WD TV LIVE Theme?

all works fine but after the upload the theme doesnt apply correctly just changes a little bit the menu and thats all! and when go into setup-appearance-theme it doesnt display correctly the theme i just upload, i mean it displays it like the default theme. i tried, the legacy theme from that thread  http://community.wd.com/t5/WD-TV-Live-Hub-Themes/Legacy-Theme/m-p/366519/highlight/true#M6339 joeysmyth answer, second link.

And one more question if finally i change theme eventually, i will take the firmware updates just like before?
