Open up "Xposed Installer" then select "Clean Up".
Open Xposed Installer again and then select "Install/Update".
Now reboot again.

Now reboot once more.
Done, now you can use your Xposed Modules
Sorry I won't be providing single zips, but XDA has lots of talented developers which would provide you with what you need. So, simply search for it.
Sorry Again I won't be able to provide that. Basically different devices have different files which my MOD overwrites. So in order to create removable zip I must Download each devices's system dump, which is technical impractical. This is the reason why I'm telling you that it is important to take a backup.
Go ahead. Just let me know once done.
This MOD automatically configures Beats Audio for your device, you don't need to enable it as it will always be up and running.
It is not necessary that a module will work on our device. Most of the times it doesn't work because your device's hardware won't support Sony or HTC's exclusive modules as it would rely on the hardware too.
