How do you unlock Nokia phone?

Answer 1

Update your phone's firmware using NSU (Nokia Software Update).

NSU reads the product code of your phone and it searches its database for a newer version of the corresponding firmware in order to upgrade it. This is why you will need to change the product code of your phone into a non-branded product code, before running NSU.

See related links to download the « NSS » software in order to change the phone's product code and the NSU.

1. Install NSS
2. Install NSU
3. Connect your phone and wait for Windows to install the drivers
4. Open NSS and click on "Scan for new device" on the right-upper part of the window
5. Click on the icon « Phone info »
6. Click on "Scan"
7. 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".
8. Now press "Write", and your phone's product code will be changed.
9. Close NSS and you can proceed now with the NSU flashing.
10. After flashing with NSU, 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!

Ps: Disable any antivirus and firewall on your PC during the flashing.
