A while ago I really needed to debrand my N95 so that I could install the latest firmware update at the time (v.20.0.15) and therefore be able to use the sensor module that came with Python for Series 60 v.1.4.2. In the past I had read a couple of posts in various forms and I had really been scared away from attempting such a thing, because “…you can break your phone and never have it work again”. Anyway, as I really needed to do this to be able to write applications using the sensor module I took the courage 🙂 to actually go for it. As it turned out it was much simpler and less dangerous than most people presented it to be. A nice guide I found and followed was this. For the sake of completeness and because I can never be sure that this resource will be always available I have copied the steps below.
Note that the real dangerous thing is while updating the firmware on your phone, during which you should at not time interrupt the process. As this is a procedure you normally get into anyway when you want to update your firmware, debranding the phone per se does not put any higher risk on your phone. Just be carefull when updating the software and you’ll be fine.
You can find your phone’s current firmware version by typing *#0000# on your phone. To check if there is an update for your phone go to the Nokia Device Software Update page.
Debranding your phone
First of all you need to get the Nemesis Service Suite and the Nokia Software Updater.
- Connect your phone and wait for Windows to install the drivers.
- Open Nemesis Service Suite and click “Scan for new device” on the right-upper part of the window
- Click on the icon “Phone info”
- Click on “Scan”
- Change the product code to the one you want from the list below.
- Mark the case “Enable”.
- Press “Write”, and your phone’s product code will be changed (you might think that nothing happened, because the phone is still in normal mode, and the changing of the product code only takes a couple of seconds, but don’t worry, the product code changed !).
- Close Nemesis Service Suite and run the Nokia Software Update.
- Make sure not to touch the cable or the phone while your phone is updating or else you will break it!
- That’s it! When you restart your phone, it should now be upgraded!
