Updating n95 8gb
Note that by proceeding with the upgrade in the manner described hereafter you will void the warranty on your handset and you may lose some operator-specific functions. One method they have of protecting them is by installing customized firmware into the phones that they provide to their subscribers.
Firmware is the software embedded in the handset that defines things like the phone's menus and other things like pre-defined media (images, music clips, videos etc.), and basically makes the phone "work".
Second from the left in the second row of icons in that window is "phone info".
Click on it and you'll get something like this: Towards the right there's a section in the window called "Production Data Edit".
The whole procedure will take about 10 minutes plus the download time (a few minutes on a fast broadband connection). You now have an unbranded N95 with all the bells and whistles of the original software and without all the advertising and restrictions imposed by your network operator. Then choose to restore a previously made backup and select the backup file you made just now.
The author of this document cannot be held responsible for damages caused to your phone in the event that the procedure fails and you're left with a "brick".
This procedure worked flawlessly with the handsets I've upgraded but in no way can I guarantee that anyone else will have the same success rate. The idea behind this is to change the product code of your handset in order to obtain newer software for it. Mobile network operators are extremely protective of their revenue streams.
Enter this code into the "Product code:" text area above, check the "Enable" checkbox just to the right of it (and only that checkbox) and finally click on the "Write" button.
There will be no visible effect but the new product code will be written to the phone.
Click on the "Read" button at the bottom of this section and information about the phone will be filled in (note that this confirms the product code printed in the battery compartment): Next go to this page, where you will find the product code for the vanilla version of the N95 in your region.
