I had the same problem yesterday,but no luck since then!
When CAS3+ load the file Underworld 2.22 for me,it displayed it as a file for all diablo cams and not for Wi-Fi only.
I sent an e-mail in their official site asking for help
Waiting for their answer.
Please do the same so they know it's not only me.
Meanwhile have a look here : http://www.satsupreme.com/showthread...ations-problem
where no solution found
and here :
where the guy "humax5400z" found a solution,
but notice that his cam did not start the update at all on the first failure.
Our problem is that the update was interrupted and the cam can not get initialized by any receiver or programmer.
Might be there any "forced OS reset" method for Diablo CAMs out there?
Who knows,don't forget to e-mail them for your problem,please!
P.S. Here's one more discussion about the same problem
