Nokia N85 .sis application problem! Help!

[Führer]

I just got an N85 Nokia phone. The thing is that I've tried to install the compatible S60 3rd Edition Themes (FP2) as well as other .sis compatible applications but with nothing but failure.

When I'm clicking on the install button, I am getting an "Unable to install!" response!

I've checked the settings and all seems to be properly adjusted. This is getting annoying...

Any help would be appreciated!

ok do this first *#7780# factory default reset.punch this code in as if you were making a phone call. you will not lose any data just a reset and see if the behavior of your phone changes and if you can download themes on it.

or go to menu-installations-app manager-options -settings-and change the software installations to all .

try to install them using pc suite

the applications of the s60 3rd edition must be signed. U cannot install unsigned applications.
Tell me what kind of application you need, i'll try to help.;)

In my opinion, you don't need to do any format or restoring factory settings for now (as lebanesecitizen recommended) but sure you need to go to applications, app mgr, options,settings,software installation All.online cert check off.
