Hi,
Your Card is JavaCard.
Gpshell can be used to manage the javacard applet. you can try it.
Also if gemalto
could give the applet cap file, you can use it to install again.
I'm afraid, GPShell will not not work. Because it might be impossible.
definitively ! when the card domain is in terminated state, it's in
terminated state...
Actually I see no reason why a card could not be rest to the default key
set and empty state. If all data is zeroed out, nothing should happen. But
maybe there a some security problems I do not see. or the manufacturer
wants to earn more money.
?!? and what is a default ket-set ??????
you really want a GP card to reset all its internal protection to a dummy
000...000 key when one try to attack it ?
you really want your credit card to reset its PIN to '0000' after 3 invalid
verif. attempts ?
humm, hopefully nobody introduces such "feature" in the spec.
btw, if you're using a test card (and I can not imagine that we did manage
a key ceremony with Axalto) the keys are likely to be 7071...7F, 6061..6F,
8081..8F and are very likely present in the first pages of your user guide
(or dev. datasheet); normal use will so never lock the Card Domain.
regarding velocity checking, a try counter is present since GP 2.2 (some
months, years...), with OP 2.0.1 we use to only introduce a growing delay
after each Initialize Update issuance but no try counter.

Thanks for your reply!
It is a new card. I have not loaded a applet to the card!
So there is not an instance and pin in the card.
The application selected is Card Manage (A000000003000000).
I send InitializeUpdate APDU command three times without following
ExternalAuthenticate APDU .
"If you send an InitializeUpdate APDU command three times
without following the command with a successful
ExternalAuthenticate APDU, you will lock the key set."

The gemalto's reply is that there is no way to unlock the key set. The
card has became invaild.
Thanks

Hello,
Please try this command
B0 46 N 00 L *******
N is your pin code reference L is the length of unblock pin
***** is unblock pin
BTW, why did not you try to delete and reinstall the applet?.

Are there some methods or commands (APDU) to unlock the card?
