[Samsung Galaxy S7 Edge Guides, News, & Discussion] GODSPD:
Here is a complete guide on how to get V4A stock and V4A Sony Beats Edition working on your Samsung Galaxy S7 Device. Please note I have tested this personally on my own S7 Edge SM-G935F and it is working 100%. There was a few bumps along the way to get everything working and if it wasn’t for [MENTION=4445176]guitardedhero[/MENTION] help and everyone else involved I wouldn’t have figured it out. There were similar tutorials HERE and HERE that offered some insight but didn' provide a fully working procedure so I put together my own guide that will work for sure.

You will need a rooted device for this to work (SuperSU by [MENTION=631273]Chainfire[/MENTION] CF-AUTO-ROOT) and a working recovery TWRP version 3.0.0 or above found HERE

As usual please backup all your data and files (internal and external SD cards) as mistakes can be made and things don’t always go as planned :p

0.	In your SuperSU app go to setting and deselect/un-tick “Mount namespace separation” (this is causing issues with the installation process on this and other devices)

1. Install BusyBox by Stephen (Stericson) with the default settings of /su/xbin

2.	Install the latest version of Viper4Android (currently 2.4.0.1) from the official website - LINK or if you prefer use the older version as it has been favored for providing better quality. (Do not open just yet, only install)

2.3.4.0 with its Super Quality driver is absolutely superior to 2.4.0.1 and its driver in every aspect, it's almost not even fair. I promise you, this build will absolutely blow your mind, especially when used with the ViPER|Audio™ Audiophile™ 4.0 Profile [MENTION=4445176]guitardedhero[/MENTION]

3. Make sure Viper4Android has write permissions (this should be on as default but check just in case) Settings -> Applications -> Application manager -> V4A -> Permissions -> and make sure all available options are enabled.

4. Freeze the stock Sound Alive or Adapt Sound app using

Titanium Backup

.

5. Open up Root Explorer (or your preferred root browser) and change the system to MOUNT R/W

6. Go to

root/system/etc/

and rename the file audio_effect.conf to audio_effect.conf.backup

7. Download the modified audio_effect.conf from HERE and copy it to

/system/etc/ and /vendor/etc/

(This last location will have no files, it may be skipped?)

8. Set permissions of the new files to rw-r-r (0644) (important! Or you may have boot loops)

9. Change your system back to MOUNT R/O and exit.

8. Restart your device in recovery and flash THIS FILE HERE and reboot (I didn’t perform any wipes)

9. Once your device reboots, open up V4A and grant root permissions and install the requested drivers.

10. Reboot once again and this should be it…

You should now have V4A working on your device :D

If you feel the stock V4A isn’t giving you the correct audio niche or experience then consider changing to ViPER|Atmos™ 4.8.1 Sony™ Beats™ Edition by [MENTION=4445176]guitardedhero[/MENTION] – (I have not tested other editions found here on the OP Thread, they may or may not work… any volunteers :) ??? )

FLASH THIS FILE TO GET STARTED ViPERAtmos 4.8.1 Sony Beats Driverless.zip

Once your phone reboot you will have a new looking V4A icon and upon opening it should work but your Dolby Atmos app will keep crashing until you FLASH THIS FILE dap_r6.5.zip - Fresh Dolby Atmos App file.

And here is a quick guide written by [MENTION=4445176]guitardedhero[/MENTION] to enable the Audiophile profiles...

I don't recommend others to flash without an acceptable backup to restore as this build drops compatibility big time for some devices resulting in no in-call volume for example. It is the custom version I built for my Nexus 6 ViPER|Atmos™ Audiophile™ rom and is just absolutely incredible!

Post-install instructions:

In v4a:

Menu > Show Notification (disable through notification shade if you wish)

Menu > Ui Setting > Expert

Menu > Save Effect Profile > As New Effect > Stock

Download and extract ViPERAudio Audiophile Profile 4.0 zip from the OP attachments section or HERE.

Search in:

/data/media/legacy/ViPER4Android/Profile

and

/storage/emulated/0/ViPER4Android/Profile

until you find the Stock folder you just saved earlier.

Take note that this is your working v4a directory.

Copy the Kernel and Profile folders in the ViPERAudio Audiophile folder you extracted earlier and paste them into the /ViPER4Android folder of your working v4a directory. Compare the folder and file permissions to the Stock folder and files and set them to the same permissions if necessary.

In v4a:

Menu > Load Effect Profile > Audiophile 4.0

Recommended Dolby Atmos™ Settings:

Music tab highlighted at the top

Open or Flat EQ preset

All three effects at the bottom turned Off except for Dialogue Enhancer if it sounds good to you.

Troubleshooting and additional steps will be written here shortly...
