Anyone able to run Viper4Android?

I just got my OP3 and really like it. I'd love it with V4A... but it's not working. The driver doesn't load.
When I try to load SELinuxModeChanger, it errors out saying that it's unable to gain root access (even though SuperSU grants root). Weird.
So is V4A working for anyone?

Yep. I have busy box installed.

Try using A.R.I.S.E on XDA, it is a full package with a lot more than V4A. Furthermore, try to set your linux to permissive.

dont use superuser 2.74
use 2.67

^ I think that I'm trying to use v2.74. I'll find v2.67. Thanks!

Confirmed fix. I'm now running v2.67 (Beta) and I'm now able to run V4A. Thanks again, kramer987.

Setting it to permissive worked for me, that may help others as I do have v2.74 installed.

THREAD REVIVE! (Happy July 4th to those in US)
I thought that I had V4A working, but it isn't - even though it says that it is. How do I know? Regardless of what you do with the FIREqualizer, the sound remains the same - clearly unchanged. Has anyone run into this?
To recap, this is what I'm running:
* OOS v3.2.0
* SuperSU v2.67 Beta
* Busybox v1.24.2-meefik
* SELinux (set to "permissive")
* V4A v 2.4.0.1
* Google Play Music v6.10.3019C.3013175 (phew)
Here's what I see when I run the driver status check:
Here are other screenshots of V4A that shows the rest of the settings and me changing the FIREqualizer. Throughout, the sound doesn't change.
Now I have heard that OOS v3.1.2+ uses an internal sound driver called DiracHD so 3rd party sound drivers cannot be used. Since XDA members are more knowledgeable, I request either confirmation or a suggested solution.

I am running Divine beats by @TheRoyalSeeker.
Viper and Dolby Included.
Good sound..!

When I flash anything, it doesn't get installed properly. That includes Xposed, Divine Beats. It shows install success in TWRP but it doesn't install.

That's strange try a another twrp recovery specially Garak's one. And try to dirty flash your ROM again or check permissions in file manager or maybe try mounting system in twrp and flash.
Was your phone bootloooping and has systemless root.
Try these and tell me your progress.

That isn't necessarily needed as I am running v4a and Dolby as well.

Same problem here. Cannot install viper drivers, 2.76 supersu, busybox on rails, cannot figure out how to set selinux to permissive.

This is most likely because you HAVE to mount system in TWRP before you install divinebeats or viper via zip file. It will say it's successful, but nothing gets written to the system partition unless you mount r/w prior first. I cannot say this for xposed, but I do know that the only 'systemless' version worked for me was 85.1 by RomRacer.

You just have to mount system in TWRP, than you can flash divinebeats or xtrememusic mod or anything else. Im running v4a on this setup:
OP3 Lite rom 3.2.0
SuperSU - 2.76 (systemless)
Xposed - 85.1 (systemless)
XtremeMusic - 7.5.2
Viper4Android - 2.4.0.1

A little help, will using this module not damage my hardware?
Also, ELI5, how is it better than the default setup on my OP3, I searched ARISE and read what was there, but it turned out o be too technical for me.
Any help is appreciated.

This will not damage your hardware, unless you change the EQ to boost too much the sound of course, like for every mod. Furthermore, ARISE installs some audio libraries issued from Sony, HTC, etc... with Dobly app and Viper4Android. Everything is linked in order to have a good sound audio. Furthermore, some profiles are included in order to load them directly in V4A.
I suggest you download the Exodus 1 with Aroma installation since it's simplified.

Great work, I really had waiting for this a very long time. One question, if I uninstall the SELinux app it affects Viper?

Thanks, yes it needs selinux enf. Deactivated in order to work. But you can also activate the developer mode in the Viper app (settings - dev mode), there is an option (that i didn't test) that change the selinux state. I think this change will persist and you will not have issues whether you delete the selinux toggler app.

Does it works with a custom ROM?

ViPER FX (2.5.0.5) Materilized
I'm glad to share this little file that gives a fresh look to the ViPER4Android App, thanks to @pittvandewitt (the guy who makes the beutiful theme) and to @moonlightdrive (the sir who makes a port to stock 7.0).
It works on any ROM and of course, on stock.

Both of you: thanks a lot for this development. It works like a charm and installation is as smooth as butter!!
Just need one information: lockscreen visualization and pulse don't work after installing V4A (as musicFX and AudioFX are removed). Is is possible to get V4A with these two customizations or any of them? (Just asking the tweaks if available as like pulse and not intended any development enforcement.)
I'm on AEX ROM. Thanks in advance.

Sorry for the delay, wasn't at home.
Well in that case, if you're on AospExtended i pressume that you have Magisk Installed, and if you have it, you can install the ViPER4Android Magisk Module by ahrion.
I used to use this Module when i was using LineageOS (with pulse activated).
v4afx_v1.4.zip
Edit: i forgot to mention that you have to dirty flash your current AEX to get MusicFX/AudioFX again and to remove v4 scripts and files located into system.

Hello Moonlight,
Thank you a ton for your swift response. I have dirty flashed the ROM and then flashed V4Afx module, however the issue remains the same. Probably a clean flashing of ROM would resolve. Will try it later this week and update you the status.
thanks again for the tip.
Rgds,

I'm on ViperOS LOS 7.1.2 with root and magisk.
Tried to install via Magisk module but nothing happened, phone reboot after install but the apk didn't show up.
---- UPDATE -----
I've installed the ZIP some post above and worked like a charm

thank you very much. After a lot of searching for the viper mod, the only one that worked for me was this one. Xt 1621 Nougat stock 7.0, busybox and SElinux toggler, elementary kernel 1.04. Thanks for a little I go back to M.M.

Did you follow all the descripted steps in this guide?
It's mandatory to install BusyBox (use the version that i uploaded in the OP) and the SElinux enforcement must be deactivated.
If you're still facing issues, read post #11.

Yea, I tried all the steps in every Install Option out there. I have been Rooting and Flashing for Years but this has me stumped! I have a full version of the latest BusyBox installed, but I will try the version that OP suggest. As far as the SElinux enforcement...It won't let me deactivate it???

SELinux enforcement must be turned off in order to work, otherwhise the v4a_fx driver will not be properly loaded. The app ("The SELinux toggler") keeps the enforcement disabled (and this should remain in that way, all the time).
I had issues using normal versions of BusyBox, so that's the reason why i recommend that specific flashable version posted in the op.

•Graphic Equalizer which enables you to customize your sound across the frequency range from bass to treble.
•Volume Leveler which delivers a consistent volume, regardless of change in content or applications based on the device's master volume.
Bass Enhancer which improves bass response via headphones and device speakers, boosting the ability of both to reproduce low-frequency sounds.
•Dynamic enhancer which identifies the audio content and adjusts several parameters based on the audio content to give the best output quality.
•Surround Virtualizer which creates realistic surround sound through any set of headphones or stereo speakers.
•Dialogue Enhancer which improves the clarity of speech in any type of media
[Requirements]
Your lenovo k5 or plus must be running on a minimum of Android 8.0 Oreo for this app to work on it. Here's how to install Android 8.0 Oreo on lenovo k5
•Magisk users have the option of installing directly to /system instead of creating a Magisk module using the included arise_parameters.prop.
•SuperSU users with the systemless root solution have the option of creating a SU module instead of installing directly to /system.
•SuperSU users and Magisk users instructing a /system installation via a prepared /sdcard/arise_parameters.prop are encouraged to confirm that a minimum of 100MB of /system space is available before beginning installation in recovery
•Magisk users performing the default Magisk module installation and SuperSU users performing the optional systemless installation will require 100MB more than the minimum available /data space acceptable (usually 500MB; 500MB + 100MB = 600MB).
•Permissive SELinux Mode is currently required and will be set automatically after each device boot. Do not install archive if this is not acceptable.

That's good , BTW he is not the dev ( the guy that who posted It )
So I don't think reporting it here will have any effect just wait for new build maybe it's fixed and one more thing are you using v4a or any other audio mode because it might not be compatible with that.

Or you can just use the Magisk module for it.

i've been curious about this... when I attempt to load the module from magisk, the viper app states driver needs updated and i follow the prompts but every reboot same dialog stating update driver. after some further reading, i evidently needed to download busybox, also available as a magisk module. ok now busybox and viper... no more "driver update" needed, but i'm not convinced viper is actually working with any setting in the viper app (ultimately im looking for louder headphone volume)
>>> what am i missing? do i need another module? custom kernel?

This is the only version I've found that works. Doesn't work well switching between audio sources though.

Do you need root for this to work?

Yes

Have you guys installed the Audio Modification Library as well? This helps a lot with getting V4A to work properly.

i've been curious about this... when I attempt to load the module from magisk, the viper app states driver needs updated and i follow the prompts but every reboot same dialog stating update driver. after some further reading, i evidently needed to download busybox, also available as a magisk module. ok now busybox and viper... no more "driver update" needed, but i'm not convinced viper is actually working with any setting in the viper app (ultimately im looking for louder headphone volume)
>>> what am i missing? do i need another module? custom kernel?

I tried it but v4a wouldn't work with it installed. I uninstalled it and v4a started working again.

Installed AML after and it removed Viper app, still see it in Magisk. Deleted everything and now when I install driver, Viper app disappears.
Update: installed APK from OP on that thread. Kept magisk module installed. Working

I keep getting the, update driver for V4A. I've done it like 5 times. I had busybox installed first even. I also installed ViperXHiFi, and it keeps asking for V4A driver to be updated... I'm going to test in my car anyway, but something is off for sure. This didn't happen on my 2 xl.

Yep! I installed V4A through the Magisk module, after SELinux and Busybox and a reboot. In settings, went into developer mode then disabled SELinux. I'm guessing yours works? If yes, what were your steps?

Not processing but I can hear effects when toggled

Is this one different than the Viper FX Android Magisk module? The material, 2.5.0.5 or something like that? That's the one that worked on my 2xl, so, I repeated the steps that got it working on my 3xl. I tested in my SUV, and, sure doesn't sound like it's working...

Yes it is different it looks like it's a newer version with the higher number and all....
The FX version would not install the driver. It doesn't work
So I take it you removed all audio mods flashed the module in mm and rebooted. Then you installed the recommended driver when prompted and rebooted? If so, are you sure the driver is installed by checking in the Viper app?

I'm not sure what you are referring to as far as me removing all audio mods? I simply flashed the one version of V4A FX after busybox, rebooted, and I get a prompt every time I open it to install the driver. Every time I do it, it says successful and reboot. When I click no and check the driver status, it shows it's not correct. So, doesn't look like the driver installs at all.
I guess I'll remove it and install the one you posted. If that works, color me happy. Have you tried it with Viper XHiFi? I used that on my 2xl when dolby wouldn't work on Pie. Didn't sound AS good, but still a big improvement, even over just regular viper.

Question V4A on OOS13

Hello,
has anyone managed to get V4A working on OOS13? If so, how?
Thanks for the answers, I won't be updating until someone confirms V4A works.

ViperFX for OxygenOS12/ColorOS12
1. Install AML and ViperFX 2. Reboot. 3. Launch Viper and install the driver. 4. Without running Viper: - From the archive AML.rar replace post-fs-data.sh along the path /data/adb/modules/AML - From the archive Viper.rar replace post-fs-data.sh...

Followed this and it works fine, but sadly Dolby doesn't work anymore

Hi I know its an old thread but, which phone did you use. I tried on OP8 Pro and it didn't work.
Edit: nvm. I didn't realize which phone forum I was on.

JamesDSP has a working version for OOS13. Unfortunately V4A is not yet good.
But JamesDSP is probably even better, because it supports lossless format.

Got an OP 9RT on same hardware and make V4A works.

Maybe you should install BusyBox from Magisk repository first.
Install AML & V4A modules
Install V4A app (do not run it!!!)
Reboot
Run the app
Use "Legasy mode" in settings
Start any music
Go to Viper and turn it on/off/on
It may couse bootloop. Use it on your own risk!
Dolby works fine too.

Thank you!!! Works perfectly!
Did kill my Dolby however but I'm really just happy to have V4A again. A couple times it did stop working but clearing the app's data and opening it again works fine, no reboot needed.

"Playback Gain Control" and some other controls are grayed out. Are you getting that too?

Viper4android is popularly considered to be the all time greatest android audio mod. Imagine an equalizer on steroids that requires ROOT and custom driver. Honestly other than a couple kernel tweaks here n there V4A is my only reason to root nowadays...
