There are multiple reasons for getting status word 6985 on delete command. The common ones are listed below.

1. The package you are trying to delete is used by another applet, therefore JCRE will not allow deletion of this package in the first place.
2. The applet you are going to delete is having some reference of static array in it. De-referencing the array on deletion is necessary, otherwise it cannot be deleted.
3. It is a system pack and cannot be deleted.

please explain what is [Wrapped CMD] here

This delete command is send with a secure messaging wrapper (CLA: 84h), hence it is having MAC attached (last 8 bytes) to it. Because this MAC is wrongly calculated, so you are receiving 6982. Check K_MAC for this.

There is no need for secure messaging command to delete the package/applet. so check above 3 conditions in you applet.
