I'm starting to create a few guides which will help the NORMOB's (normal mobile user) and mobile enthusiasts alike. There are two reasons for this; a) helps me moderate the Mobile9 Forums making life much easier for myself and the other moderators and b) to help the general mobile user.
My first guide will be aimed at showing the users with branded handsets how to change upgrade their firmware and change to an unbranded generic version.

I will state that you follow this guide at your own risk, your handset may become void from warranty and there is always a small chance things could go horribly wrong. So please do not hold me responsible for any ill fated results that may occur.

This guide will work on Nokia N95-1 (European version) and may work on other N95 variants.

Firstly the tools of the trade required to follow this guide (I will be doing this on the presumption you are running a Windows set-up):

• Nemesis Service Suite
• Nokia Software Updater
• Nokia Pc Suite
  
• USB Cable (that came with your handset)
• Access to the Internet
  
• A bit of techno savvy and guts
  

Firstly, download and install Nemesis Service Suite, Nokia Pc Suite and the Nokia Software Updater (the Nokia Software Updater may come bundled with the Nokia Pc Suite). Make sure your handset is fully charged.
Plug the handset into the USB cable and put it into "Pc Suite" mode.
Run the Nemesis Service Suite, you should be presented with the following screen:



Clicking on the little magnifying icon will scan your handset and NSS will display the information on screen. You can click along the tabs and clicking "SCAN" will show the various sources of information relating to your handset. Do not start to mess around with anything if you aren't sure about anything.
Click on the "Phone Info" tab and hit scan to get your IMEI number and your "Product Code" the latter which we are interested in. Tick the box next to the Product Code area where it says "Enable" see screenshot below for more info.



Next we need to find a generic product code for your handset. AllAboutSymbian have a thread with collection of product codes for the N95-1. I would suggest using either the EURO1 - Sand (0534851) or EURO1 - Plum (0536062)to be on the safe side. Simply enter the code replacing the old product code and hit the write button. This will instantly replace the old product code with the new product code entered.

Next step is to close down the NSS and start-up the Nokia Software Updater. Follow the prompts on screen to scan for the latest firmware and upgrade. The Nokia Software Updater will download the latest firmware for the product code entered and update your handset. This can take up to an hour depending on your internet connection. Do not disconnect your handset from the USB cable as this may harm your handset whilst the update process is running.




Once the Updater is done you can unplug it and re sync your data back to the model and reconfigure your device and enjoy the latest generic firmware on your handset and enjoy the handset as it was originally meant to be.

No more Operator Branding. Enjoy!

*Note- This Guide is aimed at N95-1 (original release)
**Also Note - Do not restore backup from a different product code, do your backup after changing product code
