Come on, guys, I want the next post in this thread to be: "I tried it and it worked!"
--Edit
I gave it some thought and it's starting to dawn on me, that this probably can't be done.
I think it's the same as with bookeen's updates, it's not the complete image and on top of that there seems to be some testing done during the installation whether it's the right kind of device.
Well, that just makes me sad, because for a while I really believed that this magnificent firmware could be used on cybooks too.
