i have never used a blocker image but was just wandering if they were any good do they still auto update or not what are the pros and cons of these images???
pros - a blocker will block the current emm.
cons - it would be very easy for the cc to get past it and kill your card.
Much better just to make a realistic image using my tut in below thread as this will ensure your card is as close to a real subbed card as possible and so very difficult to target by the cable companies.
You could do this but if you use a realistic image and keep it up to date then there is no need for a blocker. However there is nothing wrong with doing it.
