JavaCard OS

I have a java card. And I know that there are two applets in my card. It is in prepersonalization mode, and documentation I have said that I need to personalize it in order to use the applet.
I met an error (secure status not satisfied)when doing INIT update. The problem is because I didn't create Security channel. But how to create secure channel, could anyone tell me?

Give us your APDU commands and Responses please.
INITIALIZE UPDATE command is command to establish secure channel. This command didn't need secure channel established already.
