I have no idea on how to add support for those files, also I have not modified any files.
After getting a black web page I extracted the cgz and jgz files but I don’t know what to name them, when I extracted them it showed just a bigger file with no extension, I tried renaming changing only the extension but there is already a file with that name app and jqm, I am really lost with this new way of changing the ui it used to be way easier when loading from sd card.
