i want the codes for hard format 3650 & 6680

For 6680, you can press buttons ( call + * + 3 )at once but don't expect to see "formatting" displayed on your lcd just like other symbian models, it will only show nokia and blink once and then boots in normal way again. For 3650 I think there is no hard format, but if your phone is still operating, you can enter *#7370#.

for 6680 use the greenkey, *,3 and power on button code. the 3650 can´t be hard formated, use the *#7370# code on the menu.
plz search how to section, this info is posted.
