I did some quick research and what I could see says the Samsung S23 is the same 64-bit only so try the version in the link I posted, uninstall the old version and remove the magisk module and reboot, then download the two files and install the apk and flash the module in magisk, reboot and you should be good to go
[Android Apps and Games] oso2spot:
You're amazing! <3 Are there any special instructions for installing this? I saw somewhere else that there's a whole process, including installing Audio Modification Library, rebooting several times, uninstalling then reinstalling stuff again, etc.

EDIT: Just did the research necessary, the only thing required is to install Magisk Module then the apk, no other steps! For anyone wondering, the only version that works for 64-bit phones is the link bombadier posted
[Android Apps and Games] bombadier:
Always important to provide information about your setup if you had said what device you had,also wrote instructions on how to install, a solution could of been found sooner glad you have it sorted so if my posts helped please hit the thanks 👍
[Android Apps and Games] syedhadi98:
I got this error while installing the Repackage one. How to solve it ?. Btw, I install it on Magisk Alpha and using MIUI 12.5
[Android Apps and Games] zgfg:
I use Repackaged on MIUI 12.5 and never had a problem.

Using also on another phone with MIUI 14 (previously it had MIUI 13), also no problem

Due to your error:

"Cannot find audio config"

You may have a problem with latest Magisk Alpha - they have changed again some mounts that affect and break certain modules

Did it work with earlier Magisk Alpha versions?

Switch to official Magisk (Canary) or Magisk Delta, you should have no such errors there
[Android Apps and Games] Yahoo1:
Works great on my Pixel 7 with Android 14. Thanks, @bombadier.
[Android Apps and Games] timbook2:
Thanks works well on my POCO F4 arrow os 13.1
[Android Apps and Games] MaziCr4ck13:
Hi, I have trouble when first start with the app. It does not proceed to install the module and delivers a message saying "Error: nomsuch file or directory " I hope you could help me. This happened since ROM changed. Only once happened into my current rom
[Android Apps and Games] AGA27:
Can someone help me while installing a driver there's an error showing Error: No such file or directory. I also tried the one name programminhoch10 but same problem.
[Android Apps and Games] bombadier:
Always helpful if you provide more information like device etc, If your device is 64 bit only then you will need this version, most things work and installation is as easy as following the instructions
[Android Apps and Games] AGA27:
Oh I have a Xiaomi Redmi note 7 with custom eu ROM. Yes I have a 64 bit but supported with 32 bit ARMv7.
[Android Apps and Games] bombadier:
Try the 64 bit version that I linked, am assuming your device is rooted with a working magisk install ?
[Android Apps and Games] AGA27:
Same problem. No driver found.
[Android Apps and Games] bombadier:
Strange, you downloaded the two files and followed the install instructions? Think there is something wrong with your magisk install which is why the driver install is failing
[Android Apps and Games] AGA27:
I don't know what's wrong I follow all the instructions correctly on all versions and developer versions. I have a Magisk 26400 installed and working perfectly fine.
[Android Apps and Games] bombadier:
In magisk is the re engineered module enabled? I would check the log to make sure all modules are being loaded as that is where the problem is, both times you have tried to install viper it's failed because it can't find the driver, that points to magisk
[Android Apps and Games] AGA27:
I don't have that option. I'm using stable from topjohnwu.
[Android Apps and Games] bombadier:
How do you know magisk is working then ? did not know that the stable version does not have the log tab in the app where you can see what is being loaded etc
[Android Apps and Games] AGA27:
I know cause I use it on other app. If you mean log yes I have a log but unfortunately I already removed my vfa-re. But the one you said re engineered module. I don't have that.
[Android Apps and Games] DiamondJohn:
The logs are still taken, and can be viewed
[Android Apps and Games] bombadier:
Bit confused, you need to install the Re viper app AND Flash the module in magisk, if you didn't Flash the module then the app will not work? Instructions tell you what to do.....

I thought that was the case, user I was trying to help told me there were no logs so couldn't check to see what was being loaded
[Android Apps and Games] AGA27:
I tried to install it again and this is the installation log.

[Android Apps and Games] bombadier:
Install the app and reboot the device, should be working when you restart your phone, look under the log tab in magisk to see if the RE module is being loaded if it is open the app and see if its working or if you get the same error
[Android Apps and Games] Zreux:

[Android Apps and Games] rippledrums:
Soooo... Don't mean to nag but will there be a light version now on this "new" app? :angel:

Been waiting for that for the "old" one... :p

Anyways, keep up the good work :good:

EDIT: ooohhh I just noticed you made the current Substratum theme work with this one and looks great! Amazing work! :good::good:
[Android Apps and Games] zoel.fahmi:
Wow, it's now supported oreo

Good job, guys
[Android Apps and Games] Ragnar Eldur:
Oh not a big fan of this "please install the original APK" thingy that I got stuck on after making an effort to change the grey colours to black with the APK editor like I've always been able to do with most apps including the previous materialised module. Looks so much better for those who really like pure black AMOLED themes with some vibrant nice accent colours. Would post that APK for those wanting the same.
[Android Apps and Games] Ragnar Eldur:
This would also be a splendid idea if possible, this is from the IDM+ Download Manager. Nice feature to completely customize the look of the app. Then you can submit it online so other users of that app can easily apply it with one click.
[Android Apps and Games] mrjuniork:

There is a Substratum theme available for this app in XDA Labs that has AMOLED options along with several accent colors.
[Android Apps and Games] wildbeer:
Hi, many thanks. I installed RR 6.0.0 on my RMN3 pro and then magisk and magisk module 2.6.0.2. It works like a charm but when I restart the phone it does not work never again...

What can be the problem?

Thanks for all!
[Android Apps and Games] Team_DeWitt:
We're making a very similar idea as what that app has, but it doesn't have the highest priority right now as there are important bugs to iron out first. But it's definitely going to be there in the future, so make sure to keep an eye on the xda labs page!

LG g5 rs988, Nougat 7.0 stock LG. V4a tells me to uncheck dvc in Poweramp,but it's grayed out (rom not supported). Last version of v4a for magisk worked before. Not sure how to fix dvc problem. I've reset Poweramp, but to no avail...
[Android Apps and Games] Team_DeWitt:
I can't say with this amount of information. It may be helpful if you pm me the zipped in magisk module + logcat (upload to a decent cloud service and send the link)
[Android Apps and Games] Team_DeWitt:
If V4A can process you can ignore the warning. If that's not the case, I can't help you and you should ask the developer of poweramp what's going on.
[Android Apps and Games] Azto_ZiFlow:
Is it work for ViperOS 7.1?

Sorry for my question, i'm newbie:o
[Android Apps and Games] neekless:
I gotta say I'm not a fan of the new UI. I prefer each effect opening it's own page, like it used to. Right now with all the effects and all their settings in one page it's just a huge mess imo.

Edit: couldn't find 2.5.0.5 materialized anywhere so I went back to old non-material 2.5.0.5. couldn't stand the clutter.

what's the current version of this mod
[Android Apps and Games] icecoldsipra:
Latest version is 2.6.0.6. For some reason, XDA still shows the older version 2.6.0.5. Not sure why.
[Android Apps and Games] flamedrops:
it doesn't work with Huawei phone begins with android 8. :(
[Android Apps and Games] rippledrums:
The source code for the driver is not available and newer Huawei devices require a 64 bit driver which doesn't exist, that's why it's not working.

Sadly, without the source code, there is no fix as far as I know.

About the Uninstallation of ViPER4Android FX

Uninstallation

Remove the driver using the entry in the navigation menu... can someone tell me where is that ? cause is not working for me thank you !

i'm on my samsung j120w cfw...

Don't know if a do that right.. first time i post here, don't post much in general...
[Android Apps and Games] bomcoi1402:
Many thanks !!!!!!!!!!!!!!!!!
[Android Apps and Games] gloeyisk:
I'm facing this also when first time. But it's fixed so far.

I just force close the Viper4Android app, re-open and re-install the driver. Then voila....

I've notified for reboot the phone and driver installed properly. (If you wondering how to check the driver just close the Reboot notify, open Magisk Manager; Modules section and there're available Viper4Android FX module already installed which is written 2.6.0.6-stable as version). Hopes it help.
[Android Apps and Games] nahean.ahmed:
I think its not working on my asus zenfone 2 laser z00l.

I attached driver status screenshot. is there any way to ensure whether it will work or not.

Currently on viper 0S 3.1.1, android version 7.1.2.
[Android Apps and Games] pupun47:
Oh,. Thanks. I will try that
[Android Apps and Games] gloeyisk:
As far as I know...

Did you have disabled stock AudioFX or MusicFX? Can you try to disabled it first and check? Thanks.
[Android Apps and Games] nahean.ahmed:
There is a app with this rom called "equalizer". It cant be disabled or uninstalled. I turned off its service.

Actually i m not sure whether this viper4android is working or not. I didn't find/hear any improvement of sound. Maybe i dont know the best setup or its not working in my device.
[Android Apps and Games] kpirnie:
Everytime I open the app it prompts me to install the drivers.

Honor View 10 - US

Magisk rooted.

Any ideas?

If you use/install Titanium Backup app, so you're good to go for disabling those Equalizer app.

Can't install the drivers.... now currently trying with magisk i'm on my samsung j120w , no success yet , NEON Enabled: No.... if anyone can relate ? thank you
[Android Apps and Games] karlouch:
Viper4android

I put "audio_effects.conf" from "system/etc" to "system vendor/etc" (i guess thats what i did..) i can now see on driver status : Version : 2.5.0.4 and "NEON Enabled: Yes" SUCCESS !!! but my audio still don't get affected......i try so far with vlc ,black player and play music don't know if different player make any change ?

Maybe changing "audio_effects.conf" for "audio_effects.conf.bak" will work, root explorer don't let me rename it...i don't know... any ideas ? thanks you
[Android Apps and Games] flamedrops:
Because huawei latest model has no driver for v4a.
[Android Apps and Games] AGA27:
As I expected. Same error nothing change. My device is all good. I don't know why v4a is not working on me. Maybe I will just install my Poweramp Equalizer again.
[Android Apps and Games] AGA27:
Module are properly place and audio_effects.conf and other audio files in my system/vendor and etc/lib and lib64/soundfx are patched so nothing is wrong but v4a are always asking for driver.
[Android Apps and Games] bombadier:
I am at a loss what is going on, unless there is some device specific voodoo at work here,the module is loading but the app cannot see the driver has been installed, was just looking at the issues section over at github and see you have added your comment about it, must be a device/rom thing as I see that issue was opened by another user using an Xiaomi device, there was another magisk module that would not work on Xiaomi roms I am sure.........
[Android Apps and Games] AGA27:
Yeah I added a comment there you will see it cause I'm using a same username on github and xda. I'm hoping they'll find a solution on our problem because I want to try v4a. This module is top rated on sites and as a audiophile I want to try it badly but installation is s*cks
[Android Apps and Games] bombadier:
Sorry for your troubles, yeah Viper was always a bit of a battle to install but since I switched to the RE version installation could not of been more simple, at least on my device.
[Android Apps and Games] DiamondJohn:
As a last ditch TEMPORARY check, have you tried switching to permissive?

Checked you logcat?
[Android Apps and Games] AGA27:
What? Permissive? I don't know how?
[Android Apps and Games] AGA27:
Oh I see. SeLinuxModeChanger. I think that's a little bit not safety. App is a little bit outdated.
[Android Apps and Games] DiamondJohn:
And thats why I said TEMPORARY! In pas5 ti8mes, this was one of the common reasons for failure of Viper. If it is this reason, t5hen it is easy to fix.
[Android Apps and Games] AGA27:
At last I install it on my phone I use the version of programminghoch10 and I pair it with Audio Modification Library. I will post what I do for everyone looking for answer.

First download all the file then flash first the AML but don't reboot, go back and flash the V4A module don't rush go back again ang disable AML Module don't remove just disable it. And at last you can reboot your phone now, open V4A don't install it the app is included on the module, just wait. If V4A is still looking for a driver just press ok and grant root, go back on Magisk and enable AML and reboot your phone and viola. Thank me later guys enjoy V4A.
[Android Apps and Games] Hello34:
The download via XDA-Labs is down or something. Could you reupload it?
[Android Apps and Games] dkachhot:
After magisk installation, the app is stuck at 22% at installing drivers, I talked with a friend and he told me after seeing the installation log that there is a regex error while installing the module, "sed: bad regex '^\s*#.*$': trailing backslash (\)" can anyone help me to install the module successfully

Does Viper4Android Repackaged work on A14? I'm not using a Pixel and I'm on a custom ROM
[Android Apps and Games] ffejy462:
Yes. It was recently updated for a14.
[Android Apps and Games] Extreme_Ninja2099:
I'm talking about repackaged not viper4android RE (Reverse engineered)
[Android Apps and Games] SchWeinSAuG:
same here. stuck at driver installation at 22%.

did you get it working ?

programminghoch10 version should not need AML to work from what i know. i got it installed instantly on my Op8pro @A14. cant get it woring on my dads pixel 6a @A14.
[Android Apps and Games] dkachhot:
Nope, I dropped the installation now
[Android Apps and Games] SchWeinSAuG:
thanks, but doesnt work

still installation stuck at 22%
[Android Apps and Games] bombadier:
Have you tried the RE version ? thats the one I would recommend for your Pixel, there is even a material version which looks nice
[Android Apps and Games] SchWeinSAuG:
yes, RE version works, but no convolver, what makes v4a useless for me.
[Android Apps and Games] AGA27:
Try this easy method. My first is complicated. Just download all the file and install AML first then reboot. After reboot disable it and install V4A by programminghoch10 and reboot. After reboot wait for V4A app to install by it self and open it and V4A will stuck at downloading just exit or cancel it and enable AML again and reboot again. That will work now.
[Android Apps and Games] SchWeinSAuG:
thanks for input , but doesnt work.

installation stuck at 0%.
[Android Apps and Games] AGA27:
Did you disable AML on Magisk before installing the module?
[Android Apps and Games] SchWeinSAuG:
sure, i did it exactly as you wrote.

pretty strange. on my Op8pro with Derpfest A14 i just installed repackedhoch77 module and all good.

on 3 different pixel phones i cant install it.

installed jamesdsp on pixel. works instantly.
[Android Apps and Games] AGA27:
Look the file on your AML folder under data/adb and locate them on your system folder and see if they are patched or exist. If not there's something wrong on your ROM. The location of the file are different from AML or V4A. I uninstall V4A so I can't explain what to look just look at the folder under data/adb.
[Android Apps and Games] SchWeinSAuG:
well its stock android on pixel. no custom rom.

how can i tell if the file is patched or not?
[Android Apps and Games] DiamondJohn:
MD5 comparison between the source and what is mounted

You can also run the mount command in a shell to see all of the mounted files.
[Android Apps and Games] AGA27:
Just look on their date if they are modified. Simple as that.
[Android Apps and Games] DiamondJohn:
Dates and file size are not reliable. File checksums are the way to check.
[Android Apps and Games] sic0048:
I just wanted to say thanks to all the developers who have resurrected V4A from the dead. V4A was one of my "go to" apps to install after rooting my phones. The loss of V4A support was one reason I stopped rooting my phone for the last several years. However I just picked up a P8P and immediately rooted it (mainly for the ACC module). I was pleasantly surprised to see the reengineered version available. I simply installed the 0.6.1 Magisk module and 0.6.2 apk as directed. No other modules were needed (like they were back in the day). It seems to be working just fine.

So thanks again! Job well done!
[Android Apps and Games] cjnaz:
OP11-5G CPH2451_14.0.0.201(EX01), Magisk-rooted, on Verizon.

TL;DR: Is there a known solution for the 22% hang problem?

Downloaded ViPER4AndroidFX-repackagedhoch77-864fafa.zip. After install, clicked V4A app, said "No driver found, Do you wish to install", click OK. Granted Forever SU priv in the Magisk popup. Installed exited and I rebooted (don't recall if it asked for a reboot). After reboot I see that in Magisk SU list that ViPER4Android FX SU switch is off. Turned it on. Started V4A app, still says "No driver found, Do you wish to install", click OK. Hangs at 22%.

Hum...

Per https://github.com/programminghoch10/ViPER4AndroidRepackaged, the latest release was Aug 5, 2023, and its tested only on LineageOS.

Has anyone diagnosed what operation is hanging at 22%? I saw a note about an RegEx error.
[Android Apps and Games] Saicoth:
Yes, there might be. The problem with that is the latest Magisk. Download Magisk 25.1 rename it from apk to zip and from Magisk manager install it as a module. Reboot and now Viper will install the driver and reboot, but after the reboot, driver is still not found.

For some reason Viper is impossible to install on some phones. Wasted a whole day trying everything.

Got a Poco F5, tried both A13 ROM and A14, it won't work.

Redmi Note 5 with android 11 works after installing V4ARepackaged, no need to install any driver, after module install and reboot viper just works, as it should be. If you're getting driver not found, there is little you can do.
[Android Apps and Games] DiamondJohn:
And what did the logcat say?

And as best I know, I only install the latest stacker Magisk, and I have 26.4 installed, not 25.1
[Android Apps and Games] Saicoth:
Magisk isn't causing the problem on my Redmi Note 5, I use 26.4. However, when using 26.4, Viper faces issues installing the module/drivers. Upon opening the app, an error occurs, leading to a stalled process. Reverting to version 25.1 resolves this issue, and everything functions as expected. I'm talking about the installation method which I remember using for years now, install viper apk, open it, no driver found, install and reboot.

As for ViPER4AndroidRepackaged, this is no longer necessary. The installation through Magisk and a subsequent reboot ensures that everything is set up and ready to use. But on newer devices V4A has trouble installing, I've seen countless messages on V4AFX telegram group regarding this driver installation loop and there's no solution atm.
