I'm having the same issue. Got a brand new OBi200 from Amazon. The echo test works just fine. When I put in the **5XXXX code, it says, the "code as been sent to the server", but nothing ever happens. I did this a few minutes ago and during the timeout countdown, I entered the code about 12 times, got the same reply every time, but the device never go added. If I've just wasted my money on this device, everyone needs to be warned. Based on what I'm reading on this forum, this device is a SCAM, unless someone can convince me otherwise.
