Viper4Android not installing drivers.

Hi, I tried to install viper4android sound mod but it is not installing. It says please check if the device is rooted or busybox is installed or not.
I am on PA 17th August and Franco kernel, with busybox and full root naturally. Is there any explanation or solution to install drivers?
I've tried:
°Uninstalling app and re-installing…
°changing Roms and kernels…
°turning on "safe mode" and "compatible mode" in the app
°deleting dalvik cache
°selecting A8 drivers and A9 drivers too (users said both work).
But still it won't install, it gives the same error if someone can be of help, I'd be really grateful thanks!

Make sure that u have installed busybox by opening that busybox installer app, people get confused by installing app only.
Rest I don't know, I have install this mod yesterday only working fine.

I had this problem as well, try downloading supersu and updating the su binary via TWRP. viper somehow worked after that.

Make sure you have the latest version by updating thru the in app settings. Also, superuser will not work. You must be using supersu for root.

Accurately :fingers-crossed:

Tied everything everyone else has tried still same problem including changing selinux to permissive. please anyone have a fix?

Uninstall existing Viper APK. Locate XDA thread with viper_v2.3.3.0.zip in it (it also has 2 more tweak zips) and then first flash viper_v2.3.3.0.zip and then the other two from recovery. This flash wipes davlik cache so it takes some time to rebuild on boot. Then install Viper driver and boot again. Done.

same problem on device never had before

I'm having this broken busybox or not rooted completely/correctly error trying to install any version of viper4android as well. I have always had viper on this tablet, latest complete install of firmware is when problem started. But I have tried all fixes as everyone else has including using a cached buybox apk from previous install just to make sure something hadn't changed in Stericson's busybox, no go.
This is a real head scratcher!

Here is what I found that fixes this:
OK all I have a fix for installing Viper on the Tab S.
Use any file explorer and navigate to /system/vendor/etc
Copy the audio_effects.conf in that location
Navigate to /system/etc and paste the file you copied there
Once copied change the permissions to match the other files in the /system/etc folder
Install Viper and it should work this time, apparently the audio.effects.conf file is expected to be in the /system/etc location and is not there by default for some reason....*"
Even though this file was where it said to copy to, contents were different. Either way, afterwards all I had to do was open the V4A apk and it asked to install driver, BAM........!!!!!!! Worked!
Zach

Dumb question, but have you made sure that you have granted storage permission in the Apps Menu?

like I said, my /etc had the file already as well, but by pasting over it, obviously changed contents, afterwards V4A installed drivers and worked.
I also found another mod that works, V4A FX, is 16ghz, but by downloading and installing V4A XHIFI, then installing the FX over it (you just activate the XHIFI, first check option under settings, then go back to FX), you get 32bit sound! Yeahhhh Baby!!!!!!!!

Can't get Viper V4a Sound Working

HI. Im having trouble getting Viper FX 2.3.30 working..
I can install, but after installation it prompts me to install the driver, (I pick high quality), I reboot, and then next time I run it, it asks again as if the driver is not installed.
System is rooted, busybox installed and app has root priveledges..
Anyone have any ideas?

I am using viper4androod on 910c with sweet rom. Viper4android is working good. I converted v4a to system app using titanium before setting up v4a.

Viper4android

is there someone who succes in the installation of this app?
when i open it,it ask if i want to install the drivers and stuck and after few seconds it crash
someone can help me with this ?

Many guys use this and there already was enough discussions, there are even seperate threads created with tutorials, use search for once[emoji14]

I managed to get Viper4Android working this way:
First off, I use stock with systemless root and xposed so the many security features included in stock made it a bit tricky. If you use a custom rom with a custom kernel, it's likely a bit easier.
I flashed my stock image from the google website
I flashed a custom kernel and then Supersu and then the lolliviper zip from this thread: http://forum.xda-developers.com/google-nexus-5/themes-apps/discussion-viper4android-t2543796
I installed busybox from the play store, opened the busybox app and let it install.
I disabled selinux enforcing using the app from this thread:
http://forum.xda-developers.com/showthread.php?t=2524485
Then I ran viper4audio and installed the driver from the app
Then I rebooted into twrp and used the terminal to delete /system/etc/audioeffects.conf and rebooted.
Voila, working Viper4android.

By the way, you can run a supolicy script for media server instead of disabling selinux because that would increase security risks and don't you mean audio_effects.conf in vendor? IMO better to add v4a entries than delete it, it's there for a reason I would think

[Honor 8 Nougat General 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.

Updated busybox and v4a zip is found here https://mega.nz/#F!HlpzlaZL!wGNoJinVPZL0YiBcdbLlKA
V4a should be more easy installed shouldn't give you driver I/O error anymore.

V4a zip more user friendly.
Same goes for busybox. No more struggle

[V4A] Viper4Android I/O Error (Driver Installation Failure) [FIX]

Hey everyone! I seem to have found put together 3 methods of installing/bypassing the V4A App on android. These methods include:
Regular Installation, and 2 Error bypasses/fixes.
If you get the error "superuser manager doesn't allow app to access su or you don't have root at all. fix this to use this selinuxmodechanger!", then you've come to the right place.
Requirements: ROOT, (maybe) TWRP (or anything you can flash the zip onto your phone with. With this tutorial I'll be using TWRP.)
If you don't have TWRP, here's the link to that \\ https://twrp.me/Devices/
Type in/select your device, click download, and flash it to your phone.
====================================================================================
Regular installation:
1.) Download V4A from Google Play Store \\ https://play.google.com/store/apps/details?id=com.vipercn.viper4android_v2_fx&hl=en
2.) Open, and grant root permission.
3.) Install drivers, and reboot phone. DONE!
==================================================================================================
V4A SuperSU Manager Error:
1.) Download V4A from Google Play Store (the newest one) \\ https://play.google.com/store/apps/details?id=com.vipercn.viper4android_v2_fx&hl=en
Open it, grant permissions, click "install drivers" <- just get through the driver menu. This is a troubleshoot test. If it fails, keep going on with the tutorial. If not, You're A-Okay.
2.) Download V4A Flashable ZIP from here \\ https://drive.google.com/file/d/0By-5wpCgi7OHMjFZRU1PYXljbDQ/view
Drag and drop from your computer onto your phone in your "Downloads" folder.
3.) Open TWRP and click "Install" and navigate to your "Downloads" folder where you Installed the V4A Flashable ZIP (Viper4AndroidMM_v2.4.0.1.zip)
Install the ZIP in TWRP, and reboot.
4.) Open your apps/app menu, navigate to the new (it's an older version, but it's newly installed) V4A. It should be a purple logo instead of a blue logo. At this point in the tutorial, you should have both the Google Play Store APK, and the TWRP Flashed APK. Open the PURPLE V4A, and Install drivers now.
5.) Reboot phone, go to the NEW (blue logo) V4A, and install drivers on that one too.
The rest is clean-up. You may now delete the older version of V4A (purple logo).
========================================================
Bypass/fix #2, The SELinuxModeChanger issue:
1.) Download V4A (newest version) from \\ https://play.google.com/store/apps/details?id=com.vipercn.viper4android_v2_fx&hl=en
2.) (Grant root access) Attempt to install drivers. If this succeeds, then Idk why you're still here.
3.) Download SELinuxModeChanger APK from \\ http://forum.xda-developers.com/devdb/project/dl/?id=12506
4.) Open it, grant root access, and click "Permissive".
5.) Re-boot phone, and open V4A when done.
6.) Install drivers!

Thanks
I had the Viper.apk from their website and the Google play version loaded also and I was getting the I/O error when trying to load the driver and the Google Play version didn't work at all. I did try to load SuperSU and busybox before attempting to load the driver again and it still didn't work. I don't know about permissive kernel, I'm running Resurrection ROM on a Rooted Note 3. The way I got this to work was to uninstalled the V4A Viper APK version that I had retrieved and loaded from their website. Next I booted into TWRP recovery and installed the V4A Flashable ZIP from the link that I found here. Next I ran the flashed version and granted SU permissions when asked during the install driver process. The driver finally loaded and bingo it works now.

You have to rename file before opening V4A app for the first time, now you rename it before or after flashing no matter,

When I install drivers for ViPER4Android FX I get "Driver installed, please reboot your device." and when I reboot, I'm asked to install drivers again. Did anyone figure out how to successfully install these drivers? I saw fixed around the forum, but they don't seem to work for me.
