First...of course you "bricked" it, the Logik Dax has a completely different hardware inside. What did you think you would accomplish by doing that?
Second...in usb boot mode, it I don't think it will show up as a drive, nor do you need a driver. You need to use tcctool to upload the proper firmware to it. tcctool may need to be modified, I don't know if it supports the x20. Ask linuxstb in irc, he wrote it.
Third...post a larger hi res picture, I can't make out anything on that one.
