 6 5 002 and flashed it. Because now there is no Ethernet, I can't restore plugins.

Am I doomed to be stuck on Openvix 6 4 006 ?

I am thinking this is a software issue rather than hardware, or the Ethernet wouldn't work on earlier versions?

Any suggestions would be much appreciated
