How to softwear update my 6300 phone - Nokia 6300 Cellular Phone

It's broken, get a new one.

My understanding is all upgrades are available by using the Nokia 'Phone Software Update' available on their support site. If you simply want to upgrade, I recommend using that.
Link to Nokia's support for the 6300 is HERE
Hope that helps.

1. You need download and install NSU - Nokia Software Updater (http://europe.nokia.com/support/download-software/device-software-update/download#) and run it to ensure that all is ok! (don't forget to switch on and connect Nokia 6300 via USB with PC)
2. You need to download and install NSS (Nemesis Service Suite) (http://www.b-phreaks.co.uk/index.php?main_page=page_2), the latest version of NSS was 1.0.38.15 (select "Virtual USB Device" mode)
3. Close NSU if it's not closed and load NSS then click icon "Scan for new device"
4. Click icon "Phone Info" and button "Scan" inside it
5. If all is ok you'll see some lines with Phone Version, Phone IMEI and so on
6. Click button "Read" and remember your "Product Code"
