In nodded app (v2) there are somewhere four dotsWell, no luck for me
I have renamed the original apk and copy the file you gave to the system folder. Gave 644 permissions and deleted the data folder as indicated. Reboot unit but widget doesn't update and the app either. The app seems the same and I can't find any settings to change the source.
Don't know if I'm missing something...

Also important: not sure if it requires Xposed... I think don't but please check with others.
