The following is a guide on how to debrand your N95 8GB.
Please note that the information provided for this guide has come purely from research on other sites/forums and my own personal experience.  Please be aware that you run this procedure at your own risk and I’m not to be held liable if anything goes wrong.  I have only attempted to debrand one N95 8GB so far and that was successful hence this guide being posted.  This was easy and only took about 20 minutes max.  Also be aware that there is always a risk of damaging your phone when flashing your firmware.  If this does happen then the only suggestion i have is taking your phone to a Nokia service centre.  Finally performing this procedure will Invalidate any warranty your phone has. Oh yeh… Ensure your phone is fully charged ;-)  (Thanks Carl)

The Guide:
1. Ensure you have installed the Nokia PC Suite supplied on the CD with your phone. Make sure your phone is connected via the USB cable and that it has been detected. Use your Nokia Connection Manager to show if your USB is connected. On your phone click PC Suite when the menu pops up.

2. Download the following 2 pieces of software:

3. At this stage its best to back up all your files. To do this simply use the Backup utility within the Nokia PC Suite. This will back up all your contacts/messages/videos/photos/music.

4. Install Nemesis Service Suite and make sure you select the ‘Virtual USB’ option in the installation wizard. Open the program and click Scan for new Device icon top right of the screen.
The screen will now fill in the blanks and display various information. Including the following:

Reading Virtual USB device…Done.
->Serial: A35B68C9, HW: 0.0
Testing Interfaces…
->USB DKU2….Supported.
->USB CA-53…Supported.
Testing Directories…

–>Please copy the loaders first!
->DCT3 Loaders Dir(’fls1sup’)….Found.
–>0 file(s) found.
–>Please copy the loaders first!
->Products Dir(’products’)…….
Not Found

Even though it displays ‘Not Found’ on the last one, this is the Correct message.
Click the Phone Info button at the top of the screen.
Click the Read button.
As well as other information this will now show you the current product code of your phone. You now need to change this to a generic Nokia code. I personally used the ‘Euro 1 Code’ 0549487. Click here for full list of codes.
Replace the current product code with the new code.
Tick the ‘Enable’ checkbox
Click the Write button.
All done!!
You have now changed your phones product code!

If you would prefer to double check this then you can do so by clicking the Read button again, this will show your new product code (0549487).

5. All that is left to do now is install the new firmware update. Make sure your phone is connected to you computer through the USB cable and then open the Nokia Software Updater.
Follow the onscreen instructions and install the new firmware.
Do not disconnect the phone at this stage.
Once the update has finished the phone will restart

6. That’s it, you phone has now been completely debranded!
You can now restore your files by using the Backup utility.

7. From now on if you ever need to update your phone (version/firmware) all you have to do is use the Nokia Software Updater. No more code changing, this was just a one off.

I hope this is useful, and easy to follow.  If you have any feedback regarding this guide good or bad feel free to leave me a message and I will update this accordingly.

Thanks,
