Good ideia Shahid! . I'm actually trying to find more info also right now on the Cerebro cards, as I have confirmation also that they are opening the Premi*re channels, even on official Premi*re receivers(Humax PRHD-1000!). The files are usually named "383c" or "384cz" and in hex. format. Some give the feedback that the right file dependes on what type of receiver suites best( ?). For the T-Rex 3.43 w/ Cerebro card, the most used file is the 384cz.
