Cannot list or install CAP files in JavaCard after unlocking. Why? and how to solve it?

I have a SmartCafe JavaCard. I was able to unlock it, but I cannot run any more command on it. What else can I try?

Maybe it is because the protocol? But I didn't found a way to change the protocol. Do you have any other idea

The mutual authentication succeeds:

A>> T=1 (4+0016) 84820100 10 BA9CC3E1E77BF3634913ED6DF33F8FEA A<< (0000+2) (46ms) 9000 ~~

But the GET STATUS command fails:

84F28002 0A 4F0056F974428777BDCE 00 A<< (0000+2) (49ms) 6A86 A>> T=1 (4+0010) 84F28000 0A 4F006C54999C15CDD096 00 A<< (0011+2) (52ms) 08A000000003000000079E 9000

The first GET STATUS command searches for the Issuer Security Domain in the new format, but receives "Incorrect parameters P1,P2" as response.

The second command tries to read the same, but in the old format. Here a response is received but gp seems to have parsing errors for the result 08A000000003000000079E.

The parsed result should be :

08 - length A000000003000000 - AID 07 - life cycle state = card is initialized 9E - application privileges

Please raise an issue for the gp tool. It should be easy to fix it.

Can you try to use an alternative tool for your task while this issue is not fixed? I'm the author of GPShell and based on the code base I would assume at least this error should not occur.
