Nokia Care Suite is an application that allows you to troubleshoot and flash supported
Nokia devices. By default, it supports GSM, CDMA and WCDMA devices. Besides this, it also includes features to update Nokia firmware.
To use it, connect the phone and the available options will be shown on screen. While the phone is connected, you'll have the possibility to update installed applications, flash firmware, and customize various aspects of the phone.
