Check imei (15 numbers) number of your phone (by *#06# in dialer) witch is shown on the box. Mainly those errors appear when phone can't identify in the network. Check your backups of the system though efs folder that contains your imei number is usually not backed up and you have to back up it manually.

The original thread was on xda-developers and I made a small review on it for you.
