Heres' a tutorial that will teach you how to update your phones

firmware to a Nokia original version (without your operators personalization) with NSU

(Nokia Software Update the official Nokia program).

NSU reads the product code of your phone and it searches its database
for a newer version of the corresponding firmware in order to upgrade

This is why you will need to change the product code of your phone into a non-branded product code, before running NSU.

Download the NSS software in order to change the phones product code.


And finally, download NSU here:



Install NSS

Install NSU

Connect your phone and wait for Windows to install the drivers.

Open NSS and click on Scan for new device on the right-upper part of the window

Click on the icon Phone info

Click on Scan

As you can see, now you can change the product code (on the right of the phone info

window of NSS). For a Nokia 6680, type the product code 0521637 (this
is the product code for France!) and then mark the case Enable.

Now press Write, and your phones 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 dont worry, the product code changed !).

Close NSS and you can proceed now with the NSU flashing.

When the flashing with NSU is over, start-up your phone and you'll have
the pleasant surprise that your phone's firmware is the latest Nokia
non-branded firmware in date!

NOTE: I advise you to disable any antivirus and firewall on your PC during the flashing.
