I am on 028 on my Vu+ Uno. When I installed that I did the full reflash i.e USB and reconfigure. Then downloaded a settings file, cccam (copying config files), tsmedia, skin, opening logo and that's about it. Works fine
Went through the same procedure with 032 and cccam won't work. Also (and I know it's now not supported) I uploaded a catseye settings (after uploading a previous non catseye settings file) and found that many of the channels were not there.
I've reverted back to 028 at the moment but noticed that there are no downloads listed now.
