[TUTORIAL]...Viper4Android proper installation on stock ROM

As a few days frustration and zillion tries are behind me let me explain proper instalation of this sound engine. Just to notice that you DON'T need permissive kernel for that because I installed it on my stock German ROM and now works in French Orange ROM G935FXXU1APBF as well !
INSTALLATION PROCEDURE ON CLEAN STOCK ROM :
At first...
You need to DELETE not to freeze sound alive and adapt sound.
In build.prop find the lines or add them as follows ;
Ipa.decode=false
tunnel.decode=false
lpa.use-stagefright=false.
.
1.You need to root your SM-G935F device with newest SuperSU by ChainFire located here.So, download and flash TWRP recovery from here and flash SuperSU.Wipe dalvik,wipe cache, then Restart your device.
2.From Playstore download and install latest STERICSON BUSYBOX. Install busybox in default su/xbin and give root permission.Restart your device again.
3. Download from official page Viper4android version 2.4.0.1 from HERE
4. Using Root explorer copy Viper4Android in folder PRIV-APP and give it permission 0644 rw-r--r-- (see attached image)
5.Restart your device
6. Open V4A and install driver when it asks...don't exit app or DON'T TOUCH anything else, just Restart your device.
7. Open V4A and go to Settings - UI Setting - Expert Mode
8. In some occasions V4A will ask for new driver installation...Install again and restart device.
9. Use your V4A wisely !
IMPORTAINT NOTIFICATION !
If you previously messed up with V4A or rooting,I recommend fresh ROM installation from scratch.
If V4A constantly offers to install driver, it means you did not properly rooted your device !
VIPER4ANDROID IS NOT WORKING ON STOCK PLAYER !
That's all.If you didn't read post carefuly, there is no any support else, because it is not needed.

Followed your guide, didn't ask to install a new driver after step 8 and viper is not working any suggestions?

In some cases it doesn't ask for another driver installation after entering expert mode.Did you try another player?
If you don't used it on clean rom then it could be anything.

I've not needed to do half of this.

How come ?

BusyBox Location is Su/xbin or System/xbin ?

I read and hence the question, because usually since MM - Busybox is installed to System/xbin by default.
Nevermind, Gonna try that as well now. Thanks!

Because I simply download the latest APK and install it as a normal app rather than copy across and setting permissions.
I then download and flash the ZIP from the below site:
http://androiding.how/how-to-fix-viper4android-selinux-policy-issues-on-lollipop/
After that I installed the driver, rebooted and all was good.
I was the first\one of the first, to flash v4a on our device.

I've already created a tutorial thread for this in the guide section. People might find it easier, no need to make adjustments to build.prop for example, it's automatic.

Thank you so much for this barbik!
I've literally spent the best part of a day trying to get this to work. Followed various guides posted here but only your link applied V4A system wide rather than just for GoneMAD.
If anyone else is having issues, uninstall the driver and the app, reboot into twrp and flash this zip instead.
Thanks again you saved me a few grey hairs!

[GUIDE][HUAWEI P8][15-4-2016] Xposed Working On Lollipop & Marshmallow

Good day everyone, this is a guide on how to enable Xposed on EMUI 3.1 (Working tested by me using the deodex method) and EMUI 4.0 (Working tested by me also and confirmed working by @Blackball,). - (Update using the deodex method 10-4-2016)
First of all the original guide for making this work on Huawei roms http://forum.xda-developers.com/honor-6/general/guide-workaround-running-xposed-t3338765. Ty @mfbcool for your guide and help. Please follow his instructions to the letter for making it work on our device.
- ([15-4-2016] New Instructions on the original thread no need to deodex the rom files, a working xposed zip has been developed for Huawei devices just flash it in twrp and do the build.prop modifications before you flash the zip for your version of rom. Already tested by me)
So my role in this is to highlight all the tips needed for making it work on our device, and the issues i faced when doing it. ([15-4-2016] The original thread is self explanatory, all of the tips here are already mentioned there this thread was created when we needed to deodex the rom files. So forgive me if i am not adding much.)
Notes
- I think a lot of the members were installing the wrong xposed files for our device we need the ARM-64 SoC files for our device because it's using the Kirin 930.
The Tips:
Lollipop:
1. The xposed files needed for your device are under the heading of: on Lollipop 5.0.x is: Xposed for EMUI 3.1 Android 5.0. (If you are on Lollipop 5.1.1 is: Xposed for EMUI 3.1 Android 5.1.1, if Marshmallow: Xposed for EMUI 4.0 Android 6.0)
http://forum.xda-developers.com/android/general/guide-workaround-running-xposed-t3338765
2. Make sure that after you install the xposed apk , you go to "build.prop" in /system using any file explorer with root and edit the line "ro.config.hwtheme=1" to "ro.config.hwtheme=0" and then save the file with the defualt permissions or you will get a bootloop. why editing the build.prop is important because without changing this the framework will not be active, you will get a red message saying framework not active. The only way to activate it is by editing this line or in the xposed app go to Settings if you enable "disabled resources hooks" doing that and then restarting will activate the framework but whatever module that uses resources will not work. So the only way working without affecting the modules is editing the build.prop file.
Marshmallow:
1. Make sure to add these lines ro.config.hwtheme=0 and ro.config.hw_theme=0 in build.prop in order for xposed to work and make sure to save the file with the defualt permissions or you will get a bootloop.
If you follow the original guide exactly and the tips you should have no issues making Xposed work.
P.S: By the way first boot may take a while (15+ mins), So don't be afraid.
Special thanks again to @mfbcool for his guide & help, and @pudup for directing me to the guide.

Thanks for the guide.

I cant install xposed. When i install it, after reboot i get black screen with only one button of the navigation bar (i can access the shutdown menu from lock key, and i can access and the notification pannel, but nothing more). This is solved when i install the uninstall file.
My phone is already rooted. I firstly installed apk, and then installed xposed via twrp. I've tried to wipe the Dalvik but it doesnt solved.
My p8 is gra-L09, lollipop. Used this files: XposedInstaller_3.0_alpha4.apk, xposed-v80-sdk21-arm64.zip, xposed-uninstaller-20150831-arm64.zip.
What AM i doing wrong?

Did you deodex the rom? you have to deodex in order for xposed to work for Huawei devices, which version of Lollipop are you using?.

I flashed today the C636B320 Marshmallow firmware, and then i deodexed the rom per instructions to make xposed work on Marshmallow.
First attempt i failed because i didn't wait enough, you see the screen will get stuck on Huawei boot animation without any sign that anything is happening(no app update notification card like in Lollipop) for like a 20+ mins. Then voilà the phone booted normally. Also exposed is working fine no issues, make sure to flash xposed-v80-sdk23-arm64.zip instead of the latest one v81 which doesn't seem to work for me.

Trying to get Viper4FX sound mod to work with my Honor8

Hey guys,
I'm into the Android from the very beginning and I would love to get rid of a problem which is driving me crazy for some time
I was trying to flash the Viper driver to get the great sound quality again. I'm now on the latest nougat.
Already unlocked the bootloader, rooted it and flashed the TWRP. Saw an thread about how to install it properly on the Honor8 and I did everything correct in my opinion.
I have the 1.26.2-meefik busybox now installed in system/xbin path (which seems to be working correctly overall) and otherwise everything seems working good except that when I try to open the Viper it says that I don't have root OR that i have to install the driver, and after pressing yes my phone just reboots and does the very same thing as previously.
Am I missing something?
Feel free to ask something more if you need.

I had this same situation, just kept installing the driver, reboot, repeat, making no progress... I finally got mine to work thank goodness! Are you remembering to use a root file Explorer and go to /vendor/etc and rename the file named audio_effects.config to audio_effects.config.bak after flashing but before installing V4A? That was my main problem. And you have to be sure to do it on a clean setup, so if you've already installed V4A you need to clean out and start again. Also u need a kernel auditor to set selinux to permissive upon boot. These two steps are key...

3. opem BusyBox tap Install
4. open Kernel Adiutor and go to Misc Controls, change Current SELinux Status: Permissive (after reboot SELinux stay premissive :good
5. flash Viper4 via TWRP
6. go to folder: root/vendor/etc and rename file from audio_effects.conf to audio_effects.conf.bak

Problem installing viper4android.

Hi guys,
I am using the optimized stock rom located here. aaaaawawawaa using BitO-KU kernel. The sound is very low on my Nvidia Shield k1. I have done the tweaks located here. In the thread it says that viper4android makes a big difference as well. When I try to install viper4android I keep getting an I/O error when trying to install the driver. I downloaded SELinux changer but when I launch it I am getting an error in it as well. It says the app was unable to gain root access. I checked in supersu and SELinuxModeChanger does have root access. So I don't understand why it will not work either. In terminal emmulator it says that permissive mode is enabled. Can someone please let me know what I'm doing wrong? I would really like to get viper4android working.
Thank you,
Rocky

1. It isn't good rom, I've had it only two days. Stock kernel is better too.
2. I'm on stock 5.2(K1), rooted with Magisk 14, installed M modules:
V4A 2.0 by ahrion, busybox by osm0sis. V4A works good but I don't need it for speakers. @grimreaper1014
Do you have properly installed busybox?

Just flash Viper4Android using Magisk 14 (its located under downloads tab) and disable AudioFX if you even have that on stock ROM. Then it should work but note that if you get processing error just create a folder named "MagiskManager" and it should work then.

Ok thanks guys. Right now I have SuperSu flashed via recovery. Do I have to remove that somehow to install magisk?

I'm doing a clean install. I'm going back to LinageOS. Where do I create the MagiskManager folder at if I need it? Thanks again for your help fellas. I appreciate it greatly.

@grimreaper1014 create the folder in /storage/emulated/0/ in case it doesn't want to install the module. If it goes without any problems then congrats you have working Viper4Android !
(Make sure you disable AudiFX app in lineageOS before you do any flashing)

If for some reason you (or others) choose this route, you can remove SuperSU (mandatory in order to install Magisk) using the built-in function in the SuperSU app.

Similar setup: stock 5.2 ROM, with Magisk 14, and simply installed the V4A (version 2.0) module by ahrion. I think the module installed busybox (by osm0sis) automatically, as I don't recall doing it myself. But I maybe I'm not remembering that properly.
V4A working great, no messing with SELinux.

[SysMounter] Flash Xposed/Dolby Audio zips in Mi A1

Hi Guys,
We all know that we are unable to flash old zips (which are not optimised for A/B partition) on our Mi A1.
There are some modifications to be done in each and every zip to be able to flash it properly.
I found a simple solution to do this.
SysMounter zip in the attachment will mount and bind your system partition at the correct place so that your zips can identify it and flash successfully.
Steps:
1. Flash SysMounter.zip
2. Flash any zip you want for ex. Xposed Zip or Dolby Audio zip
3. Flash SysUnmounter.zip (not mandatory)
Download in attachments.
thanks

You think this would work with Magisk?

sysunmounter.zip gives error while flashing..

Razer Phone has an inbuilt dolby system in stock android. Would be great if someone ports it.
