Default Firewater S-off wont work?

I got my One M8 yesterday from an upgrade and rooted it, after I had rooted it I tried to S-Off with the Firewater exploit. However when I tried I get this error.

********** whelp, this sucks, firewater can not work on your device **********
********** no amount of reflashing, retrying, or ruuing will fix... **********
********** DO NOT COME TO IRC ASKING FOR UPDATES OR ETAS!!!!!! **********
********** if we are able to fix this issue, it will be announced **********
********** bye bye.....sorry it didn't work out. **********

Is there any other option to try or do I have to wait for a new exploit?
