Reset Security Lock by Service Box

Sometimes you cannot access your Nokia phone because you have forgotten your security password. It happens frequently that we change the default security code of our phone and then forget the new code.  

Factory Reset your device

In some Nokia’s devices there is no way to perform the hard reset without inputting the security code.  What is worse,  sometimes  because of the lack of the USB port it is impossible to upload a new firmware by performing the flash operation on your cell phone. That way you can not restore the default password or restore the old one. As a result of this you can not fully use your phone or perform a factory reset.


In this sort of situation the only way to reset forgotten system lock code can be done only by professional service centers. The companies providing this kind of service are able to reset your security lock to default one by using GSM Box and FBUS Cable.
