Cloud Ibox 2+ New Image?

So I cant update TS Media from 5.7 and the software update links in Vix aren't working so I'm thinking I need a new image, - currently I have version 3.0, build 806.

Can anyone confirm what the latest image is that will work on this box, where I can download it from, & how I install it - can this be done via FTP through DCC or do I need to USB it?

Thanks
