Okay, I understand that there is no CA Diagnostics on the official box menu. Hence, the only way to obtain ins7e is to make the log between smartcard and official box.
If I remembered correctly, ins7e that is on the emm is only sent on the first time that the card was paired with the official box. Once the card and the official box were paired together, ins7e would not be sent via emm again. Sky De allows its subscribers to unpair the card with the official box and then pair them together again, hence we can use this to obtain ins7e via emm.
