There are NO working files for CS 4000,5000, and 6000...the old 177 and 178 file will work briefly and then freeze up...these models were discontinued over 1 year ago and no longer supported on a regular basis..rarely are working files ever released for these...its time to upgrade to a new receiver...I suggest a Sonicview 360, Conaxsat, or a Viewsat Ultra.
here's a good place to buy from.. www.southcoastfta.com
Dishnet and Bev keys, are the same for all receivers...and Files are different for all receivers..
