The next thing you need to do is locate the ‘SW Update’ icon. The screen will show the contents of the Applications tab. Locate and access the ‘Applications’ icon from the main menu.
Then press the ‘Menu’ key on the screen to access the main menu. Following that, connect your device to a WiFi network. And again make sure your battery is charged. If your device is on then it is advised that before the upgrade you restart it.
