Huge thanks to [MENTION=8792089]1dopewrx05[/MENTION] I have V4A working on androidQ rooted stock OTA using the file from the labs download.

One question though... I'm used to the 'legacy' version which has the ability to save Profiles. I do not see this option with V4A 2.7.1.0, am I missing a setting? I had 3 different BT profiles for 2 cars and a pair of earbuds, is there anyway to unlock profiles on this version? Thanks.

Pixel 2xl, have you any suggestions?It could be useful to install factory images without deleting apps?
[Google Pixel 2 XL Questions & Answers] Badger50:
It's definitely worth a try. And, yes you can fastboot factory images without wiping any data or apps. Only other thing I can think of is, have you ever gotten the notification to allow certain apps to be installed from source, and then allow it?
[Google Pixel 2 XL Questions & Answers] failax:
I don't remember to have seen that advice for magix installation modules or apps.
[Google Pixel 2 XL Questions & Answers] Badger50:
You usually only get it when trying to install an apk. Something must be a little wonky with your permissions is all I can guess. Might have to factory reset or try fastbooting the factory image to rectify it unless someone else has a better idea :good:
[Google Pixel 2 XL Questions & Answers] KHANrad_SIN:
Yeah so with 2.7.1 you know how on the bottom there are 4 icons for headset, speaker, bluetooth and USB? If you tap any of those icons twice it will bring up a menu for that audio source. From there you can create a new preset or modify old ones by tapping on them if they are present.
[Google Pixel 2 XL Questions & Answers] bigwavedave25:
Awesome, thank you! I was not aware of that trick... too stuck in my old ways :eek:

Someone has managed to flash a factory image of Android 10 to Android 10?I tried yesterday with flash all.bat (deleting characters -w) and it stops at the middle before flashing zip image.
[Google Pixel 2 XL Questions & Answers] Badger50:
I've done it several times. Are you trying to flash A10 official over a Qbeta, or just flashing it again?
[Google Pixel 2 XL Questions & Answers] failax:
A10 official over A10 official.
[Google Pixel 2 XL Questions & Answers] Badger50:
Did you take an A10 ota first? If so, are your platform-tools and such are up to date?
[Google Pixel 2 XL Questions & Answers] failax:
Yes I tried A10 factory image over A10 ota zip.I've used the last platform tools.
[Google Pixel 2 XL Questions & Answers] Badger50:
And...you extracted all the necessary files from the factory image, and placed them all inside the platform-tools folder, and have tried different USB A to USB C cables sand ports? If your using a laptop, do you have enough internal storage?
[Google Pixel 2 XL Questions & Answers] Edgio60:
Legend. This worked perfectly for me!
[Google Pixel 2 XL Questions & Answers] failax:
Yes to all, look at the failed messages

http://img18106.imagevenue.com/img.php?image=21690_IMG_20190911_190008_122_957lo.jpg

EDIT..Solved!
[Google Pixel 2 XL Questions & Answers] Badger50:
Looks like a communication error of some sort.

Is this your first time using fastboot for factory images?

You may try putting your platform tools folder on your desktop, right click the flash-all.bat file, and select it to run as administrator. Can you please post a pic of your platform-tools folder contents.
[Google Pixel 2 XL Questions & Answers] failax:
I solved creating a new folder with essential files, in the previous folder there was something more..

Now I try to solve Viper installation problem..
[Google Pixel 2 XL Questions & Answers] failax:
Nothing to do even after installing factory image.It says if i want to update the existing app or don't install the app.
[Google Pixel 2 XL Questions & Answers] failax:
Finally after a factory reset, I managed to install Viper apk and drivers as described in the guide.
[Google Pixel 2 XL Questions & Answers] federalitamale:
So I've been able to successfully install the driver on both the 2.7.0 & 2.7.1 apks using 1dopewrx05's advice. Thanks!

However, I'm getting hung up on the driver won't enable / not processing after I turn on the master limiter and my eq selections. Wondering if anyone else is having this issue?

If I have music currently running - it even does that little blip of interrupting the music when I open V4A like I'm used to in previous versions; where the driver is loading and about to enable. However there is no affect on the audio - and the Driver Status displays as not enabled/not processing. Anyone else getting hung up at this step? Thanks for any advice!

Sailfish 10 (QP1A.190711.020) [OTA upgrade from 9]

V4A 2.7.0 (currently)

MAGISK 19.3 [*I did notice AML is currently 2.4; whereas I had seen it as 2.8 earlier?]

Playing from Google Play Music (if that possibly made any difference)

Thanks all!
[Google Pixel 2 XL Questions & Answers] poncespr:
You, my good sir, are my hero.

Thanks for this.
[Google Pixel 2 XL Questions & Answers] oranget:
Confirmed working..thank you!!
[Google Pixel 2 XL Questions & Answers] matusala:
I installed v4a and AML like in that post. Driver installs but does not work.

Fresh install of Android 10 on OG Pixel Sailfish

here is what it says

[Google Pixel 2 XL Questions & Answers] federalitamale:
Same Issue

My exact issue as well.

Though I had done an OTA update to Sailfish 10; so I was still holding out that a fresh factory flash might solve the problem. But appears it did not resolve it in your case, at least.
[Google Pixel 2 XL Questions & Answers] Koskee:
Pixel 2. Locked and loaded :cool:

I was getting so irritated that I couldn't get it working after trying probably at least 6 times using older procedure(s). Thanks for the tip!

Ah... my sanity, how I missed thee.
[Google Pixel 2 XL Questions & Answers] VladSoo:
Thank you all guys!

Also not from the first try, but it's work!

And I'm also install AML mode )
[Google Pixel 2 XL Questions & Answers] pa.pn2:
Even if Viper is enabled for me i see no differences for example in the Equalizer.

Any setting i do i don't notice any change.

Anyone else?

Thanks, but i am interested, are you on Android 10?
[Google Pixel 2 XL Questions & Answers] deebray36:
yes updated to android 10
[Google Pixel 2 XL Questions & Answers] 1dopewrx05:
Wow, so great I was able to help this many people out getting V4A up and running, I would have posted a tutorial thread much earlier had I known this was that big of an issue for this many people. As for the ones that are getting it installed but it is not processing, that is an issue I haven't run into personally so I don't have a direct solution, but what version of magisk are you guys running?
[Google Pixel 2 XL Questions & Answers] beejkitsune:
Can confirm this works for me.

Pixel 3 XL, Android 10 QP1A.190711.020, Magisk Canary 19.5 (19403), ElementalX-P3-2.05 (otherwise stock).

I did have to do the additions step of re-activating AML and installing the V4A driver a third time.
[Google Pixel 2 XL Questions & Answers] poboy92:
+1 on the 3rd try. I did not go back into Magisk and re-disable audio modification library. Is that needed?
[Google Pixel 2 XL Questions & Answers] 1dopewrx05:
It is completely random if this step is needed or not. That's why I included it in my tutorial. For me personally, that step is not needed but on my back up Pixel 2 XL I do need to do that step so my advice to you is if it's not working without that step then I would start fresh and remove both viper and AML and start from the beginning with the addition of that last optional step this time and it really should work. I haven't met a single person yet that meets the requirements and this tutorial doesn't work for. If it's not working, there is a very high chance that something was either done slightly different then I outlined or you just need to tack on that last step. Good luck buddy :good:
[Google Pixel 2 XL Questions & Answers] sandiprickyroy:
I've got the solution to install it very peacefully... Magisk is no more needed.

But for some unknown reasons it's not working sometimes... I'm working on it... once I find the best solution I'll post a youtube video and will share the same with you.
[Google Pixel 2 XL Questions & Answers] ThaWaX:
Works like a charm, thank you very much! :)
[Google Pixel 2 XL Questions & Answers] long45343:
why when I reboot,I drop into fastboot
[Google Pixel 2 XL Questions & Answers] Stogie87:
Same here. Only solution to get out of download mode is to reflash viper via twrp. Even if I get an error message, system boots after this fine again.

I am on LOS 17 for tab s3.
[Google Pixel 2 XL Questions & Answers] patster98:
My op3 just keeps rebooting into fastboot mode after installing driver (happens with and without AML).. any ideas?
[Google Pixel 2 XL Questions & Answers] pekkle_hksar:
me too, only could boot into fastboot...

need to boot to twrp, delete /data/adb/modules/viper to boot normally again.
[Google Pixel 2 XL Questions & Answers] gr4ffitiktime8@gmail.com:
Worked perfectly! Although I still had to re-enable AML in order or it to work, it sticks through reboots, and it works!
[Google Pixel 2 XL Questions & Answers] GohanBurner:
Literally going to send my PIxel 4 XL straight back if I can't Viper working on 10. So far no luck.

What I did:

Downloaded APK from labs

---make sure the app has permissions to use your storage, mine didn't by default

Install driver

Reboot

Install AML

Reboot

That did it for me on stock Android 10 OCT update.
[Google Pixel 2 XL Questions & Answers] MRmister1125:
same issue :/
[Google Pixel 2 XL Questions & Answers] 1dopewrx05:
Honestly, I would have no idea about that because I've never had or used an op3. If it was a Pixel device, I could more than like get you through it. Sorry man
[Google Pixel 2 XL Questions & Answers] patster98:
Thanks anyway man! Very nice of you.. is there anything you believe i could try anyway?
[Google Pixel 2 XL Questions & Answers] 1dopewrx05:
My honest opinion is going to seem like a buzzkill but I'm pretty positive that it's your software/hardware combo. To clarify, I believe viper hasn't been optimized to run with an older OnePlus with the newest OS. That can make things tricky for developers and crappy for consumers/users. My one and only possible solution would be to downgrade to pie but obviously that would have to be worth it to you, giving up Q just to have viper.
[Google Pixel 2 XL Questions & Answers] pratyush28:
Even im on op3T, ColtOs Q could you please let me know if you somehow get viper to work? I tried the legacy version but it made my phone boot to bootloader just like you said earlier.
[Google Pixel 2 XL Questions & Answers] Alexisnotfrommars:
For those if you who didn't know viper for Android needs to install the driver then create a magisk module it requires 2 reboots you also need to enable "Attach audio effects" found in the settings

Currently only version 2.7.1.0 works with Android 10
[Google Pixel 2 XL Questions & Answers] grandpajiver:
Sorry to cross-contaminate, I'm using a OnePlus 7t, there is no TWRP for it yet, and after flashing the 2.7.1.0 module, I got caught in a bootloop as well. Didn't open it after flashing, didn't grant it storage permissions or root, didn't give it a chance to update drivers, just flashed and rebooted.

Stuck at bootloader. I had to completely start over from scratch (as in fastboot flash all my images, as I'm using a prior version's patched boot.img for Magisk, and my images were from a previous version).

Need some TWRP goodness (I know the primary developer just had a 4th kid, may be a while)... so Pixel 4's and 7t's are stuck for now... and I'm not touching this until TWRP is available to modify Magisk in case things go awry. Maybe this is an A/B flashing issue? *shrug*.

Anyways, you're not alone. I miss V4A, this comes with dolby atmos.... but it doesn't allow me to utilize my profiles for the right situation.
[Google Pixel 2 XL Questions & Answers] GohanBurner:
The 7T comes with Dolby Atmos (or whatever), so you'd probably have to disable anything that has to do with that before attempting to get V4A to work. Maybe use Titanium Backup and uninstall/freeze anything having to do with atmos. Not to mention, OxygenOS has so many customizations that I would actually be surprised if the steps that work for a completely stock android experience work.
[Google Pixel 2 XL Questions & Answers] grandpajiver:
Yeah.. sorta makes sense. OOS doesn't deviate too much from AOSP, but yeah. V4A worked in rooted OOS stock pie and that had Dirac preinstalled...V4A detected an incompatible sounds good then, aml too care of that. This time, it didn't notice an incompatible module.

Of course, this is the wild West of Android 10 modification, and patience is a virtue ?. Still gonna wait for TWRP.
[Google Pixel 2 XL Questions & Answers] billouetaudrey:
The issue is the V4a module, happy to have orangefox for disable, or phone die :D

Bluetooth headphones for v4a Android 10

Have you tried with Bluetooth headphones yet? Mine seems not to be working even though it says enabled

Does viper works with bluetooth devices ? Can u try and report back if possible ?:o
[Google Pixel 2 XL Questions & Answers] DroidIt!:
On OnePlus 7 Pro ? but played with settings today and definitely works with my car bt.
[Google Pixel 2 XL Questions & Answers] Pete02:
+1.... I have Viper installed on a Pixel 2 and Pixel 3 and both sound great in the cars via bt.
[Google Pixel 2 XL Questions & Answers] 1dopewrx05:
Yes, it works with all outputs that V4A has options for. Bluetooth, USB-C port and speakers
[Google Pixel 2 XL Questions & Answers] aznpiggy:
works fine with my samsung galaxy buds
[Google Pixel 2 XL Questions & Answers] Pete02:
Hi guys, I know I reported earlier that Viper works via bt in my car and it does. Sounds awesome. However today I tried to connect to the car via usb for Android Auto (it also stays connected via bt for some reason) and Viper doesn't seem to detect Pandora. Once I disconnect Android Auto and just connect via bt Pandora and Viper work great. Is there some kinda work around to get Viper to recognize Android Auto?

Edit: nvm.. I've tried everything but I think it's the Android Auto app itself. When active it cancels out my dark theme so I think it's got bugs. I'll check it again next time it updates.
[Google Pixel 2 XL Questions & Answers] Soulflyerr:
Rootless

Guys, good morning (at least here hehe)!

I use Viper for long time, always with root. But today i saw in Zackptg site's that exists a rootless option. Just need to install, download zip drivers and done. But i can't find where to put this zip and app keeps trying to find root.

Thanks in advance and sorry my bad english.
[Google Pixel 2 XL Questions & Answers] Strephon Alkhalikoi:
The version of V4A you may be referring to - and the one I use - doesn't require a zip. It uses Magisk installer tech to install drivers into /sbin and then reboots.

On Android 10 it does work, but the installer occasionally fails to install the driver the first time. Rebooting and retrying seems to work however.
[Google Pixel 2 XL Questions & Answers] Soulflyerr:
Ah ok, thanks for replying.
[Google Pixel 2 XL Questions & Answers] QHUYFOTO:
following your tutorial . after install driver at viper app . it auto reboot and then bootloop :((( like normal installation step . plz . thanks for your help
[Google Pixel 2 XL Questions & Answers] 1dopewrx05:
What are your details? Is it a Pixel 2 XL? Which Android version are you running? Also which version of V4A are you attempting to install? Try to provide as much detail as possible as I've never heard of inducing a bootloop just from V4A's driver, at least not on a Pixel 2 XL.
[Google Pixel 2 XL Questions & Answers] QHUYFOTO:
thank you for your help . my phone is mi mix2s . running custom pixel3rom . at android 10 QD1A.190821.01

i installed latest v4a . i did everything but it not work
[Google Pixel 2 XL Questions & Answers] charackthe:
I clean flashed my ROM and Viper still says that it is installed in 2.6 app and when I click 'uninstall driver' it takes its time and nothing happens just a purple circle spinning endlessly. I have no idea how to remove Viper4Android now. (I had flashed the rootless viper4android zip on the website so it installed directly to the system files I guess? Even after wiping system vendor data caches it is still installed.) Now I need help to figure out how to remove this thing.
[Google Pixel 2 XL Questions & Answers] 1dopewrx05:
That's very strange that after wiping your complete phone viper is still persisting. Get a root file manager (I use root explorer) and go to /data/ADB/Modules and viper should be there if it's installed and you can delete the viper folder to force-remove it. This is assuming you have magisk installed. Let me know how this goes.

---------- Post added at 07:50 PM ---------- Previous post was at 07:46 PM ----------

I understand. This is the issue, my method outlined in this thread only guarantees success on the pixel line of phones. All other models use different processes and may even be incompatible with viper all together. I apologize but I know nothing about xiaomi phones or how to get v4a running on them.
[Google Pixel 2 XL Questions & Answers] charackthe:
I had installed the non-magisk version accidentally. And currently I'm in this mess lol. That directory has no Viper inside.
[Google Pixel 2 XL Questions & Answers] 1dopewrx05:
If you don't have the capability yourself, you can pm me the v4a you installed and I will decompile it and be able to tell you where it all installed to. You can host on Google drive and pm me the link or just send me the link to the exact version and build you installed.
[Google Pixel 2 XL Questions & Answers] 1dopewrx05:
First try going to /data/app and find v4a there and delete it (it'll be the package name, not just viper4android.) Check my screenshot for an example, this is my v4a listed in /data/app
[Google Pixel 2 XL Questions & Answers] charackthe:
I had installed the Zackptg5's Rootless Driver Installer. I believe that is the culprit. Because only other Viper I have tried was Magisk version and I removed that a long time ago (and even removed magisk)
[Google Pixel 2 XL Questions & Answers] jurko217:
Viper4android works flawlessly in PE 10 and Havoc 3.0 for me with AML and audio compatibility patch.

What i do if No driver installed after reboot ?

Uninstall Viper4android apk and reinstall module again.
[Google Pixel 2 XL Questions & Answers] Cichy26:
Maybe anybody will work with my method.

Android 10 xiaomi.eu mi max 3.

Install from magisk v4a reboot(don't install drivers)

Install selinux permission and set on permissive reboot

Install from magisk aml and reboot

Go to app v4a install drivers and reboot

When rebooting phone go to fastboot you must reboot it with recovery go to data/adb/modules/v4a

Change name post-fs-data.sh to post-fs-data.bak and reboot to system.

Go to app and Enjoy v4a ?
[Google Pixel 2 XL Questions & Answers] blu3sn0w:
Thank you!! I have a Mi5 on Pixel Experience (Q) and I can confirm that your method fixes the fastboot forced boot and loads all the drivers correctly!
[Google Pixel 2 XL Questions & Answers] everesee:
I can confirm that works, thank you so much!
[Google Pixel 2 XL Questions & Answers] krolla03:
I got it to work using this method. Had to do the extra last step to get it to work.

Forgive me but this is the first time using Viper probably since it was included in a man im gonna say a ICS build on my LG G2X lol.

My question is. After i enable a few settings do i have to reset for them to take effect? because just toggling effects on and off i cant hear a difference at all.

(currently messing with the headphone settings.)

Nevermind. It looks like (from my research) you need the "Master Limiter" enabled for any of the other effects to work?!?!?!
[Google Pixel 2 XL Questions & Answers] krolla03:
Hmm. While im sure Viper can make audio sound better. (i messed around with a few of the headphone settings and did get better audio)

Then i went to the car (Bluetooth and a stock 8 speaker Infinity system) I messed with a few of the settings and really all i could get it to do was make the vocals sound less loud while all the instrumentals sounded the exact same.

I might not have the right settings nor do i really know what they all do or understand what they all do.

I wonder should i set the cars EQ and settings to all flat before messing with Viper settings.
[Google Pixel 2 XL Questions & Answers] 1dopewrx05:
Yes you need master limiter enabled on any of the profiles for them to work. Master limiter is in the sense of those viper settings, so that's like the master power switch of viper and you can instantly turn all of your chosen audio settings on or off just by switching the master switch on or off.
[Google Pixel 2 XL Questions & Answers] Strephon Alkhalikoi:
I use Audiophile X for Viper and it seems to work well in most situations. About your car, your car's EQ should be set to flat, as having the sound equalized twice makes music sound really bad. The end result is the sound being distorted by the double equalization.
[Google Pixel 2 XL Questions & Answers] krolla03:
What is audiophile x?
[Google Pixel 2 XL Questions & Answers] Strephon Alkhalikoi:
Audiophile X is a set of custom profiles for Viper4Android. If interested, there should be a thread about it on the forum.

Working like a charm in Evolution x 3.5. thank you :D
[Google Pixel 2 XL Questions & Answers] JoxeeM:
worked perfectly! :D
[Google Pixel 2 XL Questions & Answers] Madjax2020:
Only issue is, it always takes a few reboots to know if viper is working. Only way to make sure viper is working is open it up? But by then the steps you say can't be done. UNLESS once it reboots disable the mod check viper and if it asks to install drivers ... Don't make sure mod is enabled THEN reboot and try the process??? Make sense in my head.
[Google Pixel 2 XL Questions & Answers] Badger50:
Is this a question, or just a statement?:confused:

If it's a question, then I assure you that if you follow the instructions to the letter, it will work at the end :good:
[Google Pixel 2 XL Questions & Answers] Madjax2020:
I tried but it takes up to 3 reboots for the drivers to stick, so what do you do then?
[Google Pixel 2 XL Questions & Answers] Lughnasadh:
If you follow those directions just as they are written it will work :good:
[Google Pixel 2 XL Questions & Answers] Badger50:
Well, if it sticks, then mission accomplished :good:
