Hello,
let's assume I have a super-secure Android phone that's known for not being rootable. Let's also assume, I've successfully tried the Janus vulnerability and was able to replace the classes.dex of a system app with a slightly modified one.
As far as I understand it, using the Janus vulnerability, you can only replace the classes.dex but no resources. So whatever is in the classes.dex can only work with the resources already there.
Now the big question: Is there any classes.dex that doesn't depend on specific resources and that I could use to get e.g. a root shell?
