unlock the ISD

I know that each transition from state to state is irreversible except from CARD_ LOCKED to SECURED, only to the ISD.
That is, the Card Life Cycle state transition from SECURED to CARD_LOCKED is reversible.
I tried to LOCK the ISD with the following APDU:
>> 80 F0 80 7F 07 A0 00 00 01 51 00 00
The command was successful but I can not login to the ISD any more. How do I unlock the ISD?

Your card probably enforces secure channel security level C_MAC once the card life cycle reaches the SECURED state.

Continue to send command to select ISD and establish secure channel. Then change card life cycle back to SECURED.
