How to reset the security code of my Nokia 5200, i've changed the default code & i've forgotten the new security code.I've try few suggestions including master reset code calculator but it couldn't solve my problem because Nokia 5200 not in their list.
Can't be done without the right device on the BB5 Nokias as the security is different buddy.
You need to pop it into a phone shop to reset it if it's not 12345, that's the only way for sure as I work with phones & master codes are a load of rubbish for most.
