Help With Viper4audio: Driver install failed

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'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.

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.

[Huawei P9 Nougat info/guides]

So I've been getting lots of different questions about how to get this and that on android 7.0 nougat so to make it easier for everyone to find ill create this thread.
1. TWRP
Is twrp available for N? If so where can I find it?
http://forum.xda-developers.com/p9/how-to/twrp-3-0-2-0-n-t3506947
2. ROOT
Oh cool now I have twrp. So how can I root?
Download phh r275 version and flash
Download and install Material phh apk: Release post
Now you should be good to go. If any issues feel free to ask here or in phh official thread.
3. BUSYBOX
User friendly zip flash this and the below steps isn't needed!
Flashable zip (1.25.1) : https://mega.nz/#!zlRm3S4B!9rAtfi0wI8oFu6xjJITgF0dRwV21UPsxvZQZzMo6VXk
This one is a bit tricky. If you run root. But
Download jrummy's busybox on Gplay.
Select installation folder to /system/xbin or if u don't want to touch system folder use /sbin if available. U can replace jrummy''s busybox with stericsson version if you like it better. But you must have installed jrummys version first if you're booted into android. Else stericsson busybox might have issues installing. Or u can use zips which contains busybox Google busybox flashable.
4. VIPER
More user friendly if using this zip the below steps should only need se Linux mode changer!
Flashable zip: https://mega.nz/#!f8wlzIrB!vVCAv-xqWB8lOrcQTgIyFL0WS7MFsE9iFb08E1YKV2Y
Is quite a mess to get working. You need se Linux mode set to permissive. Flash guitarheroes version of v4a (2.5.0.5) once flashed you need to replace the audio effects in /vendor/etc/audio_effects else you'll get I/O driver installation failed. Copy the .so files to /system/lib and /system/lib64 and set correct permission. If you have wrong busybox message. Try different versions of busybox but I use latest from stericsson and it works great. Hope u get it working.
Oh and don't forget to allow sd storage access or you'll get driver I/O error as well. And se Linux changed to permissive use se Linux mode changer for it. It works great with phh!
5. MAGISK
As it seems to be now. Magisk won't work due to loop issues on boot. And mount seems to have losetup fail 1 on mounting a .img while booted.
6. Xposed
Not yet available. Be patient rovo needs time we can wait for him
7. comes soon.
More stuff.

how does your audio_effects.conf look like? i used one for aosp from "ARISE+Sound+Systems+Deuteronomy+2.3.3.zip" and got it working but don`t know if this is the right one for our device (huawei phones).

It doesn't matter if it's aosp. Since it is for v4a it will work. As long as the audio effects works it doesn't matter.
Also I just finished my hopefully new nougat viper4android zip (i made my own for M with material designed version for my s5 neo) which worked fine until now.
Now it extract all files to its locations even to /vendor partition which all zips I used previously never had. I'll also update busybox zip which previous available is 1.24.2 which I'll bump up to 1.25.1.
I'll also going to upload my stuff to android file host. But that will be later

How did you installed ARISE in Nougat?
I've been trying all day and I'll always end with an I/O or Busybox error. I tried a lot of things, like changing /vendor/etc/audio_effect.conf to audio_effect.conf.bak or installing Busybox into system/bin, but none of them seems to work for me.

Do you know, is your Viper4Android installer compatible with the following rooting/Busybox configuration:
- L09 c432/b378
- TWRP 3.1.0-0
- SuperSU-v2.79-201612051815-EMUI5.0.zip
- Rummy"s BusyBox (installed to /system/xbin)
as described by @hakaz and @Atarii in the post #102 and follow-ups:
https://forum.xda-developers.com/showpost.php?p=71588837&postcount=102
Also, should SELinux really be switched to Permissive mode for V4A to work on P9 with Nougat?
Thanks

Having Magisk, can you now also install Xposed?
PS: Please provide links to your resources and threads.
Btw, you have P9 Lite - does the method for Magisk apply also to (regular) P9 (single SIM)?

it workes because we have a modded boot.img created by @HassanMirza01, ask him what he did so as to he will do the same for p9 boot.img(or anyone else)
install selinux and set it to permissive, after that install magisk app via playstore and click on autoinstall
no xposed isnt working because there is no xposed for Nougat.

Trying to get Viper4FX sound mod to work with my Honor8

Hey guys,
I'm into the Android from the very beginning and I would love to get rid of a problem which is driving me crazy for some time
I was trying to flash the Viper driver to get the great sound quality again. I'm now on the latest nougat.
Already unlocked the bootloader, rooted it and flashed the TWRP. Saw an thread about how to install it properly on the Honor8 and I did everything correct in my opinion.
I have the 1.26.2-meefik busybox now installed in system/xbin path (which seems to be working correctly overall) and otherwise everything seems working good except that when I try to open the Viper it says that I don't have root OR that i have to install the driver, and after pressing yes my phone just reboots and does the very same thing as previously.
Am I missing something?
Feel free to ask something more if you need.

I had this same situation, just kept installing the driver, reboot, repeat, making no progress... I finally got mine to work thank goodness! Are you remembering to use a root file Explorer and go to /vendor/etc and rename the file named audio_effects.config to audio_effects.config.bak after flashing but before installing V4A? That was my main problem. And you have to be sure to do it on a clean setup, so if you've already installed V4A you need to clean out and start again. Also u need a kernel auditor to set selinux to permissive upon boot. These two steps are key...

need help with magisk root, twrp and xposed (update 2017)?

Hey all,
Just purchased a LG U2 and now trying to make it work in the way i want it.
All informations here seem very old, so I wanted to open an update thread, with all what is possible on th lgu2, while
I found only very outdated informations...:crying:
So far:
First I setup the watch with AW2.0, after that flashed twrp 3.1.1.0 and supersu wear 2.82
I managed to get busybox installed and wanted further add Xposed.
There my problem starts, flashing xposed didn't work out.
So right after that, I switchd to Magisk root, to try work with the modules supplied.
(Steps -> use script UnSU, after that flash boot.img again, than flash MAgisk through twrp)
But after that the same with the modules. I try to install busybox, magisk tell me its no magisk module (i've downloaded the module and pushed it on the sd through adb, while the download button isn't reachable in magisk dialogue menu)
in twrp the module tells me there is no magisk installed.
so how can we go on from here? is there a way to make it all work?
did somebody try to change dpi and download the module directly through magisk? does it work?
also if somebody could help with an updated list of sideload able full android apps?
would need an email that can handle at least two accounts directly on the watch (please not advice outlook, its working from the phone i know)
thanks to all in advance

did it this time without and mgisk works so far fine. granting access for total commander no problem.
but now another thing. i installed now busybox from the repos in magisk, he say installation successful, but the module isn't there after reboot?

Viper4Android Not Able to Install OB12

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.

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.
