I picked up a 6000 premium on Ebay. I am trying to setup 91w on it with my bandstacked lnb. The OCS setting in the menu shows 2 lnb frequencies on it. But when I try it it doesn't work right. Doesn't switch back and forth like it should. I am not sure if it is a firmware issue or if the box just doesn't work for bandstacked lnb. I think it has pirateware in it but I am not sure how to load good firmware. Has anyone here successfully used a bandstacked cband lnb with this receiver?
