[Q] Viper4Android FX on rooted Z3C with locked boot loader?

I have been using V4A for some time on my Android devices... Now finally when the Z3C could be rooted without loosing the DRM keys I went for it... Everything works just fine after the root, but I am totally unavailable to get V4A to work for some reason. Anyone that have this working with a rooted Z3C and locked boot loader? If you have, how did you manage to do it?

On my Xperia Z it worked just fine with a locked BL, I don't see why it would require an unlocked BL. My BL on the Z3C is unlocked so I can't say anything about that.
What problems are you having?
Sent from my D5803

Thanks for your answer Dsteppa... Well, I have this rooted Z3C and downloaded the latest V4A together with BusyBox. The driver and BusyBox installs just fine and I'm able to change V4A under sound settings... But I can't get the V4A to work. Whatever changes I make to it there's no change in sound. E.g. on my S3 everything was working just fine.

OK... I must be missing some fundamental configuration then... Did you only install BusyBox and then the V4A driver for it to work?

What ap are you using to listen to music? Don't forget to change V4A to your default MusicFX (Settings > Sound)

Hi... I have changed settings and using BubbleUPnP. Also tried the Walkman app but no difference in sound

Can you confirm that @ Settings > Sound > Music Effects V4A is default?
And did you enable V4A @ Headset/Phone Speaker/Bluetooth etc..

I have V4A installed, can confirm it works with bubbleUPNP and power amp. When you download the zip and extract it, make sure you install the largest file, then open and install the drivers. Then follow what Dsteppa said... It should work
Cheers ?

Hi and thanks once again for your concern... Yes, I have tried both the V4A FX and XHIFI and enabled them in Sound/M Effects and also enabled V4A for e.g. Headset. I've installed and used V4A on nearly 10 Android devices prior to this one without any issues at all. The strange thing is that I can see that the driver is active but not producing any change in sound... I also tried to reset the phone, also did the root process once more but the same result... Really strange as I see it.

Hmm then the only thing I can think of is you asking in the V4A topic, they should be able to help you there. Because it should work without a problem.

I have the exact same problem, viper4android installed on my D5803, rooted with locked BL, but not working. After spending some time trying to figure it out i found out that it doesn't work with the Walkman app, with google play music it's working fine. Hope that helps. I'm curious if you guys got it working with the walkman app?

Mine worked fine with Walkman, but I prefer PowerAmp (So I use that)

Thank you for your answer, after more digging around i found out that it's working with Walkman app too, but only on the phone speakers, it does not work with the headset. If you go to driver status (on headset) it says processing no, and it does nothing, you can't feel any difference, i have to mention that i use a pair of Sennheiser momentum in ear, and have not tested with anything else. On the phone speakers it says, processing yes, and it's working...

I bought the XPERIA Z3C for its native support of High Resolution Audio (HRA). This is the problem why it's not working for me... I found out that when playing a 24 bit FLAC file the V4A driver just won't process?! It worked fine on my Galaxy S3 (i9300) but not on this. 16 bits FLAC files play just fine, but when I play HRA files the sound processing just wont happen. I don't know if it's related to that it's a separeta DAC (Wolfson 1811) in the S3 and the Z3C uses the Qualcomm 801 with embedded DAC.

I'm having problems too.
Rooted my z3c especially for this and it's not working.
I've installed the drivers and then the app asks me to reboot, after the reboot I've entered the app and again, it asks me to install drivers like I never did.
Any idea on how to fix this?

Put V4A in compability mode and it will work probably

it's because of your busybox, it's either not installed or not properly installed, had the same issue.

Hi can yous confirm if this increases ringtone volume?

It's because of your duel recovery and rooting method, if you install busy box it might most likely erase your recovery on xperia z3. It happened to me actually but Viper android fx will work, if you prefer Viper android fx and no recovery go 4 it and install busy box from Google play you do a backup then reinstall your recovery via computer then restore your data from the backup
If you have duel recovery on xperia z3 or z3c it most likely has a different busy box compatible with that recovery

I solved Viper android fx not working with duel recovery on xperia z3 XD all I did was set selinux mode to permissive and it didn't ask me to install drivers again and again it works now

How can i increase the Headphone Volume, like the P9 Lite?

Hi, i got new Headphones today and i test it in my P9 Lite 2017, the sound is ok but not louder, i test it in an iPod Touch 5 gen, and my JBL T290 sounds Amazing, and i want to increase the volume in my Huawei P9 Lite 2017, i tried install ARISE but is impossible, just doesn't detect the props, and i tried viper4android but it doesn't install any driver anyway i found this kind of solution: https://forum.xda-developers.com/huawei-p9lite/how-to/guide-increase-headset-volume-t3624236/
but is for the 2016 model and european version, for me is not working.
maybe the directory is different, i hope can someone help me, cheers!

I have attached pictures of my Viper4Arise installation which works on my PRA-LX2 on B160.
Don't forget to get into the Viper4Arise Settings>Developer>Disable SElinux or else it would'nt work.
You can search in the Viper thread for the version I have. Sorry, I forgot how exactly I've been able to make this work, but it should once you have the right version installed.

Yes, SELinux permissive, install drivers, reboot. Each reboot you need to toggle SELinux permissive or it won't work.
Busybox by JRummy.
Root, of course.
The rest are all in a thread somewhere in the P8 Lite 2017, as it seems this forums of ours are stuck with B160, TWRP, Root, Busybox, Viper4Arise and recovering from semi-brick.
Unless we get EMUI 5.1 and Android O, or maybe even some custom ROMs (need sources), I think we have everything covered already.

Flash magisk v13.2 and install VIper4Android magiak module, after that push v4a 2.5.0.5 apk to /system/app/

Yes, you need it to be on /system.
Also, didn't know Magisk has a module for V4A, but nevertheless, it works fine on mine without it.

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..

Viper4Android on Pixel 4A 5G

Has anyone been able to get Viper4Android working an Android 11? i flashed using the April 2021 Factory Image and have tried following multiple threads and guides, but have never gotten V4A to work consistently/completely.

Viper4android Android 11??
There is viper4android for android11 or I need to wait?
forum.xda-developers.com
This is the Viper4Android I've used for 6+ months. Its the only working, plug and play version I've found for Android 11. You simply download the zip, flash in magisk -- and done. There's nothing else you need to do.
Its 100% safe. Its 100% working. So easy.
I can vouch for it... And love it!

Click on the youtube link, and the zip is in the info there. No need to watch the video. Just flash with magisk or a kernel manager... and done.

I'm on LineageOS for microG 18.1, Proton kernel 1.4, Magisk rooted and this is not working for me. Further more, it mess up with SElinux making it disabled. Fortunatelly, there is an app SElinux switch, that on every boot make it Enforcing again.

I have the 5a but there are no posts yet.....
are any of you getting V4a to work using the USB port ? I run my phone usually into a dac via the usb, but Viper's only working on my phone through the headphone jack.

That YouTube video has been removed. Any chance someone could post the .zip? TIA

Root with magisk and install the Viper plugin, works like a charm on my 4a 5G. Not much else to it.

Not as simple as that for me I'm afraid. Magisk module causes bootloop.
Had the ViperFX_Android11.zip before from that same YT vid (purple/white GUI) and it worked well.
No luck or erratic performance with other versions (black/green GUI), the one from the guy with the name that looks Thai -- Pittanddwwitt idk lol.

Are you rooted normally with magisk per the instructions in this forum? Thats all I've done. Do you have a phone from google or from a carrier?
I got mine from google. Im rooted per the normal instructions. I have magisk v2.7.2.1 and the magiskhide props config modules installed. Ive never had a bootloop with either.
Not really sure what else to try. For what its worth, I cant get viper working on a rooted pixel 3, no bootloops, but the status always says abnormal.

Bought from a 3rd party actually, sealed box, no carrier branding or firmware.
Magisk version (from Canary channel) is f822ca5b (23001) -- that doesn't look right lol... oh, and Systemless hosts module installed only.
I only lost Viper when I updated to the September factory image
<shrug> idk why </shrug->
don't think it happened with other updates.
I'm pretty sure tho that I'd be in top shape, also indebted, if someone could post ViperFX_Android11.zip since the above referenced YouTube vid is gone and, with it, the link and I can't find the same version anywhere else. Thank you very much.

I just received my used 4a 5g. Got V4A v2.7.2.1 downloaded from Magisk v23 working last night...but it was a long trial & error ordeal. First download it showed Unsupported and Abnormal. Thought maybe it needed the Audio Mod Library but that didn't work. Then I tried the Audio Compatibility Patch to no avail. I tried V4A Legacy. Mulitple installs and uninstalls of all the various modules and combinations. At this point I'm not even sure what I did, or in what order/combination, but V4A is installed and working as intended. I do NOT have any of the Audio modules installed, just V4A. Don't know why it didn't work originally, or what made it finally work after fiddling with it for about an hour, but for me, that's my story/advice. Wish I could give an exact process to follow.

Thanks for posting this! The version I had (v2.7.2.1) didn't work as reliably as it should. Often times it wasn't "processing". I uninstalled it and installed yours. So far it seems to be working well.
BIG BONUS - your version allows to view settings for the speaker, ear-buds, & blue-tooth without actually being connected to said devices. I never liked that "feature" of the newer V4A versions.

what about android 13?

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
