If your seeing korean writing, it is probably an error (im not 100% sure, i dont read korean) if you try switching it off and on a few times, you should be able to see a list f files on the card.
you might want to try an earlier version of the software,
from here one of those might give you better results.
If you have a look around the forum, you might notice that some r6 card dont work with the latest software, the neoflash team are aware of this and will sort out that particular problem once the software is a little further in development. Hopefully you got the latest version of the card (im not sure how to tell) and everything should be fine.
