How to format a N77 beacuse i forgot my security code

There are two types of formats one is the soft format and the other is the hard format. The soft format restores your phone to factory settings, all data is not erased in this type of format. The hard format erases the whole data. There are two codes to perform the two formats respectively: for soft format *#7780# and for hard format *#7370# after typing both the codes you need to give the security code but you dont remember, so there's one more way to format your phone: switch off your phone. Hold*,3,green(calling)key and switch ON/OFF button together. The formatting progress will be displayed. Remove your hand from the keys after the format is completed... Rate my answer..
