K810 password protection

[LmAn`]

I need a little help here :
i dont wanna block my contacts and calls, i only want the file manager and the messages to be blocked. Is there a way around.
i dont want password on the keylock. should i leave the 12 '?' as it is. will that work ?

1.Go to Settings-> General-> Locks-> Security phone-> Security-> Privacy and check only "File Manager" and "Messaging"

2.Put ";" before the line

117e294: 313132003931 ????????????;Password is set here for unblocking keyboard "only"

and you won't have pass on the keylock.
