V4A Driver Won't Stick - Nexus 5X Q&A, Help & Troubleshooting

I Flashed V4A_2.3.4.0_Enforcing_Lollipop.zip with TWRP on stock, rooted 6.0.1 nexus 5x, with Busybox installed, SuperSU mount namespace unchecked and selinux both permissive and enforcing and can't get driver to stick! I'm Prompted to install after every reboot. App storage perms are on. Any help most appreciated. Thx
I've posted my question in two other threads but none has answered

You need to delete the file "audio_effects.conf" in /root/vendor/etc/ Use a file explorer or something else you can get access to edit root files

Stop with the old stuff, so many things to do to get it working. Just flash latest version by guitardedhero or flash the new ARISE sound mod. Guitardedhero has worked so hard to make these mods super compatible.

Thanks to both of you. Pollie, I am unfamiliar with Guitardedhero. Can you please provide a link?
Hypemanisus, I did as you suggested, and while I am no longer prompted to update the driver upon opening V4A, and in fact the option in settings says ,"Uninstall Driver," driver status is still No, Unsupported an Abnormal across the board. Indeed I am not hearing any enhancement either as I certainly did hear with my Nexus 6 and Galaxy S4.

http://forum.xda-developers.com/android/software/viperaudio-viperatmos-3-8-sq-driver-t3289075 , isntall the universal version , should work .

Thanks Apyah. I will get around to this this weekend and advise

Flashed Dolby Atmos as directed. It is stopping upon opening. Perhaps there is conflict with previous version of V4A, which I removed using a root uninstaller. Advice?

Is there a flashable uninstall zip for the above V4A system app? Concerned some files might have been left behind which are conflicting with guitardedhero. Tried dr ketan fix too with v4a didn't allow driver install either

But then again I really have no idea. Quite frustrated. NEED MY VIPER compulsively!

what did you flash ? don't flash dolby atmos , just flash universal version , it has dolby and viper , just turn off dolby and use viper , don't delete anything .

Perhaps i'm crazy but there's no more link for the Viper|Audio. Only Viper|Atmos and DD.

Cannot find Guitarded Hero Universal Audio system app so I installed the latest V4A user app (V2.4.0.1). Removed "audio_effects.conf" from /root/vendor/etc/. Set SelLInux to permissive. Installed Driver. SOFT reboot and it now works. Still upset though because It's a pain to have to setenforce 0 then soft reboot and run phone in permissive every time. Coulda sworn i read somewhere a script to get this to run in enforcing...

no need permissive , i just flash the universal version on my 5X and G2 (5X hard brick now) viper work on both phone in enforcing SElinux .
Try reinstall your rom , clean wipe .

Thx Apayah. Where can I find this universal version you speak of please?

the one i gave to you , or to be simple http://forum.xda-developers.com/attachment.php?attachmentid=3701983&d=1459364213

Xposed Framework (LolliPop)

As I am well aware most of the regulars on these threads know xposed framework has fnally been implanted with ART. Unfortunely, as of right now it's not a simple install an APK, set SU access, go for gold. There have been a **** load of problems going on for a lot of people. Has anyone got xposed to work properly on their devices and how did you go about to doing it ? I already have SELinux set to permissive, but the log from xposed is reading something about modules.list.....

Working fine for me. I just followed the instructions they posted online. Flash the .zip, install the apk, and then install modules. I'm using a bootmanager, youtube adaway, and Pandora Patcher. I'm running BadBoyz latest Sprint Lollipop ROM.

Just bootmanager. Click outside the not installed dialog. I read somewhere it works otherwise. I think it's working but really haven't messed with besides stopping a handful of apps.

Is selinux permissive?
The procedure I use is
1. Copy apk to system/priv-app/v4a/(make the folder)
2. Permissions (rwx, rwx, rwx)
3. Reboot, install driver (I haven't disabled lpa)
4. Reboot, and you've got it working!
My selinux is set permissive from the kernel I use (elementalx) if it makes a difference..

Viper audio mod + lollipop

Has anyone been able to get this working? If so, how?
AOSP lollipop, download official V4A LP, flash it. Set kernel to permissive and install drivers.
On Touchwiz however v4a works via same method, but the devices memory killer always kills v4a even if you have it installed or notification turned on unless you somehow set v4a as high priority to not be killed.
I think found a solution for TW Lollipop V4A if someone wants to try the last thing I did to get it working.
Freeze SoundAlive with Titanium Backup. Couldn't find Settings/Sound/effects. After searching and trying everything, the last step nearly had me stumped.
If it makes any difference, I'm still on the stock OTA OB7.

If that doesn't do it, I had also installed viper to /system/priv-app in a folder with arm and lib sub folders with the .odex but didn't get a generated .odex.art file in arm folder so I get a quick "Android is updating... Starting apps" on each boot. I'm not sure that Odex is necessary. But since some are saying lollipop oom kills viper quickly, the deodexed version in /system/priv-app folder with lib sub folder may be necessary.
But I believe the permissive kernel is necessary: 3.10.40-N4-Sprint_AELKernel-v1-LP

Sun Mar 15 21:34:07 EET 2015 Thanks; haven't got anything setup with it, just got viper going.
How did you get SELINUX into permissive mode? was it the new AEL kernel? I stopped Soundalive and have been using ExtremeBeats. Sounds pretty good. Not like a viper though.

Yes; AEL. I copied the kernel description but didn't post a link because of the requests not to. But there are links in the old/discontinued thread. That's where I got the kernel.
I saw a new AEL kernel out also. Ill have to give that a go when I get sat down. HOpe it works. I think itll fix my Cleanmaster in shutting down startup apps.
Definitely works with permissive set so selinux.

[Rom][Custom]Doogee Dagger DG550 DM550 Kitkat 4.4.2 02/11/2015

I'm using it about week and it's working good. A lot better than original 4.4.2 rom by Doogee.
Make A Backup Before Flashing I Will Not Be Held Responsible For Loss Of Data. I Will Not Be Responsible For A Bricked Device.
Only for MTK6592 DG550 and DM550!
Installation
Donwload newest SP flash tool and flash this to you phone like original Kitkat. You can also use TWRP 2.8.1 But I've got errer when I flash this recovery, but it was flash anyway. So I recommed flash whole rom in SP flash tool than flash again only TWRP 2.8.1 if it end with error never mind it should be flashed, I try to flash it again and it was end with error again but when I booted to recovery it is working without errors. In recovery flash Super SU 2.46 for root, working great!
If you don't use custom recovery, for root use Kingo Root Then download Super SU from Google Play and install new binaries in the app. After that delete both Kingo Root app with Rom Toolbox or other app like that. Now you can flash TWRP in MobileUncle (2.8.1 doesn't work for me, only in SP flash tools with error but worked) you can flash TWRP 2.7.1 or other recovery.
You can follow this video. Don't forget install drivers if you don't have it!
https://www.youtube.com/watch?v=5rhvBPuiE78
Pros
No more battery drain!
Deep sleep working great
Should included new camera driver - I Don't have the new camera so I can't confirm it! Let me know if it trully has.
Cons
No gps.conf - Reset GPS in MobileUncle and download Faster GPS and make gps.conf file just right for you.
I will update it with GPS.conf file and other tweaks as I tested it, but I'm going on holiday for a week so it will be in the end of the June.
Tweaks
eXtremeBeats™ - for much better audio, but I can't get working Busybox, so you can set bass booster or EQ, just use as it was by default, still better than original audio. Flash it in recovery and delete cache and dalvik cache.
If you now how to get Busybox to work please post it here. For ExtremeBeats it should be Busyboxy by Stericson, but it doesn't work neither.

DG550 Kitkat 02/11/2015
Blackview original upload
Thanks for sharing this! I installed the rom and everything is working fine except for the camera. It can't focus so all the photos comes out blurry. I have the first versione of the DG550, in fact with the 15/08/14 rom the camera is perfect. It happens also with new versions of the original rom i don't what to do to make it work. Any hint?
So are you just posting the BlackView rom, or have you made any useful changes?

Then why is it listed as a custom ROM? I has been listed in the main DG550 thread for months.

Need your advice about rooting D5303 5.1.1

I am trying to root my phone via Kingroot, then I received this message:

Is it OK for me to tap the button below to continue the rooting process? I'm kinda having second thoughts about this, and I want your professional advice about this... Thanks in advance!

Yes, why u are rooting..can I know
I'm planning to install V4A, that's why I want to root my phone.
BTW, when I tried to tap that blue button, it says that rooting was successful, but when I restarted my phone, it went to a bootloop. Upon googling, I found another method to root 5.1.1, which is to downgrade to a lower firmware, then root, install recovery, then flash a pre-rooted 5.1.1 ROM. Now I'm rooted ?

Now you need to change kinguser to supersu as kinguser doesn't give the same root access permissions as supersu does. Also to make viperaudio work on 5.1 you must
1. select awesome player in developer options.
2. Disable music fx apk in settings/apps.
3. Install selinuxmode changer and set to permissive.
Viperaudio should now work flawlessly

I'm not sure if you were successful with the installation but I got an alternative method for SElinux change.
Install V4A with drivers then go to your recovery and flash this zip. Most devs do not recommend changing SElinux to Permissive for security reasons, this zip will whitelist V4A in SElinux Enforcing.
If you're new to V4A, go to these settings, sounds better than my walkman.
