I tried lolipop version, Im on 5.0.1
Is there any way to make it working?
I only use it on spotify.
Or is there any other good app/equalizer?

Well, is there a problem with flashing the .zip or does the app dont work properly?
I used this (first two .zips) and this.
If that is still not working you should try that too.

The app works ok, but the sound is the same, its like doesn't have any effect.
I'll try lá ter.
Its not only Q&A but a thread with the app funcional to ower device.

I got V4A working by using the zip/apk standard download, then installing the apk as usual (making it a User app).
Install the V4A driver.
Make sure your Compatibility Mode is set to Normal.
Reboot.
Install SE Linux Mode Changer app from the Play Store (or edit your build.prop) to switch your SE mode to Permissive. (L's default is Enforcing.)
Open V4A up and tick the Enable box to use V4A on the ”phone speaker” tab.
Play some music! Check to see if it is working by unticking the phone speaker Enable box.
*If* it still doesn't work... Try the following one at a time:
Set Compatibility Mode to Compatible.
Tick the Force Enforce V4A under the phone speaker tab.
Install as a System app instead of a User app.
Try a different music player app. I'm using Shuttle+ and it works perfectly. I've heard some player apps don't work as well as others though.
Hoping this helps you a bit. It seems to be one of those trial & error things to get Viper set up on Lollipop. I even have to do things a tad differently to get it working on my Nexus 4 & 5.
?

Ty worked Great. I didn't Changed to permissive.
Maybe some moderator could move this thread to Q&A?
?

Hello, I flashed all three zip files from the first link but upon rebooting, v4a continually force closes. Don't have any other sound mods.
I'm on 5.0.1. Any help would be greatly appreciated.
Thanks.

The last .zip from the first link is outdated. Try to delete it and use this one.
Make sure you use the right .apk for 5.0 (should be A4.x).

Hello, thanks for the response. However, v4a kept force closing constantly and continually so I'm not able to navigate within the device. My biggest idiotic move was I didn't make a nandroid....assuming all will be good.
Anyways, I'm now on a hunt to flash stock rooted rom. If you have any info on that would greatly appreciate it.
Thanks.

OK all the file flashing is not useful at all if ur running stock. The only reason they exist is for DIFFERENT DEVICES, meaning ur flashing crap that is meant for something else and can have bad consequences. The flushable zips all have scripts that add lib files or script to build.prop. The flushable zips also seem to mess with any app that handles kernel configuration. ie if u like to change clock speeds, nothing would stick on this tablet after I flashed those v4a zips. Would always revert to stock.
For v4a to work. FIRSTLY run selinux mode changer. The person that said they got this to work without it is wrong. Dead wrong. The driver will NOT I STILL OR INITIALIZE UNLESS SELINUX IS PERMISSIVE. This must be done to allow android to install the driver to the kernel. Period. Run selinux mode changer, set to permissive, reboot. Check selinux, sometimes u will have to do it 3-4 times for it to stick. Then install the newest v4a from their site I think it's @ 2.3.4.0 the older versions needed the flashable zips for some files the Nexus lollipop update didn't have. They fixed this. Now just install the app normally, then open it and install the driver. Reboot. If u r on cyanogen unlock the developer options and turn off or unchecked "use nuplayer" finally, if u use gone mad music player go to options, audio, tell it to use external dsp.
Profit!
I've never needed to use compatibility mode or anything else. Works like a champ.

[Q] Magisk v16 Problems T715

Hi all, i'm using a stock rom, rooted with magisk and debloated (manually). I always faced this problem, the 90% of the modules i try to install ends with something like that:
See Screen below
However i've never asked help because i tought it was a Magisk problem resolvible with an update...but every update ended always in the same way for me when trying to install some modules. I've also attached some logs here of when i tried to update xposed systemless if someone could help me it will be really apprecciated!
P.s Anyone facing the same problem? I've read somewhere that a similar problem is common with Motorola devices but idk if this is the case

Is this via Magisk manager?

Yes this is via Magisk Manager, however the same error (could not mount something) appears also when i try to install a module via twrp. The "best" thing is that some module just works both way (Busybox NDK for example) while other fails both ways. No module work in a way and doesn't work in another. So basically if a module work in magisk can be installed also via twrp otherwise it cannot be installed, no matter what i try

I have the same problem. Trying to install viper4a.
I have no clue how to fix it

I think this is a bug in Magisk with the way some modules attempt to install and mount, which is why some work.
I'm surprised though that they don't install in TWRP. Is your device encrypted, can you mount /data in recovery?

Well as far as i know, if you're on stock rom you won't be able to install audio mods because they're in conflict with something in the Rom. You should use a custom rom instead. However not sure 100% about this, maybe some audio mods can work, but you should ask someone else, i'm not so informed

AdAway with temp root

I have an unlocked bootloader with TA-Backup like described in this thread.
But to get my banking app working I only want ro use the stock kernal.
I use the newest firmware: G8441_47.2.A.10.28_1310-4373_R3C
Is it possible to install AdAway if I boot with a different kernal with root and activate the host files?
After a reboot the stock kernal will be used with working adaway.
Does this work?

Better option for you on that situation is to use a dns proxy for ad filtering
something like this app
https://f-droid.org/en/packages/org.jak_linux.dns66/

Yes I use a app like this, but the problem is, that sometimes it takes up to 1 - 2 min till it is connected to the DNS Server.

Have you tried if the banking app works with magiskhide and "hide magisk package name" from magisk settings?

Yes, I tried this, but as I read in some other threads, this will only work with newest Magisk.
But then I have to recompile the kernal for myself.

@DripleX, If you like to check if magisk is causing your (banking) apps to detect root, you may try this:
j4nn said:
Dear @albenex, although I would also assume it should be possible to resolve this with use of magiskhide and other settings, I've uploaded not-pre-rooted kernels for the latest fw version into my experimental folder here.
So you can clean up all traces of magisk (factory reset may be needed to be sure) and use a boot-*-47.2.A.10.45-hideunlock.img kernel to test it. Also be sure to run unmodified stock fw.
Click to expand...
Click to collapse
These kernels are not pre-rooted with magisk but include the patch to hide bootloader unlock.
That should provide you setup very close to still locked phone (if you have your TA-locked restored).
If the app is working with the *-hideunlock.img kernel, magisk would need to be made hidden to get it working with a rooted kernel.
If it did not work even with the not-prerooted kernel, it would mean BL unlock is detected some other way (most likely using your Android Attest key - assuming you have it "provisioned") as it seems to be the case with google pay.
A donation was received on Tue Apr 30 15:03:03 UTC 2019 - I assume it has been from you @DripleX.
If so, thank you.

Thank you @j4nn for your reply!
I will check this after my vacation.
And yes, I made the donation

Viper4Android FX doesn't work

It calling me all time for the driver. I do that every time and I give him magisk root to do that. Any suggestion?

Did i get here some help or not? Then i looking maybe for a other Forum...

Install as system app and allow it to install through the not recommended settings.
U now have to delete it and reinstall it.. Watch the instructions in the thread pls before you become sow passive agressive mate. It is not our fault, ok?

Use this module. Flash in Magisk manager. Choose latest driver, material app, system app, lib workaround, and choose no for the last. (I don't remember what was it)

Hi, I've a Mi9 and tried to install Viper4AndroidFx.. Installation ok, driver installed, but no effect.. tried to set all to highest value to ear some difference but nothing..
Uninstalled it, i tried Viper4Android Legacy, installed as system app and by magisk and chosen all installation option with up volume button..
But still no difference with the stock speaker.. can you help me?
I would like to encrease the volume during a calling. thanks bye

take a look on mi8 or mi a1 forum in xda, there is described exactly which modules in Magisk must be installed to allow a proper function of the ViperFX. Still bootloader locked, so I cannot support by then.

It only works with unlocked BL ofc. Did you tried installing "Audio Modification Library", and "Audio Compatibility Patch" from Magisk repo?

make sure to have installed Magisk Manager, also latest Magisk root installed via TWRP. After this it should be pretty simple, look for the afore mentioned modules in Magisk install them one by one (each single one might require a reboot). After installing them you may install ViperFX, (version 2.3.4 as a system app).

hi, I tried to do everything you said, no one difference..

in a few days when the unlocking time will end will try it myself and in case will make it work, I will post here the process steps.

You have to install the legacy version with lib workaround. For me its working or you can try the rootless version from team_dewitt (look here in xda for it) you only need twrp and init.d injector.

Try this one.

Just to install the apk, nothing else.
Working here like a charm

Hi, I tried the version linked by pokko, it works, but I can't find the way to encrease volume, it works just to have a lower volume, If I set the master volume value higher it doesn't encrease, seems like the stock volume.. is there a way to have an higher volume for the speakers?
thanks

2.7.0/2.7.1 working great on MIUI but with GSI roms it's a different story

if someone can tell me how to get an higher volume please let me know soon.. I'm really thinking to remove root frome my phone.. I've found no one good reason to have it, I don't want to change rom, so I did it just to have 3 things: adaway, encrease volume and use ps3 controller with bluetooth...
adaway doesn't block anything in site that I tried it,
with viper4android my speaker volume is still the same..
miui seems not compatible with ps3 controller.. sixaxis compatibility checker can't works with bluetooth..
the only good thing I've found is the modded youtube version with no ads and background player.. but I've seen exist a versione for no rooted phones too..

Question OneUI 4.1 Android 12 Viper4Android

Has anyone managed to get viper working for any devices on OneUI 4.1 SELinux Enforcing? I tried everything but nothing worked, and I don't want to set SELinux to permissive. Help is appreciated

I haven't tried installing it on OneUI devices, but had a lot of troubles getting it to work on my Oneplus. This discussion has good instructions on how to get it working. I personally did not used it, as I tackled this problem before it was created, but most of the steps from this instruction I remember doing.
Just in case, have you tried enabling legacy mode in settings?

The issue with Viper on OneUI 4 is the installation of the driver, no combination of Audio compatibility magisk modules worked, no matter what you do Viper is never able to install the driver, meaning that you can't even access any settings in Viper because the driver install prompt pops up every time you open the app.

That's strange. Is Viper magisk module just not getting installed? Only thing I can suggest is to try to install it using Zackptg5 installer.

The magisk module installs but the driver doesn't. And the rootless installer can't really be used because there's no twrp available for the tab s8+. I tried an app which supposedly can flash the zip bit it didn't work
