Here is how.
Request OTA pairing of your subscribed card in its official box,
Log the EMM stream at the same time.
Search the log for the EMMs associated with your box.
Determine those EMMs that are used to create the INS7E payload.
Extract the info needed from those EMMs.
Make your own unique INS7E.
However, as I have already stated, this is a totally useless exercise unless you can dump the K1 pairing key from your box's CPU.
No one is sharing how to do this.
I do not know either, so please don't ask.
