Hi there, please bear with me as I am new to this. I have just bought (May/2012) an openbox s9 from Hong Kong, which isn't a clone (98F2). I attempted to imput a 24hr c line tester manually, but with no joy. A friend of mine confirmed that the c line tester worked on his same piece of equipment, therefore I think the firmware needs up grading. The version I have @ moment is: C2HS2-11-08-24:0679CMT. I am placing this post to enable for me to download the cccam.cfg from the first page to see whether this makes any improvement.
