help with oscam please!!!!!

Hi Guys, trying to get oscam working on my sab hd android receiver. I was told it had the exact same firmware as the amiko a3. I can't for the life of me get oscam to work, I've tried everything and just can't work it out. I don't need a separate card too do I? It's an n line I have. Any help pleeeasse would be greatly appreciated!! Hammer at the ready if not!! Thanks in advance...
