Unable to delete applets or packages from cards

[Laura-IsANoun]

I'm struggling to delete apps from an ACOSJ card.

I use the gp --delete XX XX XX XX XX command

then get this message:
'Could not delete AID: XX XX XX XX XX
DELETE failed: 0x6F00'

Why could this be? I'm running the latest version of Global Platform Pro

[martinpaljak]

As always, do provide a log as instructed (also the contents of the card before deletion).

This (seems like/is) a generic exception from the card, so hard to say why.

[Laura-IsANoun]

Contents of card before deletion and log:

[martinpaljak]

Please paste text not screenshots.

What if you try to delete the package, not the applet? that is gp -delete 0703199600 -f -dv

[Laura-IsANoun]

Sorry!

If I try to delete the package I get this:

You need to ask your card vendor why the delete is failing. A buggy card maybe?

[Laura-IsANoun]

I will do - thank you. It did work before so I am wondering if perhaps it's something within my apps code
