Update/install is simple:
http://dl.dbank.com/c0ns2ckv5w (rar archive) extract this
> 1 folder inside (duokan)
> inside this (dk_system) -> root of your kindle, replacing old files with newer versions
I realize that there is another folder (duokan\DK_System\DK_Update), do not worry about this, the install script takes care of it and copies over your device specific files (k2/k3/dx/dxg), you'll need the whole dk_system folder, and not just the one in the dk_update folder. If that is what you were talking about.
that's all you need to do for an update, reboot your kindle and update will complete.
For a new install, you will need to go into 升级包, select the bin file that corresponds to your model, and place that in the root directory of your kindle, along with the 3 other DK_ folders and go to settings, update kindle, but this is only if you have never installed it before.
Anyways, still not able to register on their forums. Still no word for an uninstall. Does anyone know if this will conflict with future AZ updates? I assume that when trouble arises a workaround will be made at that point, but still =X
