Reminder about the latest POSP build

"It is HIGHLY recommended that you MUST flash MIUI fastboot fw before flashing this build"

Not doing so has lead to ppl getting hard bricks, including me.

So make sure to back up your data, flash 12.5 twrp then get a twrp 12.5 compatible recovery and THEN flash posp.

If you're unsure about something check https://t.me/dreamsupportbegonia for begonia specific help or https://telegram.me/SaucyPotatoesOfficial for posp.

@ Ryan Cr 7

I've followed all of your steps but still no driver installation. (CR Droid, Oneplus 8 pro)
[Android Apps and Games] RyanCr7:
In one plus phones you need to change your seLinux mode to permissive first and then install viper4android.
[Android Apps and Games] ichbinsauch:
OK, Thanks .
[Android Apps and Games] topat:
thank you very much it worked perfectly
[Android Apps and Games] drewman521:
I'm SOOOOOO CLOSE to getting it working. Followed your instructions to the letter, and I get everything looking good in the driver status EXCEPT for PROCESSING. It's still a no and that's with tweaking compatibility and legacy. Any final tips?? Thanks.
[Android Apps and Games] lawrence_craig:
Can confirm this works on the OnePlus 8 Pro running Android 11, on the xxx no limits magisk module. Thanks so much.
[Android Apps and Games] drewman521:
Never mind... I got it....
[Android Apps and Games] RyanCr7:
For some phones you need to change SeLinux to permissive to get V4A to work.

But changing seLinux to permissive is unhealthy for your phone cause it might open backdoor for some apps to take advantage of your root access.

I am updating the app and magisk now. Come back here 30 minutes later and see if the new solution works.

Play a song in your device music player.

Then open Viper4Android app, Go to that CPU lookalike icon on the top right, it will show you the driver status.

Take a screenshot and share it here.

Don't forget to keep the music player running while taking the screenshot.

Not working on OnePlus 7t Pro on Oxygen OS 11 Beta 2, set selinux to permissive, and followed all steps... Any suggestions?
[Android Apps and Games] RyanCr7:
Have you tried the second apk and magisk?

Is one plus 7t pro and 7 pro similar?

Cause a few days ago I've set up Viper using this method on 7 pro A11 OOS beta.
[Android Apps and Games] L4WL13T:
Just gave it a go, and still no luck :(

I'm not too sure on the differences between the two devices, though I wouldn't imagine they'd be vast. Once OOS11 comes out of beta I intend on doing a clean install, so perhaps then is the time to give this another shot.
[Android Apps and Games] RyanCr7:
Sorry it didn't work. Does your rom comes with a pre-installed equalizer/sound system like Dolby?
[Android Apps and Games] Techguy777:
You guys should just flash the magisk viper 2.7.2 module it usually works and if it doesn't flash the other sound mods and audio sound mod lib. I found that trick back in oreo. However the samsung oneui devices are the hardest because they only come with enforcing kernel unless a dev makes a permissive kernel. I prefer 2.3.4 with the super driver but you have to have a permissive kernel on samsung. You also need to have busybox installed in magisk. With android 11 one ui 3.1 on samsung you need to use legacy mode again unless you have a permissive kernel than just busybox and viper 4.4 module installed with 2.3.4 as a user app that's my favorite. Right now I'm stuck on 2.7.2 because no permissive kernel for oneui 3.1 yet
[Android Apps and Games] kunver400:
Perfect, thanks for sharing.
[Android Apps and Games] dorimanx:
Yes solution for you is to change the file of the post fs and in line with the mount -o set the Second path to your path, so needed sounds effects will be what viper needs.
[Android Apps and Games] Leeum:
Sadly couldn't manage to get it to work on my S22U on OneUI 4.1 and sadly the main reason i root is for V4FX
[Android Apps and Games] goila:
I did that at first but didn't help
[Android Apps and Games] ecera:
Hi, on the Oneplus 10 pro, myself and I think anyone who's tried installing viper has been unsuccessful. The fix in the post-fs-data.sh for the Oneplus 9 pro and im sure other devices involves binding the audio_effects.xml under vendor/etc and odm/etc. On the Oneplus 10 pro the audio_effects.xml exists under odm/etc as well as in 3 other locations (please see attached picture). Would we have to bind all these locations? Or what would you recommend? Thanks.
[Android Apps and Games] dorimanx:
Yes you can try that, add more lines of mount -o with second path as the location of audio_effects.

[Android Apps and Games] zgfg:
Thanks for the hints.

Finally I made V4A working on my Xiaomi 11 Lite 5G NE, stock MIUI 12.5.8/Android 11

- I don't need AML since I don't use any other audio module

- Install and run the original VIPER4Android-FX.apk (FX 2.7.2.1).

It asks to install drivers and the phone reboots

- Upon rebooting, I copy the attached post-fs-data.sh to /data/adb/modules/VIPER4AndroidFX (over the existing post-fs-data.sh).

I had to modify your post-fs-data.sh and instead:

mount -o bind /vendor/etc/audio_effects.xml /odm/etc/audio_effects.xml

I put:

mount -o bind /vendor/etc/audio_effects.xml /vendor/etc/audio/sku_yupik/audio_effects.xml

Actually, I have two other subfolders on /vendor/etc/audio with audio_effects.xml, but left them commented-out in the attached post-fs-data.sh since I tested and found that I don't need to mount to them

- Reboot and then run again VIPER4Android-FX.apk, it doesn't ask for the drivers anymore.

I just change to Legacy mode (settings) and it shows Status = Normal, and it works then.

- I also didn't need to switch SELinux to Permissive mode (setenforce 0) as somebody suggested in another post

Obviously, the needed locations to mount the V4A audio_effects.xml will depend on the particular device.

One can search for the locations of audio_effects.xml by executing (add additional system paths if needed)

su
find /system -type f -name audio_effects.xml
find /vendor -type f -name audio_effects.xml
find /odm -type f -name audio_effects.xml

and then experiment with mounting to those commands by modifying the post-fs-data.sh

If VIPER4Android-FX.apk still asks for drivers, do not accept to reboot but change the mount command in post-fs-data.sh and try again

Always make sure that /data/adb/modules/VIPER4AndroidFX/system/vendor/etc contains audio_effects.xml, otherwise there will be no V4A audio_effects.xml to mount
[Android Apps and Games] silen3c:
What do I do if /data/adb/modules/VIPER4AndroidFX/system/vendor/etc does not contain audio_effects.xml? I also have 5G NE (Android 12) and I can't get it to work. My /vendor/etc/audio/sku_yupik/ path is the same.
[Android Apps and Games] aldohe1:
Doesn't work Samsung a12
[Android Apps and Games] zgfg:
Run the V4A apk, it will complain that driver is not installed, let it install and reboot.

After reboot you will have audio_effects.conf and audio_effects.xml in /data/adb/modules/VIPER4AndroidFX/system/vendor/etc

But if you installed Audio Modification Library then it merges conf and xml from all your audio modules.

Eg, I later added AML and JamesDSP, and now my /data/adb/modules/VIPER4AndroidFX/system/vendor/etc and /data/adb/modules/ainur_jamesdsp/system/vendor/etc have no conf and xml files, but AML merged them and merged files are in /data/adb/modules/aml/system/vendor/etc - attached is the screenshot of that xml, showing how both JamesDSP and V4A were merged there (and merged files are correctly mounted to /vendor/etc locations).

Both JamesDSP and V4A work - I can run them in parallel and hear when I enable/disable some mods in one or another
[Android Apps and Games] silen3c:
Yes, it always complains that driver is not installed.

I do not have anything in /data/adb/modules/VIPER4AndroidFX/system/vendor/etc after reboot.

I do have the /data/adb/modules/aml/system/vendor/etc folder but it is also empty.
[Android Apps and Games] silen3c:
Ok I have installed JamesDSP_Manager-v4_4__9_8_2021_-84.zip and now I have audio_effects.conf in /data/adb/modules/aml/system/etc and audio_effects.xml in /data/adb/modules/aml/system/vendor/etc/audio/sku_yupik

Viper4Android finally works. Huh :)
[Android Apps and Games] zgfg:
Install again, first V4A only as I did, without AML and other audio mods

Btw, mine Xiaomi 11 Lite 5G NE is MIUI 12.5.8, don't know about MIUI 13
[Android Apps and Games] ffp.:
Ok, I'm trying very hard to make V4A work in my S22 Ultra (rooted snapdragon) running Android 12, but I'm not getting anywhere.

I've tried everything I could find, including everything posted in this thread.

Tried another modules, like Aml, james dsp, all audio mods. In different install/reboot orders.

Also tried replacing the post-fs-data.sh file, with ones downloaded from internet snd one custom i made.

Here is my folder that has audio_effects .xml

Here is my data/adb/modules/V4A/system/...whatever folder:

I adapted the path to the ones that have audio_effecta.xml. Is that what I should do?

Anyway, didn't work. So, where sre V4A drivers installed, so I can see if they sre there?

Also, should i5do something else than editing the .sh file?

EDIT: @zgfg @dorimanx , would love to have your help.

How do I get DDC, profiles, and Kernel to work on OP6T running the latest LOS 19.1 nightly?

I have all the files saved in the correct location from previous installs, but they are not loading up.

Is there a new location beside "com. pittvandewitt....." folder?
[Android Apps and Games] zgfg:
Folder for V4A 2.7.2.1 on Internal memory:

/Android/data/com.pittvandewitt.viperfx/files

[Android Apps and Games] yoruuba2:
Thanks.

My Android/data folder does not have viper folder. It's actually empty

When I try to create a folder using MiXplorer, or move a folder from root it fails
[Android Apps and Games] zgfg:
/Android/data folder cannot be empty, tens and tens of apps keep the stuff there - in my case, over 120 system and user apps on one phone and over 130 on my other phone!!!

With ls command from Terminal

(or from File Manager in TWRP) you will see many subfolders there

Two of my screenshots below are also from MiXPlorer, but by using a build that can read /Android folder on Internal memory, on A11+ - there is a thread on XDA for MiXPlirer and that used to be debated there
[Android Apps and Games] Meisterchef:
God damn guys. Don't mess with selinux. What is that?

You don't need extra modules.

1. use any explorer with root and locate

/data/adb/modules/ViPER4AndroidFX/post-fs-data.sh

2. add this

magiskpolicy --live 'allow audioserver audioserver_tmpfs file { read write execute }'
magiskpolicy --live 'allow audioserver system_file file { execmod }'
magiskpolicy --live 'allow mediaserver mediaserver_tmpfs file { read write execute }'
magiskpolicy --live 'allow mediaserver system_file file { execmod }'
magiskpolicy --live 'allow audioserver unlabeled file { read write execute open getattr }'
magiskpolicy --live 'allow hal_audio_default hal_audio_default process { execmem }'
magiskpolicy --live 'allow hal_audio_default hal_audio_default_tmpfs file { execute }'
magiskpolicy --live 'allow hal_audio_default audio_data_file dir { search }'
magiskpolicy --live 'allow app app_data_file file { execute_no_trans }'
magiskpolicy --live 'allow mtk_hal_audio mtk_hal_audio_tmpfs file { execute }'

3. save and reboot. open v4a, toggle legacy mode and it should work. It worked for me on overbloated miui so it should work for you

Hey @dorimanx glad to read your name. Used your kernel for LG G2. How time passes :') Hope u doing good
[Android Apps and Games] yoruuba2:
For whatever reason that folder is empty 0kb. All my apps including banking are working fine.

V4A works but the only problem is setting up the profiles.

I guess at some point in time I will do a factory reset and start with a fresh install.
[Android Apps and Games] Meisterchef:
Mmh. If you use magisk it shouldn't be empty.

Yesterday I discovered an updated v4a with magiskpolicy etc etc included.

Maybe this could help somebody

Hi there,

I have been trying to get Viper working on my Oneplus 8 pro for some hours now but it keeps asking to install the drivers. Could you please clarify a bit on your guide? The part about adb shell issnt quite clear to me. I do have a root explorer app and offc my phone is rooted with magisk already. What file do I need to copy which folder?

Update:

Based on another post i was able to figure out which file needs to be copied to where (the post-fx file needs to overwrite the same file in data/adb/modules/ViPER4AndroidFX. Now the drivers are installed and with legacy mode on all driver checks are cleared :D

For me using this module everything works - https://github.com/programminghoch10/ViPER4AndroidRepackaged/releases

I am on android 12 (los 19) and other options resulted in driver loop.

You should remove all audio modules before and then try adding them back 1 by 1 if you have any. For me 'audio misc settings' conflicts with viper and get 'Driver not found', but I was only interested in that module for more audio steps increase anyways and found alternative way to get it.
[Android Apps and Games] Thecurse21:
I've many methods including using only the repacked version nothing works on the zenfone 9 I hope someone who owns the phone and has done it to share, but alas no luck
[Android Apps and Games] rocketda7331:
Did you try with other modules disabled? From your magisk screenshot I can see many audio modules. Perhaps you could even try installing viper only and no other modules for testing.

Mind sharing your solution step-by-step?

I tried something similar but no luck.....
[Android Apps and Games] dnb1987:
It has been a while since I got it working but ill try to explain how i got it working.

1) First make sure your phone is rooted.

2) install Viper as explained in this threat.

3) find the post which includes the post-fx file.

4) install a root explorer app.

5) overwrite the existing post-fx file located in

data/adb/modules/ViPER4AndroidFX.

6) reboot your phone and the drivers should be installed.

Since this is all from memory i cannot guarantee this will work in your case.
[Android Apps and Games] elmor0:
Thank you for replying.

I ried this & several other variations of this method including different post-fs-data.sh file options - Still no luck.

Each time I open v4a app, it says no drivers installed & prompts me to install them by pressing okay, once I hit okay then driver installation proceeds & phone restarts automatically - Same problem repeats once I open v4a app again......
[Android Apps and Games] dnb1987:
No problem and sorry to hear it didn't work. Just out of curiosity on what device are you trying to install viper and which version of Android are you running? It may also be related to which version of viper you're trying to install?

[Android Apps and Games] zgfg:
It's been discussed here. If your phone uses 64 bit audio drivers, V4A (drivers not updated for 3 or more years) cannot support that, dead end

Eg, if JamesDSP requires 'Huawei' option (forcing 64-bit drivers) to work properly, then that's your case
