Honestly, the best way to get a supermax-sm-2350 or any other decoder de-scrambled is to speak to someone that works at a TV/Cable repair shop.
I know it's not exactly the information you might want to hear, but it is genuinely the best advice. You'll read a lot of BS on the internet about descrambler boxes etc... At the end of the day they are just trying to sell you some hardware which may or may not work.
This is the real info you need to know:
In order to descramble premium channels on your Supermax decoder, you're best of taking it to a repair shop and speaking to a pro.
Pick a store that "looks the part", and casually start a conversation with the individual working there about the prospect of unlocking super stations that show premium movies and sports.
The reason I recommend speaking with a professional is that, not only is technical knowledge involved, but you'll also need to purchase some very specific hardware, which a retailer would easily be able to pick up from a supplier or wholesaler.
Basically, it'll save you a whole lot of time.
However, when approaching a TV repair guy about the possibility of unlocking some extra channels on your Supermax SM 2350, make sure you are discreet and polite.
Hacking decoders comes with a $500,000 fine or a maximum sentence of 5 years jail time, so anyone that is willing to perform this hack for you will be putting themselves on the line by trusting you.
