The zip is password protected, so that you are not allowed to extract files. But you are allowed to add and replace files. And maybe even delete files. Booxtor himself pointed out this possibility to modify firmware before instalation, long time ago.

EDIT. I like the surrealist map. To me it expresses, we should focus on the ocean, it is the main feature of the Earth, not the land.
