It pains me to see many of you having an extremely frustrating experience striving for a complete ViPER|Audio™ installation, at the same time seeing others having no issues whatsoever. I know that makes it even more frustrating and I am devoted to providing you with the same painless installation experience. With 4.0 released and "done for now" I am beginning the compatibility phase, especially Samsung devices which seem to be the most temperamental.

ViPER|Atmos™ 4.0CT Beats™ Huawei™ Edition​

CT simply denotes Compatibility Test. This version removes all supolicy and all added /system/lib/soundfx files except those from the Beats™ and Huawei ™ files. Because of this, Permissive Selinux is required. The backup script is still there and your device does have the removed soundfx files in stock form so this is certainly not a compromised version. You'll have everything successful users have except for the capability of running on Enforcing Selinux.

I chose ViPER|Atmos™ Beats™ Huawei™ Edition for this test for two reasons:

It is the most popular version by a substantial margin.

Since this version includes all that is currently offered, it means that whatever is successful during this compatibility testing phase will absolutely work across every single other ViPER package.

I strongly urge those with unsuccessful attempts or even just partial installations such as Dolby Atmos™ FC's but v4a works to wipe System in TWRP, dirty flash your rom, and try one of the zips attached below. Feedback is greatly appreciated from those participating in this compatibility testing phase. I am soley focused on your compatibility issues at this time.
[Nexus 6 Themes and Apps] olivares.leody:
Sir my only problem was dolby atmos on fc but viper is okay. I even clean install my rom and flash dolby atmos r6.5 only but still got it in fc. So maybe dolby atmos is not compatible with my specific phone. Anyway i am satisfied with viper audio only. Thanks for your effort [MENTION=4445176]guitardedhero[/MENTION]

PS. If i try to dirty flash with the instruction form OP i got bootloop ( i already did it thrice)
[Nexus 6 Themes and Apps] guitardedhero:
Did you ever try any of the ViPER|Audio™ packages that contain everything except for the Dolby Atmos™ installation and have the same bootloop?

You are a great candidate and my target for the 4.0CT compatibility testing phase.
[Nexus 6 Themes and Apps] kmar22:
I've tried to install the update twice in recovery and get a "failed" message. Downloaded twice . any ideas ?
[Nexus 6 Themes and Apps] CAYCE_VII:
It's not a flashable zip...
[Nexus 6 Themes and Apps] kmar22:
Its been a long night lol thanks bro
[Nexus 6 Themes and Apps] CAYCE_VII:
It's alright, I did the same thing last night after reflashing stock. That's the only reason I knew.

Does anyone else have the problem where you play music through one music application(ex: Shuttle) and then try to play a song through a different music application (Spotify) but you get no sound through the second music application until you kill the first application?
[Nexus 6 Themes and Apps] urnamese3:
I made 2 flashable zip of version 2.3.4.0 if anyone needs them, the first one is a normal flashable zip containing Viper 2.3.4.0 so you'll need to manually flash the patches you find at

this

post and the second one has the fixes in it and also removes AudioFX, DSP manager and MusicFX
[Nexus 6 Themes and Apps] prestige2:
I really want to flash those but the last time i tried V4A all the sound in my device is gone i had to reflash my ROM again

thank you by the way it's really great

EDIT : IT WORKED FINALLY !

I couldn't resist the temptation i installed the second attachment and it work like a charm .. thank you so much
[Nexus 6 Themes and Apps] urnamese3:
No problem mate glad I helped. I can't live without viper4android now, the sound is perfect once you find the right settings.

OP Takeover

Hello all,

I did not get the Nexus 6 after I waited 2 weeks a couple months ago for T-Mobile to ship and they never did. After that I decided to wait to get a white 64gb(The Unicorn) but at this point I have no interest in getting the device after such horrible availability. With that said if anyone wants to reach out to me to take over the OP here they're more than welcome to it. I don't feel comfortable maintaining or supporting something I cannot test on.

PM me if interested and we can reach out to a mod to make the switch.
[Nexus 6 Themes and Apps] RideHardDieFree:
Thanks a lot. Spent two and a half hours dicking around until I saw this. Flash these two files and got it working. FINALLY have headphones loud enough!!:good:

That was my biggest disappointment when I got this phone. My beloved spotify was so quite.
[Nexus 6 Themes and Apps] magullo:
Thanks, I tried to flash the second zip over already installed 2.3.30 (as zip from TRWP) and cannot get to update to 2.3.4.0. Driver status says I am on 2.3.3.0.

Is there a way I can fix this (except flashing everything from the beginning, after a factory reset)?

Thanks.
[Nexus 6 Themes and Apps] chief2842:
Do you have the latest version .apk file I cannot find it?

Edit: Disregard I found it on Viper's blog.
[Nexus 6 Themes and Apps] khmerkid:
I install the 2 files fine. Now my head phone jack don't work. Any fix to this?
[Nexus 6 Themes and Apps] elevatorguy:
Try plugging cord in very slowly you should get a popup back out of it that then all should be good.
[Nexus 6 Themes and Apps] rakz992:
Guys do I have to set my selinux to permissive to get this working ?
[Nexus 6 Themes and Apps] magullo:
yes, it looks like it doesn't work without permissive permissions.
[Nexus 6 Themes and Apps] r80ies:
I am having the same issue.
[Nexus 6 Themes and Apps] khmerkid:
Anybody know a fix please?
[Nexus 6 Themes and Apps] r80ies:
I had to dirty flash stock and unroot. I did not do a media wipe. Once I booted up I was able to get sound back via headphone jack, and I installed 2.3.3.0 zip. Everything works now. I am not cautious of upgrading to 2.3.4.0 because I do not want to do that all over again.
[Nexus 6 Themes and Apps] urnamese3:
Go to Viper ->Unistall driver -> reboot -> install driver on 2.3.4.0 apk

it's not 2.3.4.0 causing it, the newest version only fixes bugs and upgrades compatibility. If you guys actually took the time to read a page or 2 back you could find these two posts which might help you:

[Nexus 6 Themes and Apps] S0UTHPAWK1LLA:
On PN w/Despair 43 and everything works. Only question I have is that when I select the audiophile profile, it has the DFX IRS, but when I look in my kernel folder, there aren't any DFX IRS there. How do I know if, though it is working, whether I am actually running a proper ViperAtmos installation?
[Nexus 6 Themes and Apps] olivares.leody:
Everytime i dirty flash with the instruction provided in the OP i got bootloop.

This is what i have done on v3.9, i have flashed viper|atmos beats huawei but dolby atmos fc so i dirty flashed with the instruction from OP to get rid of everthing from v3.9 and start with viper|audio but after "android is upgrading" my phone restarts and got to bootloop.

I will try the compatibilty test when i got time maybe after tomorrow and i will give feedback. As of now i am using v4.0 viper|audio beats huawei edition with no issues:)
[Nexus 6 Themes and Apps] tycobb:
OK where can get this driver and where should i put it?? :)
[Nexus 6 Themes and Apps] inffy:
It's in the zip file and will install when you flash the zip
[Nexus 6 Themes and Apps] tycobb:
OK then...so be so kind and tell my Viper ask me to install library and restart my phone and after that when i tap on Viper icon i still get same request? :)

- I installed Viper Audio
[Nexus 6 Themes and Apps] inffy:
Propably your /system partition doesn't have enough space our the audio_effects.conf file is not updated. Those are the most common problems
[Nexus 6 Themes and Apps] Syoenth:
what apk('s)? The V4a and Dolby atmos?
[Nexus 6 Themes and Apps] tycobb:
How can I change audio_effects.conf? How big should be system partition then?
[Nexus 6 Themes and Apps] inffy:
Sorry can't help you with there. Never used (and never will) htc phones.
[Nexus 6 Themes and Apps] guitardedhero:
Sounds like you're looking in v4a directory not being used by v4a. The two most common directories used by v4a are:

/data/media/legacy/ViPER4Android

and

/storage/emulated/0/ViPER4Android

You can also save any open v4a tab and save as a New Effect Profile named "SOUTHPAW" and then see which directory it is saved to inside the Profile folder. Your IRS files are working and active as they will not show up if not already in the working v4a directory.

Beautiful! Thank you for the report, things seem to be falling into place!
[Nexus 6 Themes and Apps] S0UTHPAWK1LLA:
Yup.. I looked in the/data folder and found what I was looking for. Just copied them to the /storage side.. :thumbup:
[Nexus 6 Themes and Apps] guitardedhero:
Yes, any apk found in a folder of the same name should be placed directly into /system/priv-app and then the app folder deleted.

/system/priv-app/XXX/XXX.apk should be:

/system/priv-app/XXX.apk for devices on JB and KK

You want at least 50mb of free space in /system.

Have you tried ViPER 4.0CT?
[Nexus 6 Themes and Apps] guitardedhero:
I would also like at least one N6 user to test 4.0CT after wiping System in TWRP and dirty flashing their current rom. If this works perfectly with no issues, 4.0CT may become 4.1 for everybody. Thanks again everybody for working with me and providing all your feedback. I certainly don't want to add additional versions to the OP attachments section lol!
[Nexus 6 Themes and Apps] Reechings:
Makes sense to me. Should I be safe to dirty flash the 4.0 zip over the RHR one? Thanks!
[Nexus 6 Themes and Apps] guitardedhero:
[MENTION=2534738]tycobb[/MENTION] Do you have an audio_effects.conf file with the "HTC" in the name or named any different than "audio_effects.conf"?

If so, change the name of it by just adding ".bak" to the end of it and then reboot.

Doing so will accomplish nothing as I left /system/addon.d/23-v4adap.sh out of that build for obvious reasons. That file update is the only update in 4.0. You're already where you want to be. :good:

Edit*

In case I misunderstood you, are you on 3.9 or on the RHR-K ViPER|Atmos™ build?

Edit**

I meant are you on RHR-K or RHR-K VIPER|Atmos™ Edition?
[Nexus 6 Themes and Apps] Syoenth:
then I just copy the apks, then reboot and install the drivers, right?
[Nexus 6 Themes and Apps] Reechings:
I'm on this one right now:

RHR-K+SRC+1.H+ViPERAtmos+Edition
[Nexus 6 Themes and Apps] rimsilva:
Do you have selinux set as permissive? Do you have busybox installed?

Maybe this will solve.
[Nexus 6 Themes and Apps] tycobb:
OK...renamed that file (/system/etc) and after reboot still Viper want to update library but this time i got error - error during library instalation :)

ViPER 4.0 OC - during flashing i got error ...can't flash it
[Nexus 6 Themes and Apps] guitardedhero:
OK, you're good to go, no need as I understood you the first time then lol!

What is the original name of that file? Also look to see if that file exists in /system/vendor/etc as that one will always override the file located in /system/etc.
[Nexus 6 Themes and Apps] guitardedhero:
If you get an error in TWRP, after bootting back up, zip this file and attach it to a reply:

/cache/recovery/lastlog
[Nexus 6 Themes and Apps] guitardedhero:
Be sure apk permissions are still set to 0644 before rebooting. Driver should already be installed.
[Nexus 6 Themes and Apps] Syoenth:
after I reboot, I install the drivers from the V4A app? I tried to install te official app from and doesn't let me install the drivers, and I have rooted my phone and I have busybox installed, I'm on a Samsung Galaxy S3 I9300
[Nexus 6 Themes and Apps] guitardedhero:
V4a should open without a prompt to install driver.
[Nexus 6 Themes and Apps] Syoenth:
whn I copy the apk, then the drivers are installed? or how I install the drivers?
[Nexus 6 Themes and Apps] guitardedhero:
Have you installed a ViPER package?
[Nexus 6 Themes and Apps] guitardedhero:
Sorry, I missed this post. Install Super Quality driver when prompted and then reboot when prompted.
[Nexus 6 Themes and Apps] Syoenth:
I installed the official version, it prompted me to install the drivers but it doen'st install, I'm on a Samsung Galaxy S3, it's rooted and with busybox installed
[Nexus 6 Themes and Apps] guitardedhero:
Do you have a custom rom zip you can flash in TWRP in your sdcard? Are you interested in a dark or light themed v4a?
[Nexus 6 Themes and Apps] Syoenth:
well, I'm on a JB stock rom, I want to install a MM rom on this phone, I had a Moto G 4G which i had installed V4A, I like the dark themed v4a ^^
[Nexus 6 Themes and Apps] Ramondel:
What I found that on my Samsung Galaxy S5 I had to have a permisive kernel once I upgraded to Lolipop. The stock kernel will not allow anything to change the Selnix from enforcing.
[Nexus 6 Themes and Apps] guitardedhero:
ViPER|Atmos™ 4.0.1CT Beats™ Huawei™ Edition​

4.0.1CT is the first update in our Compatibility Test during this testing phase. I've added /system/etc/htc_audio_effects.conf into the patching portion of the ViPER installation. This addition is obviously directed toward HTC devices but will not affect other devices. This brings the total number of audio_effects.conf patches to four (you only have two on your device, I just need to hit both of them during installation).

Great job guys, compatibility is increasing significantly and I appreciate all the feedback in helping me come up with a ViPER package that everyone can enjoy!

We're not done yet though. I still need confirmation that 4.0CT or 4.0.1CT works perfectly on the Nexus 6 and Nexus 6p. I also need confirmation that Samsung devices are not faced with the same obstacles as on 4.0 or below. I also need confirmation from HTC users that there is not another audio_effects.conf named differently outside of /system/etc.
[Nexus 6 Themes and Apps] guitardedhero:
Are you able/about to install a Marshmallow rom or just staying on JB?

Thank you for the additional info! I removed all supolicy in 4.0CT in hopes that it would increase Samsung compatibility, which it seems to have increased.

Thank you [MENTION=5328338]shabbat[/MENTION], I found the culprit. Writing install scripts on your phone with autocorrect can be a nightmare lol!

ViPER|Atmos™ 4.0.2CT Beats™ Huawei™ Edition​

Now Installable!!​

4.0.2, the second update in our Compatibility Test of our testing phase, and likely the first one to successfully flash lol, corrects an autocorrect error in updater-script that I simply did not catch.
[Nexus 6 Themes and Apps] ProRules:
Is this setting actually customized for beats headphones?

I'm going to have another build for you shortly, I think Dolby Atmos might need to be in /system/app instead.

I'm sorry man, I certainly try to help everyone I can no one will ever be ignored. Do you mind filling me in on your issue and current status? A lot of stuff happening right now with testing so it's hard for me to remember what you have going on.

Awesome! Thank you for the report!
[Nexus 6 Themes and Apps] guitardedhero:
New build just for you.

Just flash over your phone's current state.
[Nexus 6 Themes and Apps] SpasilliumNexus:
Just wanted to throw in a bit of correction on V4A credits. ViPER520 is the main developer of V4A, and zhuhang is the co-founder, English translator, and IRS creator.

http://vipersaudio.com/blog/?page_id=11

No problem intended. It just pains me a little to see ViPER520 not getting love in these audio mod threads which include V4A as part of the pack.

[Nexus 6 Themes and Apps] Syoenth:
thanks, I'll try it right now !!! ^^
[Nexus 6 Themes and Apps] guitardedhero:
No pain at all, helping you achieve a successful installation helps me as well as other users.

Try Mounting Vendor in the same steps when you uncheck System in Mount.
[Nexus 6 Themes and Apps] CNDow:
Stick with 4.02?
[Nexus 6 Themes and Apps] Ramondel:
[MENTION=4737693]guitared[/MENTION]hero, I flashed version 4.0.2 on my Samsung S5 and I get the request to install the driver as I got with version 4.0 but it will not stay installed if I do a normal reboot. If I do a hot boot it works fine until I have to I perform a normal reboot.
[Nexus 6 Themes and Apps] guitardedhero:
Yes, this part of the testing phase requires Permissive Selinux. Once this phase is completed with full compatibility across all devices, I will begin the next testing phase of Enforcing compatibility.

...assuming you used 4.02CT

Yes, be sure you have Permissive Selinux for now.
[Nexus 6 Themes and Apps] guitardedhero:
I need to know what is overriding audio_effects. Is it possible for you to zip up /system/vendor to your Drive and shoot me a link?

[Nexus 6 Themes and Apps] adm1jtg:
Having a terrible time with this as I posted earlier when I install this now ver 4.0 processing is always yes. I have tried everything I can think of to make it work properly with no avail. I have tried changing kernels and base roms I even tried changing su versions. Yes I know op has pointed out this shouldn't be an issue but this is just not how v4a has worked for me in the past at all. Whats worse is I wanted to test leakernel 3.4 and with that kernel the driver wont even load at all I get an unknown type status, possible selinux issue perhaps?

My only thoughts on the always processing is that the main kernel i was testing when I got that was a faux sound enabled one could that be the cause for processing always on?
[Nexus 6 Themes and Apps] ryanallaire:
Just wanna throw this out there, when unmounting system during the install, if you make a nandroid and forget to mount system and try to restore with that backup, it fails.. At least it did for me...
[Nexus 6 Themes and Apps] themoto:
for me it's only processing when i play music,with all the versions i have tryed.
[Nexus 6 Themes and Apps] guitardedhero:
Try the zip below or you can try Selinux Mode Changer also attached below.

I never use a kernel with Faux Sound so I don't think that's what it is. I don't know what to tell you, this was not an intended maneuver on my part and if v4a is working perfectly with no noticeable battery drain, I would just enjoy the tunes. I'm sorry, as I know that's not what you wanted to hear.

Doing a nandroid in TWRP will always mount System automatically, just like wiping System in TWRP will always mount System automatically. My suggestion to unmount System after wiping it is to bring TWRP to its original Mount state, at least in my usage. If you boot up TWRP and immediately go to Mount and see System checked, then that's different. I recommend installing zios with whatever partition mounts TWRP defaults to when booted up.

[Nexus 6 Themes and Apps] rogerinnyc:
Wow. I go away for 24 hours and the thread is 10 pages longer and you've pushed about a dozen new zips! Amazing work.

1. As reported, I'm on a Note 4 (910C), running stock rom with a permissive kernel (Talexop) -- having given up on making V4a work with an enforcing kernel (but not to lack of effort on your part!)

2. Happily running 3.9 ViperAtmos -- sounds great! But the tweaking itch never rests, so I'd like to try Huwai/Beats, but also have the possibility to revert to ViperAtmos -- all without having to dirty flash my rom (as I don't have a zip, just an Odin .tar).

3. It sounded like from an earlier answer I can just flash your new 4.02CT zip over my existing install without doing anything else?

4. And if I wanted to go back to Viper/Atmos I can just flash 4.0?

Thanks in advance!
