Viper4Android Hanging

(Unlocked Model, Unlocked, S-Off, Verizon RUU, rooted)
I have tried installing V4A, but after installing drivers it hangs upon opening, eventually causing the phone to reboot.
I have tried both backing up and renaming the htc_audio_effects.conf file, as well as editing it to include the V4A info. Nothing seems to work.
Any ideas?

First of all you need root. You have to set Android to permissive, then install V4A using TWRP and ZIP. Install drivbers and it will work AFTER you set V4A driver mode to "compatible". Just tested using latest Leedroid custom rom (nightly R34) on HTC 10 (s-off).

What version did you use? I'm using Venom and I've done exactly what you did and Viper keeps prompting me to install the driver

Flash in recovery. Spent all afternoon looking for proper install instructions and found nothing until that nice fellow posted those.

Viper4android did not work 100% using Leedroid: systemsound got crippled
Viper4android is working 100% with ViperROM. Just flash the above ZIP and all is working fine.

I'm on Leedroid 1.2 stable and works perfectly.
I did experience the crippled audio you're referring to during a failed installation. Make sure the /system/etc/htc_audio_effects.conf exists and wasn't deleted.

Which specific version did you flash? What changes did you make to get the best audio out of the 10?

Do you have any idea whether it would work on stock rom or not? Of course I'm rooted and s-off.

Check your selinux status it needs to be permissive for V4A to work.

Actually I installed it and it works. Kinda. And yes I used a script to get permissive selinux. It only works with music, (spotify, google music). Youtube has no sound whatsoever ar audible is crackling and fussing all over. "Fixed" it by changing the htcaudioeffect file back to normal, which disables viper4android. I just wish it worked with all sound.

First off I will say I am on Stock Rooted ROM and it works perfectly, I have confirmed its 100% compatible, You DO NOT have to use permissive, I have an Enforcing Patch in my thread along with more info on what you need to do to get it working, also for HTC 10 there is a specific file to flash that I also made, without it V4A will not work, and keep asking to install drivers!
My Thread
V4A HTC 10 Fix
After this, if you can't get it working either there is something you still haven't done or your ROM developer has messed up a certain system file associated with Audio, I have seen this before.
One last thing I should note, S-ON can cause issues, you should either have S-OFF or System Write Protection Disabled via a kernel module, S-ON can prevent a script from making changes to /System.

About V4A
On the A9 it will work but it will put Boomsound to Off all the time, is it the same on the 10 or you can use both without problem?

I use both no problem, personal Profile and V4A works great, Dolby Headphone effect works perfectly as well.

I installed the 2 zips a couple of days ago and the sound is pretty great for me. I see people mentioning different profiles, enabling speaker and other modes, etc., but how can you do that without installing the APK (as advised not to)? I don't know of any other UI to control those types of things?

Viper4Android & Other Audio Mods

Hi
I was wondering if other OP3 Owners tried installing audio mods such as Viper4Android and MaxxAudio?
I faced bugs with Viper4Android, SE was on permissive but it wasnt processing audio.

Look into how to remove the deep buffer from audiopolicy.
Then v4a should work fine.
I don't have my device yet so can't confirm but this is usually all that is needed

Can we uninstall XtremeMusic AudioFX without it messing up V4A? Dont really want another app thats not being used on my app drawer.

I'll be making a flashable zip once I get the device which will allow you to run viper with enforcing se policy mode.
Can anyone link to this viperfix apk.
Does it simply modify the audio policy?

There is no need of all these things. Just flash the DivineBeats zip and you're good to go.
Tested and working fine.

Yeah, unlocked bootloader, custom recovery and root are required for pretty much any modifications. Can't modify system files without root, can't flash ZIPs without custom recovery, can't get custom recovery without unlocked bootloader.
Also it's advised to make a nandroid backup before you start messing with the device which again requires stuff mentioned above.
If you're not yet rooted, there's a good guide on this forum; just follow it by the letter and everything will be fine. Just a heads-up: unlocking bootloader will wipe your device (factory reset) so be prepared to spend some time setting it up again ...

I think it's important to link the source.

I'm not sure if I want to root or not, but if I do it definitely wouldn't be until some of the ROMs start supporting Dash charge.

ATTENTION!
Flashing "DivineBeats" is not as simple and safe as Edios suggests.
On my device, I get a bootloop, i.e. the device boots up to the launcher, I can do something for a few seconds, then the device reboots.
Same thing as when I flashed Viper4Android.
Perhaps it's just an incompatibility with Xposed, who knows; but for now, these sound mods are unfortunately not usable by me...

same question here: is this CM or OxygenOS? I tried divinebeats in oxygen and as reported, i get a bootloop. Will have to assume this will result in a bootloop on Oxygen too.

For me I noticed I have to reboot when I install each and every module. On my oneplus-5t I could install a bunch and then reboot once but on the pixel presumably due to the new firmware, you have to reboot after each module is installed and this definitely helped me.

I don't think its a module specific compatibility issue. Every single module I try to install seems to install fine but just doesn't show up in the list of modules. I've tried a lot of different ones.

Interesting. That's kinda weird because I've seen many users running them on the DP's. Does clearing magisk manager app cache/data help at all? And I'm sure you've granted storage permissions as well.

Yep, tried that and also installing through manually patching boot image, flashing through TWRP and installing through direct installation through magisk manager. Sometimes the installation fails and on reboot it'll say it's installed but safetynet will fail. Even when it installs fine modules never work though. Module downloading is all fine, during installation it goes ahead just fine as well but the modules just don't show up in the list after installation/reboot.

Don't know what to tell you my friend. Grab some install logs and head over to the magisk forums for some additional help is all I can suggest. I wish you luck :good:

I'm trying to figure out where i went wrong, because the last time i tried ROOTing PDP3, i couldnt boot and i am yet to see and PDP3 Patched_Boot.img or TWRP Recovery...
I did the following:
-Fastboot Flash-ALL PDP3
-Boot and set-up device PIN
-Boot into Fastboot
-Fastboot boot TWRP3212.img
-Use TWRP Installer to install Custom Recovery on device
-Reboot Recovery
-Flash Magisk v16.4
-REBOOT SYSTEM
-I think i ended up Looping @ G

Anyone get Viper4Android to Work on Q?

Before I go back to 9.0.0, i figured i would ask....
Anyone get Viper4Android to install properly on Q?
I tried the latest Viper Magisk Module v1.4.2 i think... Magisk completed the installation but after reboot, Viper is requiring Drivers to be installed. So i install the Drivers, which took longer then normal, reboot and BAM! Viper needs to install Drivers on your device.
So Q doesnt seem to wanna play well with the Viper drivers.
And i tried installing Busybox for ****s and giggles and install fails in Magisk....
Thanks in advance for any assistance and/or **** head comments,
T

Try using this viper apk, it generates a magisk module when you reboot the phone. In the latest update post, OP says:
The compatibility mode switch has been added back. This seems to be mandatory for car mode and some android q builds.

Question Viper4android on any android 12 custom rom

i've been trying for 2 whole days now to install viper4android on my oneplus 9 pro, i just can't get it to install. I'm basically stuck in an install loop and i've tried almost everything (permissive, AML, clean install, v4a repackaged, android 12 fix) but none of them work.
I wonder if anyone got viper working on their device running a custom android 12 rom

Take a look:

Hi guys i used V4A on all of my 1+ devices. Started from the 1+1, 5, 7Pro and now i own the 9 Pro. The phone is rooted with a patched img, Magisk 24.3 installed, stock recovery. OOS Version is 11.12.10.10 Somehow i cant get V4A get to work...

tried that too and just now tried it on just stock lineage os on A11 but still no luck nstalling v4a

This method worked for me in several custom ROMs in A12 and A12, bit just following the steps exactly and rebooting in every step (and you have to activate legacy mode).

i did follow every step with the reboots after each module but i'm still stuck in an install loop so i cant even get to the settings unfortunately... i've never had so much trouble with a device

Uninstall all the modules, try the procedure again with these files. I tried with other and got driver loop as you did, but it worked with these.

So install magisk, reboot, AML, reboot, JamesDSP, reboot, V4A, install drivers and let it reboot? kernel can stay in enforcing?

After last reboot, you have to substitute the fs file as stated in the other thread, reboot again and set legacy mode.
I am in enforced kernel, yes.

You have to replace this file in /data/adb/modules/Viper4AndroidFX and reboot. About JamesDSP I don't really use it so I disabled the app, although I have to do it in every reboot
