I had the same exact issue.  Also, I couldn't send, receive or view old messages.
What I had to do was power it up without the SIM card.  You should get a message that there is no SIM card - that's ok.  Then power it down, re-install the SIM card and power back up.  My problem went away.

remove sim when it says insert sim try this code
