I have Nokia 3250 (S60 operating system), Does any bidy knows how to initialize it?
Phone initialization
What do you mean by initializing? Booting is done by switching the phone on 😮
"Dial" *#7370# on the standby screen (as if you'd call someone). When asked for the security/lock code, use 12345 (unless you have changed the default).
