I got 0x6985 and 0x611C from my java card in different scenario.

I have a written a java applet to send APDU command to my java card. When I am sending Init_Auth command(80500000...) to the card, it returns sw=0x6985.

But when I send the same command with pyAPDUTool, I get "611C".

It's odd. Could anyone give me a tip? Why does this happen?

Re-implement applet installer or applet deletion manager on javacard

I know that the applet installer and deletion manager have been already implemented in java card. But now I want to know if it is feasible to re-implement applet installer or applet deletion manager in a new applet?
