[Magisk] rfgamaral:
Here's the full module: https://drive.google.com/file/d/0BxKzMVB35Z6RZ2VldEF0eUxRQWM/view?usp=sharing

Here's the log with debug enabled (feels too small but the option is enabled):

But there's definitely something wrong, look at this:

For some reason, it seems to stop copying files... module.prop is also 0bytes and on Magisk Manager, the module shows as installed but the info is all wrong:

As I said, if I add a single file to each of the 3 folders, all of them are copied, module.prop won't be 0 bytes and everything will work just fine.

Not sure what am I doing wrong.
