To install V4A, you must have a rooted phone. If you haven’t rooted yet, you can check for your device in our Rooting section.
Make sure no other audio mods are installed, like AudioFX. If there is, you will need to remove it completely. You must have BusyBox installed on your ROM.
In case the driver installation fails – It seems like some manufacturer specific devices require SELinux status to be set as Permissive. You can use SELinuxModeChanger app to do the required.
Steps To Install ViPER4Android On Marshmallow:
Go to the V4A website and download ViPER4Android FX: Link | Direct link
Move the downloaded ViPER4Android_FX_v2505_A4.x-A7.x.apk to the phone’s storage.
Make sure, you have enabled Unknown sources in Settings > Security.
Now, using a file manager (e.g ES File Explorer), install the apk manually, as you normally would do.
Once it has been installed, go to app drawer and run ViPER4Android FX.
When you will run the app for the first time, it will prompt you to install V4A drivers on your device, so tap on Yes. As soon as you tap, you will have to grant root permissions, so choose GRANT.
V4A app will automatically detect the system and install appropriate drivers for the mod to work properly, and upon completion, the following message will be displayed: ‘Driver installed, please reboot your device’. And now as advised, reboot your phone/tablet (I hope you know how to do that!).
When the device has rebooted, again launch ViPER4Android FX app.
Tap on the 3-dot menu button on the top-right of the app, and select Driver Status. It should display Status: Normal.
