Changing the Product Code on your Nokia N97

September 26, 2009

What is a Product Code and why would I want to change it?

The Nokia N97 has hundreds of different product codes for all the different carrier types and countries around the globe. This product code is used by the Nokia Software Updater to load carrier specific firmware to your device when it becomes available. Unfortunately, some carriers prevent updates as they do not approve every firmware builds. This means that some users will not get the full benefits of the latest updates from Nokia when everyone else gets access to them, such as the recent update to Ver.12 fo the firmware.

Another reason you may want to change your Product Code, is that you want to remove all the carrier branded software and themes from your device. Changing the N97’s Product Code to a generic Australian one means you get the Nokia updates as soon as they are available for the region and it has the generic country region software installed.

Changing the Product Code

NOTE: Changing your product code uses software that can “brick” your device (render it unusable) if used incorrectly & void your warranty.

If you still want to change your Nokia N97 Product Code there are a few methods on the Internet, but some are tricky and others very dangerous as they try to install trojan horse malware on your PC. My experience with the JAF FULL PKEY EMULATOR by OGM Development, as outlined on this site, is a dangerous application that should be avoided. I tried two versions (V3 & v5) and both tried to install trojan malware over key Windows system files.

Eventually I came across The Symbian Blog’s instructions which use the Nemesis Service Suite (NSS) which was much easier and safer to use.

One key thing I came across, that was not listed in the instructions, was that you should sure you use an original device USB cable plugged directly into your PC, not through an extension cable or a USB hub. Otherwise the software may be unable to read the device.

Secondly, after the process is completed you may have to “hard reset” your device. Instructions for doing that are here with diagram.

I successfully changed my N97 Product Code from a carrier code to a generic Australian code (0576124) so I was then able to upgrade from firmware Ver.11 to Ver.12.
