Just a comment for 1730dev posted by hammer in firmwares section.
This firm developped by ptileray for ts7 dont work for tps and for nagra coz the function send_ecm nagra 2 is incomplete,you need to implement this function with defiant:
Po_func_call_28A(dum p.CAID_HDL, dump.SOID_HDL, dump.Addr);
every time before flashing to keep nagra 2 (kudelski)working
ps:don't work for premiere MECM too
