But when i tried to install KPVBooklet, the .bin file is deleted and the "Update Your Kindle" link stays grayed out.
so what should i do?
Is this kind of kindle's mechanism that it delete the .bin files copied in its root dir?
The packages on NiLuJe's snapshot thread are re-packaged for device 9017 - use those packages.
Yes, it is a safety protection from installing a .bin file not intended for that model.
Packages are both "model locked" and "digitally signed" -
Mis-match of model or bad signature - update file gets discarded.
