In that case I wonder if he has switched methods for FeC activation, surely someone else here would have mentioned that.
It sounded like he was purchasing legitimate FeCs for you and activating them via ODIS/FaZiT? Perhaps now is using the known hacking method of dumping FeCcontainer via root shell, generating new fecs, and patching your MIBroot to ignore fec checking. If thats the case, hopefully he is charging less.
Do you have more information about this? I would love to learn how to do this as I have not had carplay activated yet on my system
