Kindle Keyboard connect by WiFi to isolated AP

[hfpop]

I am interested in the following scenario:

Kindle Keyboard connecting by WiFi to a mobile phone WiFi access point. The phone itself has no connection to the Internet. Once the connection is allowed and done, we run the KK browser to access the mobile phone directory structure and sideload books from it.

Current problems:
(1) KK does not allow connection to an AP not connected to Internet. How to circumvent this restriction?

(2) When problem (1) is solved, it may be the case that the browser itself does not run for the same reason as before.

Does anyone have a solution to these problems?
As well, do these apply to Kindle PaperWhite?

Thanks for any input.
