Unable to extract and install Viper4android

Hi,
I want to install Viper on my GS4 i9500, i am currently running Aurora rom v7 based on lollipop 5.0.1. I tried dowbloading the zip for viper4android from XDA official forum (http://forum.xda-developers.com/showthread.php?t=2191223) however none of the zips were working; everytime i download and try to extract it says "bad zip file". So can anyone please point me to a working zip file for viper4android and also help me in installing and setting it up for the first time.
Thanks.

Mediafire link works and zip ok. Don't use your mobile internet to download the zip but a computer with broadband.

Hi,
Thanks for the reply, i have downloaded and installed Viper and its driver as well; however it is still asking to install the driver every time i open it. Is it a known issue ? If yes then how to fix it; i have followed the instructions as given in the official forum.

The point is that for Anhdroid 5.0 and later you'll need to set your kernel to "permissive". You can use "SELinux Mode Changer" for doing so, if you have no option to install a permanent "permissive" kernel.
BTW Please press the "thanks" buton at the bottom of my posts

Its still the same issue, its still asking to install/update the drivers and even after changing the mode with the the app you posted it still shows SELinux in enforcing mode. Doesn't standard Linux commands like "sestatus" work android ? How to i permanently set the SELinux mode to Permissive rather than Enforcing ?
Isnt there any config file for selinux where i can make the change and then reboot the phone ?

Are your sure about you granted root permissions for both apps? Which superuser app is actually installed on the phone?

How to install Viper4Android on S7 Edge?

Seems this guy has the answer on an enforcing kernel.
http://forum.xda-developers.com/s7-edge/review/audio-quality-t3336558

If you haven't seen this thread already, check it out. I successfully installed V4A on my 935F with it.
http://forum.xda-developers.com/showthread.php?t=3335007

And FYI... it sounds fantastic!

You DON'T need permissive kernel for v4a any more..after hundereds of trials and errors I just downloaded newest apk from original v4a thread, put it in private-apps folder then set correct permitions rw-r-r, restarted device and it works flowellesly ! I have stock enforced kernel.

Tried hundered of ways here as well,
Mine just keeps asking to install the damn driver all the time mate, and even if installed, after reboot - it just asks again to install/update the driver again.
Tried with the su.policy zip flash as well. Still cant get it to work!
Tried with the MM compatible newest APK and placed it in Priv-app. Guess that's what you did too. Cant figure out what I'm missing here.

It happens to me also.That means you did NOT properly root device.Error with constant driver install is because busybox..I rerooted device ,wiped data for SU, and granted permission to busybox again.DO NOT use any other Viper app then original one from thread !

Youv'e been a lot helpful mate,
I think I'm getting somewhere, Could you please tell me which busybox did you use?
Is it the Stericsson version, or the Meefik ?

Stericsson one. I hac problems as you did and concluded the most simple one was the best..All that modded Viper apps doesn't do any use.Just use original one,give permissions in private-apps, restart device and that is it

which music players support this? cuz so far all i see is status normal processing no

Men! You put so much hope in my heart. Please, could you be so nice and prepare step by step to do list? I personally would ask you about 'give permissionso in private-apps'. Could you explain? Do you copy v4a to priv-apps? Where from? What permissions? And about busy box: when I open it it shows me that it is installed in su/xbin... in what folder did you install busybox? And one about reroot: did you go to su and choose: full unroot before flashing su again? And what about mount namespaces: checked or unchecked in su? Have to tell you that I've tried so much different ways and still v4a doesn't work. I would love to try your way but please put some lights here. Thanks!

I've tried my best, in all possible variables and finally decided to give up after wasting 3 straight days of a perfect weekend.
My Driver just doesn't stick and I've tried all alternative installation methods. I've kept backups of system/*.* so all damages were reversed without any flashing. Root, Busybox everything runs perfectly and tested everything for integrity.
So far I've cornered the issue to Systemless Root, which seems to be the only entity having issues with v4a. Until a proper answer is digged up, I'm gonna stick with my Note 5 which has this working on System-Mode Root. (The driver didn't stick on the Note 5 when I tried to use it with System-less) Luckily the Note 5 is still on LP, with Su 2.64.
Good Luck to those who are trying, and thanks to all who helped!

OK...I made comprehesive tutorial here

Yes. Actually there is a perfect package from @guitardedhero. You have to be rooted, busyboxed, twrp'ed. Flash this: http://forum.xda-developers.com/attachment.php?attachmentid=3701983&d=1459364213
It is Viper Atmos Sony Beats edition working beautifully on ny S7E. Three more step to do after flashing: 1. freeze SoundAlive and AdaptSound, reboot. 2. go to system preferences and check whether Viper has memory access granted. 3. go to SuperSu and DISABLE 'Mount namespace separation', reboot. Done!
Btw. If you want to play with Profiles inside Viper, go to your internal memory using root explorer and inside Viper folder create folder called 'Profiles'.
Btw2. 6.0.1new abowe destroy your conf files. Hope you have backup.
Better flash @guitardedhero mod on fresh rooted rom. hope you enjoy.
Btw3. Sound is AMAZING!

Thanks for your reply!
Just after I asked for help here, i found a driverless package from @guitardedhero that worked! Glad to know you did it too, mate! :highfive:

Working but 10 second later turn normal mod
Why do you think's going on?
For example in youtube, 10 second viber4android active, later deactivate.

[BLN-L21] Viper4Android on EMUI 5 Beta?

Hello everyone,
2 weeks ago my Honor 6x arrived and today I finally decided to unlock the bootloader and root it. Until now everything worked more or less fine (I can't remove preinstalled Swiftkey for example), but there's one thing that really annoys me. Viper4Android isn't working. I tried every trick I know and managed to get it to installing the driver, but after that the status was "Abnormal" Does someone know a solution ?
Thanks in advance

I downloaded guitardedheroes viper for Android from the honor 8 forums. I use kernel adiutor mod (not playstpre version but version from XDA ) to set selinux to permissive. Also don't forget to rename audio_effects.conf in /vendor/Etc to audio_effects.conf.bak

I tried as you said but now since installed as system app (and yes i uninstalled the other version before ^^) V4A doesn't ask for root access and without that it can't install the driver.

Thread closed per OP request.

Problem installing viper4android.

Hi guys,
I am using the optimized stock rom located here. aaaaawawawaa using BitO-KU kernel. The sound is very low on my Nvidia Shield k1. I have done the tweaks located here. In the thread it says that viper4android makes a big difference as well. When I try to install viper4android I keep getting an I/O error when trying to install the driver. I downloaded SELinux changer but when I launch it I am getting an error in it as well. It says the app was unable to gain root access. I checked in supersu and SELinuxModeChanger does have root access. So I don't understand why it will not work either. In terminal emmulator it says that permissive mode is enabled. Can someone please let me know what I'm doing wrong? I would really like to get viper4android working.
Thank you,
Rocky

1. It isn't good rom, I've had it only two days. Stock kernel is better too.
2. I'm on stock 5.2(K1), rooted with Magisk 14, installed M modules:
V4A 2.0 by ahrion, busybox by osm0sis. V4A works good but I don't need it for speakers. @grimreaper1014
Do you have properly installed busybox?

Just flash Viper4Android using Magisk 14 (its located under downloads tab) and disable AudioFX if you even have that on stock ROM. Then it should work but note that if you get processing error just create a folder named "MagiskManager" and it should work then.

Ok thanks guys. Right now I have SuperSu flashed via recovery. Do I have to remove that somehow to install magisk?

I'm doing a clean install. I'm going back to LinageOS. Where do I create the MagiskManager folder at if I need it? Thanks again for your help fellas. I appreciate it greatly.

@grimreaper1014 create the folder in /storage/emulated/0/ in case it doesn't want to install the module. If it goes without any problems then congrats you have working Viper4Android !
(Make sure you disable AudiFX app in lineageOS before you do any flashing)

If for some reason you (or others) choose this route, you can remove SuperSU (mandatory in order to install Magisk) using the built-in function in the SuperSU app.

Similar setup: stock 5.2 ROM, with Magisk 14, and simply installed the V4A (version 2.0) module by ahrion. I think the module installed busybox (by osm0sis) automatically, as I don't recall doing it myself. But I maybe I'm not remembering that properly.
V4A working great, no messing with SELinux.

Cant get Viper to work properly

Hey guys,
since i got my Oneplus 6, i couldnt get viper to work quite right. Most of the time its just shows "Processing: No" till i restart it and after like a hour or device switch it turns off.
I tried:
Copying the Audioeffects.conf from system/etc to vendor/etc
Using Magisk Audio Compability Module
Using Alternate Magisk V4A Module
Using a Magisk Rom with Build-In V4a (currently xXx 2.8)
Disabling Dirac and Services
but nothing worked
thanks for your help

i had the same but then i tried to use the other viper release from magisk and it worked. there is this one called hifi and fx

Try exiting the viper app with the 3 dots top right hand corner. That is what worked for me

Sounds to me like you need to disable the battery optimizations for Viper. It's almost as if your phone is detecting High battery drain and shuts down the app

yeah thats what i thought too, i zried whitelisting it and installing it as system app (+ magisk module) but it didnt seem to work.
I removed the one from my rom and tried the magisk repo version again and somehow its working till now

I'm using the Android p beta and i don't have the problems with viper as i did with oxygen os 5. it's always processing for my headphones, either plugged in or Bluetooth. the only exception is sometimes after receiving a call while listening to music, after the call is over and my music resumes, viper is no longer processing. not every time though. i used the latest magisk and the viper module in the screenshot.
i also didn't make any changes to conf files, just installed through magisk download. rebooted, opened viper fx, gave it storage permissions and turned it on.

Had the same problem, but was able to resolve it by choosing the legacy (non-material) interface when installing the Magisk module. I still flashed the full module and selected the latest version, just not the material interface. It may have been something else, but I've updated my ROM (HavocOS) several times and even done a couple full fastboot stock resets and the issue is yet to resurface.

I've had this problem on an Samsung S7 Edge, S8 Plus, and now, a Oneplus 6.
Everything appears to look good on Driver Status, except "Processing:No" and it's audibly not on.
What's worked for me in this specific situation is replacing the configuration file "audio_effects.conf" in /system/vendor/etc with another configuration file that I found in another XDA thread. So here's the concrete steps:
1. Install the viper4android FX module from Magisk manager that has four devs (v1.7 as i write this) and reboot. I don't know if this method will work with other v4a modules. Note that Processing will work temporarily, but likely won't survive a reboot.
2. Download this file (files_for_v4a.zip) from here:
https://forum.xda-developers.com/ga...laxy-s8-s8-t3596933/post72049061#post72049061
3. Unzip files_for_v4a.zip and make note where it extracted. (You'll need one of its contents, audio_effects.conf, later)
4. Using a file explorer with root capability, go to the following directory:
/system/vendor/etc
5. Copy the existing "audio_effects.conf" to another directory, for example /download, to use as a backup in case this goes badly
6. Copy the file "audio_effects.conf" that you unzipped earlier to /system/vendor/etc, overwriting the existing file.
7. Reboot and test v4a.
Good luck!
Note: The Pulse feature of a custom NavBar in custom ROMS based on LOS 15.1 will not work if you do the above.
Although I'm just a hack, I modded an "audio_effects.conf" file using commits from the above to work with Pulse. I've tested it on my device (despite my lack of know-how, it seems to work for me and others!), so be aware of this if you download the following file and use it (by renaming it audio_effects.conf and placing it in /system/vendor/etc):

I haven't messed with dirac at all, and v4a still works for me.
Some clarification, please:
Did you uninstall the v4a magisk module that came with xXx and reboot?
Then go to magisk manager and install v4a fx materialized1.7 and follow the rest of the steps outlined in my post?
