Default S-Off but bootloaders locked, what to do?

My DNA was previously S-off and unlocked before the latest kitkat OTA, when the new OTA came out I fastboot flashed the latest HBOOT and Radio before I started using a custom sense 6 rom. It seems that with the HBOOT update, my bootloader became locked and the tempered sign is gone as well, I tried using firewater, but since my phone is S-Off the application just say there's not anything it can do and closes. What can I do to unlock my bootloader? Or do I have to return everything to S-On and run firewater?
