I'm not familiar with Sprint error messages but it sounds like your phone is not authenticating on the network, possibly because your AKEY/SSD was wiped/cleared/corrupted when you installed the ROM. You'll need to call Sprint to find out and get it fixed. This is not likely something you can fix if it is bad authentication because the switch has to update your SSD and it most likely won't do it on it's own.
