I seriously doubt we are going to unlock the bootloader, it just doesn't seek worth it on this particular device because we have 3 or 4 other model kindles already available to flash and they technically have better features on them like HDMI and a camera, so I would think someone would be more intersected in the HDX's if anything, and who knows an exploit on them might work with the bootloader on the 2013, but no guarantees on that as the CPU and hardware is different so I'm assuming the bootloader quite different.
As to your problem with rooting, give me some feedback or a log of the terminal output so I have an idea of what happened, I don't have a 2013 model so I have never attempted its rooting process, but I can probably help with errors. Oh and for the record, on a command print you can right click in the window, hit mark, highlight as much of the text as you want, hit enter and it copies it to the clipboard so you can paste it into code brackets here. Most people don't see. To know this for some reason and just screenshot the command prompt... Seems kinda basic that any windows app has basic copy and paste functionality in it. Lemme end this post before I start ranting about how Linux has even better copy and paste support.
