Would you be able to put up a copy of the /app/ directory with this utility? I have only seen one kindle, a PW3 on 5.12.4 with an /app/ directory. It does not have the junoPortal or a tools subdir, but it has a number of other interesting binaries and libraries.
/app/bin/screenControl opens a web server on the kindle which serves an interactive screen, and optionally inspects the elements rendered on the kindle's display, similar to developer view on a web browser.
Attached is a copy of the /app directory from that kindle.
Thanks
