Tip 2 : Shit happens, on a smartphone, its inevitable u do something wrong, and this calls for a format of fone. to format the fone, press *#7370#, then enter the lock code, which is the sec code of the fone. NOTE : batt must b full, else if format is disrupted by low batt, consequences will b disatrous I heard the code *#7780# works too, pretty much the same i tink.
for 6600 users, to format the fone, theres an alternative way. Press and hold <3>, <*>, and the buttons, then power on fone, keep holding on the 3 buttons, till u come to a format screen. tis method ONLY works on 6600, and need not enter the sec code. BUT sec code wun be reset to default 12345.
There are two kinds of formatting: hard formatting and soft formatting HARD formatting: This reformats completely the C-drive. All applications and files stored on this drive will be lost and clean but default files will be rewritten. This is a deep reset.
HOW? Again there are two ways:
1) *#7370#
2) When unable to startup your phone: press and hold the green (talk) key on the left + number 3 on the keypad + the * key and then turn the phone on. This trick works on every S60 v7.0 and it works fine on my 6630 too but without formatting screen...
