Default Did I...

I'm pretty sure I hard bricked my S3. I go to turn it on and all it will do is vibrate once. I can't get into download, or recovery. Before that it would get stuck at the galaxy s3 boot image, and I could get into both download and recovery. I tried factory reset and what not and well now I'm here.
