I've been using 6.0 0002 on I9300 just fine for over a week, and suddenly today it has no connection, no bars. Under Settings > Cellular networks > Preferred network type, it says: "Invalid Network Mode (-1)"
Everything on that settings page is greyed out. I've tried reinstalling 6.0 0002 and 6.0 0001 and still get the same error.
An internet search revealed other users with the same problem, one of which was fixed for a different device by flashing a modem.bin:
