Hi guys, I'm looking for Kaon 570 ksc firmware, I really searched inside forums but I'm a little in trouble, since I found a lot of firmware related to the Kaon 570z ksc or 570h ksc, what's the difference ? which one I really need? should I flash my receiver with a firmware of a kaon 511? I don't know anymore, please help me. This is the spec of my receiver: Model: KSC-570 Info: 20.05.20-D1AA S/W:V13.05.04 H/W:V12.C1.A5 Loader:V6.1.9 C.A.:2.2.3 any help will be appreciated. Thanks -
