I decided to write this up, to expand on Greenleaf_420's brief debranding guide that he posted here. I felt that alot more people would be more confident in doing it, if a more detailed guide was available.
Basically, this guide will run you through the proceedure of removing the firmware restriction that is often put on Nokia contract handsets. After you have finished, you will be able to update to the latest vanilla flavoured Nokia firmware, without any ugly operator logos or backgrounds.
This will only work on handsets with user upgradable firmware. Check these sites to see if your phone is in the list.
* Nokia - Asia Pacific
* Nokia - North America
* Nokia - Latin America
* Nokia - Europe
This process will void your warranty, wave goodbye to it.
I provide this information with no guarantees. I wrote this guide based on work by other people, so it would be easier to understand for everyone, I take no credit for the actual discovery of this method. This information has been tried and tested by myself and various other people with success. I accept no responsibility for any loss direct or otherwise.
Every Nokia handset is produced with a product code. The product code is a 7 digit number begining with 05 (I.E 0536075). These 7 digits codes are made up of 4 different pieces of information.
* The Model. (N95, N76 etc.)
* The Appearance. (Black, Plum, Red etc.)
* The Language/Region it was created for. (France, UK etc.)
* The Network that customised it. (T-Mobile, Vodafone, Orange etc.)
The problem exists, that while a phone has a product code stating it is locked to a network, it will only accept that networks firmware. My N76 was locked to Vodafone, and while it had its original product code, it would only accept Vodafone firmware. What we intend to do, is change the product code, and trick the phone into thinking it is operator free and unlocked, so the Nokia Software Updater will apply which firmware you like.
As long as you chose a product code for the same model without an operator lock, it will be fine. You can use one with a different colour or location, it does not matter. I'm currently using an product code for a Red N76 from Asia, for my Black N76 from the UK.
What You Need:
Nokia Software Updater - This is an application from nokia that allows users to update the firmware on their handsets without taking it to a service center. You can grab this application from one of the locations I posted above.
Nemesis Service Suite - This is the application that will do all the tricky work. You can get hold of the latest version from here.
GSM Magic a.k.a TNT Enforcer - This is a handy little application that allows you to click on greyed out or disabled buttons in any application. For some reason this programme has become known as GSM Magic but is actually called TNT enforcer. You can grab it here.
01 - Download and Install Nemesis Service Suite
02 - When you reach the Hardware Selection Page, leave the option as it is.
03 - Connect your phone via the appropriate cable.
04 - Wait for windows to install all the necessary drivers. (Make sure Nokia PC Suite is closed)
05 - Launch Nemesis Service Suite
06 - Click the "Scan" button in the top right of the NSS window.
07 - Click the "Phone Info" button on the main toolbar.
08 - Click the "Scan" button on in the right of the new pane.
09 - Launch TNT Enforcer (Without closing NNS).
10 - Click the enable text so it turns green.
11 - Enter your chosen product code in the "Product Code" box and tick "enable"
12 - Press the "Write" button.
13 - Close NNS and TNT Enforcer.
14 - Launch Nokia Software Updater and update to your lovely new Nokia Firmware
Now, finding an appropriate product code is the hard part. It took me half an hour to find a code for my N76 that would let me update it to the new Nokia firmware. Try searching for the following terms:
* Nokia [Model] Unbranded (Nokia N95 Unbranded)
* Nokia [Model] Product Code (Nokia 6630 Product Code)
* Nokia [Model] Productcode (Nokia N91 Productcode)
* Nokia [Model] Generic (Nokia N76 Generic)
Hopefully this should turn up a few websites where people have posted product codes, or you could even make a request here, for a product code from someone with an unlocked handset.
Hope this helped.

Moved to Nokia forums, de-branding does not unlock a phone. But useful guide none-the-less
