Bootlooping, Recovery Corrupted, Cant enable USB Debugging am I screwed?

After messing around with my shield last night and not being able to get root access on cm12. I tried to reinstall one of the ota updates from a while back. Now I am bootlooping and when I try to boot into CWM it looks to be corrupted and doesn't load. I cant use ADB because usb debugging is no longer active. Does anybody have any suggestions to re-install recovery or somehow enable debugging or am I dead in the water here? Any help would be greatly appreciated
