Looks interesting. Maybe you missed the instructions that I found here. Sadly no firmware there for my KT or K3W.

I'm using Google Translate to translate into English and I see lots of "Brush" references. I think maybe "Brush" is a mistranslation of "Kindle"?
I would be quite interested to see how this works out.
