Sorry to ask again so quickly, but this is becoming quite an urgent issue
for me.  During my search I found nothing on how to determine if a card 
is
in fact locked.  According to the global platform spec, a locked card 
state
is there to disable "security domain and applications functionality"  and
yet I can select an applet and a security domain with no problems, and 
even
send and receive data from the applet.
The privileges by the various classes subjects to assert the right to 
perform given operations -  in given states - is shown p105. See column 
locked/ISD. Select is authorized by an issue, when the card is in LOCKED 
state.

But init-update gives me 69 82, followed by 69 85 for EXT-AUTH if I try 
to
do it anyway.

More importantly, the GP spec doesn't say how to reverse from LOCKED to
SECURED.
Presumably, authenticate as issuer to the ISD proxy on the card, then 
perform set-status.
p 136 to track back one state transition.


Could anyone point me to a resource or give me a hint as to how to 
resolve
this situation?
Use get-status, obviously, to learn the current card state.
Regards,
Mladen

Hello all,
I have a JCOP21sim card that worked fine in the past, but no longer lets
me
authenticate.
If I send it INIT-UPDATE, I get back "69 82", which makes me think that
the
card is locked.  However, I can still SELECT my applet and run it (send
data
to it and I get data back).  Also, I read in the Global Platform spec I
read
that the CARD_LOCKED state is reversible.
So, does anyone know how can I find out if the card is indeed locked? 
And
if it is, how can I reverse the state to SECURED?

Any help would be much appreciated,
Mladen
