Default code is 12345. If you changed it but cant remember what it is then you can get it reset at your local care point. You will need to bring proof of purchase with you. locate your nerest care point using the link below.
If you forgot the security code/lock code of your device the only option for you is to take your phone to Nokia Care Point and they will reflash it, after that security code/lock code will reset back to default.
Note: All files that you have on the phone will be deleted once they reflashd the handset.
can that restore the security code?
Use of said software applications have no bearing upon implementation of device lock code.
If I've helped in any way, a click upon the white kudos star would always be appreciated.
