Some progress on the PW1...
In this 5.6.1.1 firmware search_bar.js is one monstrous line and changing the consts does have some effect:
The kual button to "replace store button" sets:
Code:
const F="file:///mnt/us/documents/KUAL-KDK-2.0.azw2";
and nothing happens.
If I change F to aK, the search bar at the top disappears altogether:
Code:
const aK="file:///mnt/us/documents/KUAL-KDK-2.0.azw2";
(I found aK="store" by searching the long line and figured it would probably do something.) Gotta copy this search_bar.js to PC and study it a bit after wrapping the lines.... Such fun!
