So I've just jailbroken my Kindle Paperwhite 3 with that newly released jailbreak method and I can't install this hack. (I've been trying the Python thingy only; if I don't get the Python to work then I won't even try the hack itself since it won't do what I want it to).
I download the correct file but the "update your Kindle" doesn't turn black.
When I plug my Kindle back into my computer, the installation file is mysteriously gone.
My Kindle Paperwhite 3 is running 5.6.5 (Brazilian Portuguese), serial number starting with G090 G105 (dunno if it's relevant).
If you need any other piece of info just lemme know.
Thanks!

I've tried restarting it and going through the process again but no luck.
