You will need:
a. Nokia PC suite installed (www.nokia.com to download or disc supplied with your phone)
b. Nokia USB cable (as supplied with your phone)
How do you do it?
You need to be connected to your PC (use your Nokia USB cable as provided with the phone) and have Nokia PC Suite running and your phone recognised.
Switch off any Anti Virus and disable any firewall!!!!!
Firstly you will need to Sync your stuff with PC Suite.
DO NOT use backup and restore as this has shown to cause future problems with stability!
If you need your texts message for reference then change the message settings to save on your memory card and you get the option to copy across all existing texts.
You will also 'loose' all your installed apps and will have to reinstall these once you have completed the Debrand/upgrade process.
You will also need all your network and internet (data) access settings. You can note them down, get them resent after the debrand/upgrade to your phone by text message from your network provider or from Nokia, or for UK simply get them from here http://www.filesaveas.com/networks.html.
Download and install the latest Nextgen server client, this will put a copy of the drivers on your PC
1. Run Client
2. Enter your User name & Password under “username & password” tab
3. Click on “server settings” make sure “main server” is selected
4. in “phone settings” select “Nokia” from drop down list.
5. in “nokia jobs” select “chg. ProdCode”
6. Click “Do Nokia Job”
7. Select the New product code (only products codes for your type of phone are displayed, descriptions are also displayed)
8. Double click the product code you whant, Nextgen Server client will now update your phone
Now to Update the firmware in your Phone, Make sure your battery is fully charged.
Go back to Nokia Data Suite and Click the 'Update phone software' button and the programme will lead you through the process of update. You may be required to download and install a newer version of the 'Nokia Software Updater' so just agree and wait for this to complete.
The NSU (Nokia Software Updater) will start and give instructions! (you maybe redirected to the Nokia website to download the Nokia Software Updater if you have not done so previously) It will detect your phone, identify it and search for an available update. Then, if one is available, it will give the option of proceeding with the update. Say yes and once the update has started wait until the process has finished.
Do not touch the phone, do not turn it off, do not disconnect the USB cable.
When the update has finished your phone will restart and you will have installed the latest firmware version of the Operating System.
At this point it does no harm to do a hard reset (see below) just to be sure you have what is referred to as a 'vanilla' phone.
Now re-sync with PC Suite and re-enter your network access and data settings.
Finally, re-install your applications to the phone memory (if you use the card memory you can get problems and power consumption goes up so less battery life!
