This video is a tutorial to teach you how to install .deb files on Nokia N9 using the hard way (first time only) and the easy way for the rest of the installations! In order to achieve the easy way, you have to install a file manager using the hard way only for once! you can get some file managers here: Filebox - http://www.n9fanclub.com/2011/10/filebox-file-managment-app-nokia-n9.html QAD File Manager - http://www.n9fanclub.com/2011/10/qad-file-manager-nokia-n9-meego.html File Manager Beta - http://www.n9fanclub.com/2011/10/file-manager-beta-meego-harmattan-12.html In this tutorial, i'm using the QAD file manager, but personally i prefer File Manager Beta Try to rename the files to something short without spaces (like Qadfilemgr.deb ) in order to eliminate the "installation package not found" error on Nokia N9 MeeGo Smart Phone.
