install s40 theme on rda: not working?

[ELyrae]

I', tried 3 or 4 time to install a theme on s40 RDA (c3 and asha), made theme with compact ui plugin, uploaded it but:
nothing happens!!
Install will not start on phone and no errors appear....simply NOTHING happens...why?

I assume you have created the theme only using .png images , as rendering of other image formats is unknown. Please attach the .nth theme file.

The problem is in the description of how to install on s40 device, using "install" in the rda menu dosent work.
Instead I open the file manager, upload theme to "defaultthemes" on the device and that's it!!
