That my friend is a fatal file system error. The only way you will get around that error is to reinstall the Blackberry 10 OS (operating system). If that doesn't work you'll need to take it back to your place of purchase.

You corrupted the file system by removing the battery while it was resetting. Only the manufacturer can restore the boot partition.
