Loading the Jarvis is not as simple as putting oit on a USB stick and loading it. That will not work.
And them instructions posted thru that link give no clue on how to load thru USB onto an avov, nothing to do with avov really.
With the Fuse model, the main screen with the 4 option ICONS and one being Kodi, open that Kodi option and there are 3 versions of Kodi available that can be installed.
-Isengard 15.0
-Isengard 15.2
-Jarvis 16.0
Load any version but just one. If another is loaded this way then I think it will over-wright the last (but I have not tried that).
There is also there on that same menu Kodi install screen, an option to load other addons or maybe apks ( I have not tried this yet either).
Does the TVOnline Plus box have these same menu options ?
There is the 2 versions of Kodi in the Market Store as well..
-Helix 14.2 (TVAddons version)
-Insengard 15.2
And you can even load both of them at same time and they will be seperate entities. Each will wok independent of the other.
I have the two versions on the Vixo2 model here and both work well.
Fuse can do that too, but the Fuse could have 3, when including that Jarvis version thru the Kodi install menu.
Does the Plus models have that same Kodi install menu option ?
