Broken J3H145

[ckahlo]

Hi there,

right now I managed to break the second J3H145. The first one was a "FIDESMO Card 2.0"
RFID-only featuring the J3H145C7A6. The second one was a "J3H145" from JavaCardOS store.

The 2nd card responds with the ATR 3B 9E 95 81 01 41 4A 43 4F 53 01 45 48 54 01 52 01 56 00 83
with "AJCOS EHT R V " in the historical bytes.

After uninstalling an applet because the install of another applet failed (i thought of problems
due to lack of remaining space) the card ran into a timeout. After that it didn't respond at all
and I got "unresponsive card" for a while. I gave it power and a clock signal for a couple of time
to let the transactional memory management run through and now it responds with an ATR again.
But it is impossible to send a command to the card.

Did someone else already expierence such problems with J3H145? Is there a known way to revive
the cards to get them back into a working state? Or are they simply dead now?

Best regards,
Christian
