3 Ways to reset your C: Phone Memory

1.Soft Format -you just have to press *#7370# and press Dial. The phone will request the security code that is by default 12345. Please be aware that you will loose all the data in your phone, so you should backup all relevant information.

2.Reset your Nokia C6-00 original settings - you need to press *#7780# and then Dial. The security code is 12345. Once you complete this, your phone will come back to factory settings, but you will not loose personal data. Anyway it is recommended to make a backup before performing any of the mentioned procedures. 

3.Call+END+Camera keys together -during a power on performs a hard format : this will return the phone like you have received; make sure to have full battery charged !
