How To Format Nokia Series 60

On a Series 60 v1 based phone (N-Gage, 3650, 7650)

Steps
Normal Reset (*#7780#) : Restores ini files from rom but preserves user data (photos, 3rd party apps etc)

Deep Reset (*#7370#) : This reformats completely the C: drive. All applications and files stored on this drive will be lost and clean default files will be rewritten.

In both case, the phone will ask you a confirmation and you will have to enter a security code (12345 by default).

On newer Series 60 phones (6600/6620/7610), the sequence is slightly different:

Steps
Turn your device off.
Press (3 + * + CallButton) Together.
Turn your device on while you are pressing the three buttons.
You should now see “Formatting ..” on the Screen! Leave the buttons now.
Warnings
Don’t apply these steps if you are not sure what you are doing.
Make sure you have enough battery power before beginning this procedure.
Formatting will erase all your contacts/messages, so make a backup of your phone before formatting.
