Welcome to Android Central! What do you mean by updating software without an internet connection using a secret code? Are you talking about a system update or app updates? If you didn't have an internet connection, were you trying to manually install a system update file that you had downloaded from the web somewhere? If so, are you certain that update was for your specific phone? Installing the wrong update to a phone can make it inoperable.
