If the phone gives you an error like "not enough memory" it means that you should first free some memory by deleting content from your phone which you don't need like old pictures, obsolete applications, music, etc.
In case of a firmware change you need to contact local service support for Nokia because it's a complicated operation and doing it by yourself could brick your phone permanently. On the other side you can use Nokia Pc Suite which supports almost all Nokia phones. It has the ability to install/uninstall applications, transfer content to and from your phone and much more. You can download PC suite from our Software Informer website or just by visiting official Nokia PC Suite website by clicking here.
