That's probably way. The rooting program evidently corrupted your recovery and download partitions. Unfortunately, if you can't get into download, you can't fix it that way, and it's cheaper to replace the phone with a newer (and better) one than to have someone JTAG a system to it.

Next time, don't try to root the phone. Root probably isn't going to give you anything you actually need.
