This basically means you have corrupted the EFS partition of your phone. This can only be fixed in two ways:
1. Like @johntheredimid
mentioned, you need to restore the backup (if you took a backup) of your EFS partition before it was corrupted. The method for restore can be found here - http://forum.xda-developers.com/show....php?t=2420902
2. If you didn't take a backup, you need to take your phone to a service center and ask them to fix it for you. Would probably have to have your board replaced. So you should install your country's firmware and unroot properly before taking it there. Unrooting methods can be found in the general section.
