I always liked bricked LLLs, but this one is a hard one.

I don't really know any other things you could do at the moment. I'm going to read through some pages in the EPC700-Web directory on Ard's website.
After a lot of burned fingers I finally got my LLL working again. I've put it in an old Digital Picture Frame with a broken screen. Works really well. The only thing I hate is that I have to use an external mouse and keyboard to use it.
@wicknix: I changed the 3MX page on Wikipedia a little bit. Most of the information was quite old or incomplete.
