I used my own method on a galaxy s7 edge SM-G935S so your mileage may vary. This is not 100% fullproof but I've done this 2 times and it works well... of course with a little bit of troubleshooting.
1. Of course you'll need a rooted s7 edge (s7 maybe) and TWRP recovery.
2.From Playstore download and install latest STERICSON BUSYBOX. Install busybox in default su/xbin and give root permission.
3.Download the unofficial Viper4android from the play store.Here's the link:https://play.google.com/store/apps/d...id_v2_fx&hl=en
4.Install the drivers for the unofficial Viper4android app (don't reboot yet)
5.Download App Disabler - https://play.google.com/store/apps/d...disabler&hl=en
5.5: Download this file - https://www.dropbox.com/s/k9cnruw2e1...olicy.zip?dl=0 and flash it.
6.Reboot the device
Here's where it gets confusing :silly:
7.After you reboot, enable viper4android and pick you're settings, test it with the google play music app, if you see no difference, use App Disabler to disable Adapt Sound and Sound Alive (and possibly reboot, it depends on your luck); if you hear a difference, you'll notice that the audio is weird sounding, don't worry we're in the right direction.
8.Now uninstall the Viper4android drivers and reboot. After that, uninstall that app.
9.Download from official page Viper4android version 2.4.0.1 from forum.xda-developers.com/showthread.php?t=2191223
10. Using any root enabled file explorer app of your choice copy Viper4Android in folder PRIV-APP and give it permission 0644 rw-r--r--
11.Restart your device
12.Open V4A and install driver when it asks...don't exit app or DON'T TOUCH anything else, just restart your device.
13.Now set your viper4android settings and test it with your music app. It should now work perfectly
14.If it isn't working, try repeatedly ticking and unticking Adapt SOund and SoundAlive in App Disabler and restart your device many times (again, it depends on your luck), you can also go to system/etc and replace the audio_effects.conf with the one that the developer has posted - www.arter97.com/browse/S6/M/ViPER/ i know it;s for the S6 but it will be ok.
Let me know if it worked, good luck.
Sorry if my English was a little broken, I'm a Vietnamese guy and I'm in a bit of a hurry:silly:
Or you can just flash this http://forum.xda-developers.com/showpost.php?p=66040780&postcount=80
Thanks man, I didn't know this method before i did mine and had to go through alot of trouble to get viper4android to work....by the way, is it working with the samsung stock music player (samsung music)?
I've got busybox installed properly, it's Stericson's, I've checked if it's working and it is, I have given root permission to V4A and I have plenty of space for the drivers to be installed. I'm on a rooted h959 15e image, I'm not really willing to revert back to previous software versions, and I'm stuck with this problem. The exact message I get is "Driver install failed: The busybox installation found on your device does not work. This usually means you installed a wrong or broken busybox. V4A needs Stericson's busybox to work. If you are sure you installed busybox properly, then please confirm your device has been completely rooted". But it is rooted, I can access all types of root-only things like xposed and root booster. SELinuxModeChanger is set to permissive, I have tried with both V4A apps from the DXA thread and from the (not the FX one) one in Google Play, and I have already tried uninstalling and installing everything, and I have also tried reflashing my rooted_system.img countless times. So root is working, busybox is working, SELinuxModeChanger is properly set up, why isn't it working? Also I noticed something, when I reboot my phone, SELinuxModeChanger changes the SELinux mode back to enforcing, but if I turn on the option to show a notification after the mode changes, the notification IS showed, so it must mean it's working, right? I have tried before without poweramp and dolby atmos, but as of now I'm using both. I don't even know if V4A will work with Atmos and Poweramp (Atmos and Poweramp do work together, though), but I just need to try it, even if it means uninstalling atmos. So I'm completely out of options. The only thing that I can think of is if there's a way to manually install the drivers (latest updated/updatable super audio quality ones), but I don't know if that's possible. So anyway, can anyone help me with this?
You should flash a zip from this site: http://forum.xda-developers.com/nexus-6/themes-apps/viper4android-t2952137. I used this: http://forum.xda-developers.com/attachment.php?attachmentid=3667403&d=1456929089, and it works. Of course, flashfire v0.24 is required.

I'm flashing the zip file viper|atmos 5.5 sony beats edition with flashfire 0.50, and nothing's happening. Again, SELinux mode is permissive and busybox is installed, but atmos app and viper app won't show up, and when installing the app from the playstore, it says the driver is not installed. Help, please?

1. First, install ViPER4Android apk from the official site: http://forum.xda-developers.com/showthread.php?t=2191223. You can choose between the old (v2.3.4.0) and new (v2.4.0.1) version.
2. Then flash a zip from this site: http://forum.xda-developers.com/nexus-6/themes-apps/viper4android-t2952137. I used "ViPERAudio 5.4 Stock.zip" (compatible with V4A v2.4.0.1). You can also choose "ViPERAudio 4.7.1 Stock.zip", if you have V4A v2.3.4.0 installed. I didn't try other mods (such as "viper|atmos 5.5 sony beats edition"), so I don't know if they work.
3. For flashing, you have to use FlashFire v0.24, other versions don't work with the device. Link: http://flashfireapk.com/flashfire-0.24.apk.
* Also, you don't have to change SELinux.
Thanks

Thank you very much, friend, I'm gonna try your method right now. Just one question, why doesn't flashfire 0.50 work with the g flex 2? I flashed Xposed with it and it worked. Isn't 0.24 an older version?
How do you test the benefits?

Actually, I don't know. I've read somewhere that v0.24 is the only working version for our flex 2. I didn't want to brick my device, so I used v0.24. I've had no problems with it so far.

I'm just going to play my flacs and listen to them while tuning v4a to my liking.

I've tried with version 0.24 and it didn't work either. I'm gonna test the g flex 2 flash mod (the one with g4 tweaks and etc) with flashfire 0.24, since it says to use that version and it didn't work flashing it with 0.50, and if it still doesn't work for me, I'll revert back to 0.50, since it worked flashing dolby atmos (seperate from viper4audio, but the viper4audio-only zip file didn't flash). I fixed my problem of drivers not installing, so I'll just install atmos again and install the v4a drivers through the app. But thank you all for your help, really . If I menage to get all the mods I have working, I'll make a thread so that H959 rooted 15e image users can enjoy the best experience in their G flex 2.
maybe you never get viper4 to work in GF2...i did it many times with diferent methods and never never get it to work...even use the flashfire 0.24 (the only working to install zips on GF2) you never get a driver to work!
i recomend to you install Dolby Atmos see Apps section in this forum of GF2...the Dolby Atmos works like a charm and do the good job as Viper4.
(i am not sure but because of architeture of the SD810 Viper4 the latest version never will work on our device!)
That's strange... I'm on H955 v15c, V4A 2.4.0.1 with "ViPERAudio 5.4 Stock.zip" installed using FlashFire v0.24.
Everything works.

Everyone... I... I... I FINALLY GOT TO GET ALL THE MODS I WANTED TO WORK!! *dances frenetically* :laugh::laugh::laugh::victory: I'm gonna make a thread so that every user with a h959 G Flex2 can enjoy this tuned experience I achieved! Thank you all for your help! If you guys are interested in knowing what mods I managed to make work on the latest software version of the G Flex2 (that is, on the h959 ones), keep an eye on the thread I'm about to make! *celebrates into oblivion* (erm... this is embarassing... I'm a newbie here and... um... how exactly do I "close" or delete this thread? I mean, my problem is solved so... what do I do?
Install busybox from google play, set selinux to permissive and You guys have to uncheck an option on supersu app. Option named "namespace separation". After uncheck that option reboot phone and try to install viper driver again.
I installed the iSiddharth Lollipop ROM of Xperia C well it actually changes the basic layout like menu,lockscreen,settings but can't use to install lollipop required apps(it shows 5.0.1 though). Now I went for xposed installation, downloaded a zip and flash it but nothing happens then found another zip flashed it over previous one (because of no backup) and it worked I updated framework to latest version and was able to install all apps. None was working. I tried installing Youtube background play,instagram zoom and download, 1 click video downloader.Activated all and reboot the phone and no effect of any app. So I uninstall all of them and removed the xposed using system app uninstaller(as I had no backup).After all this I need to know is there any simple working way to installed xposedI was unable to download xposed modules of lollipop
The thread title says it all. Does anyone know why V4A won't install properly on OB 12? If you install the drivers and reboot, it just asks you to do it all over again on reboot.
Install busybox with magisk, try use v4a legacy version. Try different v4a versions

I discovered the culprit for this. It's AML ( audio modification library) it's simply not compatible with v4a on the newest one plus firmware. As soon as I removed a AML, viper installed
On latest Oxygeon OS 10.3.4 having issues installing ViPER4Android legacy from Magisk.
It keeps asking to reinstall the driver....succeed, reboot...and back to the same message to reinstall the driver.
Does anyone have it working? What did you do?
ViPER4Android 2.7.1 install and Tasker automation
Managed to install the latest ViPER4Android 2.7.1 on Oxygen OS 10.3.4.
Installed the APK which creates a Magisk module and you can then update it from there.
You can find the latest version here: https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx
Driver installs with no issues and seems to work fine though all profiles got converted to the new format it uses in 2.7.1
Tasker automation also broke since the app commands changed to kill/reload it. For anyone interested, these are the new shell commands to use in Tasker to automate bluetooth profile switching in Tasker.
Code:
cp /sdcard/Android/data/com.pittvandewitt.viperfx/files/Preset/Headphone1/bt_a2dp.xml /data/data/com.pittvandewitt.viperfx/shared_prefs/bt_a2dp.xml
killall process.ViPER4Android
am start -n com.pittvandewitt.viperfx/com.pittvandewitt.viperfx.MainActivity
Launch app: Spotify
Run each as root. Repeat for each device you want it to switch settings for. These actions are activated when a bluetooth headset connects.
Hi all.....I have TWRP recovery and latest magisk installed on my S21+ working fine but can't get the viper4android driver to install
I heard there is a way but i have been out of the loop with this stuff for a while. i tried various flashable nonroot zips to install the driver it did not work. Also tried from within magisk plugins also not working. The App is there and runs just not the all important driver to make it all work, anyone know how?? I aslo tried audio modification plugin from magisk and trying to force permissive mode not working at all...no luck so far.
Got it working by installing the attached version of viper4android AFTER everything listed below.
hope it helps someone else
Also have under magisk modules
Audio compatibility patch
Audio modification library
SElinux permissive
