Nokia Software Update (NSU) is a program used to update the firmware of a Nokia phone, with the aim of adding new functions that may be available, as well as being able to add new applications and improve performance, fix errors, and so on.
The phone must be connected to the PC via the USB cable, in the same way as to transfer content using the Nokia PC Suite. The application detects the model and alerts you if updates are available for the model. For newer phones you can upgrade your phone system from the new Nokia Suite application; To do this you must select: Tools> Software update.
