X6 bricked after loading wrong recovery.img

I have spent 2 evenings reading up on custom firmwares and there isn't much information about this board yet. My goal is to use it as a thin client, preferably by booting Gentoo, Arch or Ubuntu on it. There is the ODroid C1 from HARDKERNEL which makes it's source code freely available, so if their tools are compatible things look promising. I've also found some threads about people with various levels of success booting Arch on other S805 platforms.

I found that I can boot into recovery mode...
