I am trying to reprogram my Virgin Mobile SE47. I have entered the 111111 code and gotten to the menu. I have selected Programing and have cracked that code with 847446 (V-I-R-G-I-N) and I get to the next screen with the ESN, NAM MIN, etc. but I can't change them. I am trying to reprogram the phone to work on a different network.

Now, I am having a problem with the Programing code. I cant get in using the 847446 code which was working earlier.
