If you lost all programming the system would still work, so that is not your problem. On default (lost programming), you would still be able to receive and make calls.
It sounds to me you have one of two problems. Either a main board failure, or the program has been corrupted.
First course of action is to power down the system, wait 60 seconds, then power up.
If that does not work, default the system.
If that does not work you have a hardware failure and I would need a tad more info to get you through that.
