Hi Nazir,
Do you have the application note “AN1826 – MIFARE SAM AV2 – For MIFARE DESFire EV1”? In non-X mode you have to route all card commands to the SAM. With the “80 0A…” sequence you send the first card response form the DESFire to the SAM. The answer from SAM must be re-routed back to the card. The application note has a lot of examples with calculated values for en/decryption.
