Thanks a lot for your help.

Now, I reached to this step:

8. open rooted Filebox (password: rootme) and move that .zip to /opt/waxmppplugin/bin/wazapp folder

But I don't know where to put the password in order to have the permission to move the .zip to wazapp folder

The file box settings can enable the show root filesystem without password, but I can't move or copy any files on it.

Can any one help me please ?
