Take the battery and SIM card out for a few minutes and try again.Otherwise, re-run the update service.
i already follow waht u say..but it still not working...
Try another SIM card and if that doesn't work, perform a master reset on the phone.
i already try it both..but still not working...
Then contact SE.
Restore to factory/default settings.
