__________________________________________________________________________________________________
FAQ:
Question: Why not use the Playstore version?
Answer: It's not officially maintained by the Viper4Android devs, this is easy and secure and up to date.
Question: Why do i need the SELinux Changer application?
Answer: Our firmware comes with SELinux mode ENFORCING, which does not allow Viper4Android the permissions it needs to install properly and installation without this will result in only the Viper4Android app working and making no changes to the sound quality as the sound driver fails to work. What this app does is change the mode to PERMISSIVE, which gives it the permissions to install properly so the sound driver installs successfully.
Question: Can i uninstall SELinux Changer application after installation?
Answer: No, the sound driver will fail as soon as you remove it, as it goes back to ENFORCING mode.
Question: I followed the instructions but i still did not notice any sound improvements?
Answer: Try rebooting and wait a couple minutes then open SELinux Changer and make sure it has root access and select PERMISSIVE and make sure It's on by closing and opening it and reboot and try again
*Reinstall the sound driver
*Make sure you tick Enable Viper4Android in all the tabs if you don't know which one your audio is played through and just to be sure
*Post in the Viper4android thread
Question: Can i install this as a user app? And is this a system app?
Answer: Yes you can install it as a user app but you might have problems with installation. Yes this is a system app.

Did you follow the instructions correctly? I think you did not follow the SELinux changer part.

I followed it all. Btw, i got unlocked bootloader and I used eagleroottool to root my device
Edit: It says "Driver installation failed, the busybox found on your device doesn't work. this usually means you installed the wrong or broken busybox, V4A needs stericson busybox to work. If you are sure about having installed the proper busybox, then please confirm your device has been properly rooted."

I would like to share to you a sound setup that would improve the sound quality of your device to your preferences. This is a bunch of guides I searched in XDA forums and tested them with my PAC-ROM KK RC-3 setup. Though it is a software-level modification, I found the end result quite pleasing.
Disclaimer:
I am not responsible for any damage that this may cause you. As a golden rule, make sure you to run a full backup of your current setup in case something goes wrong with the process. I have only tested this in my device (model: S7562). Do follow the instructions extensively.
Pre-requisite:
~An android 4.4.4 Custom ROM
~Latest TWRP custom recovery built
~With root and Busybox installed
Instructions:
1.) Download and flash the 4.4.x Viper4android driver found here.
2.) Run this current Viper4android app. That should prompt a driver installation dialog box. Proceed installing it and choose what ever mode.
3.) Download and install the latest Viper4android apk. (currently using 2.5.0.5).
4.) Run this latest Viper4android app in order to update the driver to the latest.
5.) You can now disable the old Viper4android app (the one with the violet icon).
6.) Setup the Viper4android the way you like it, and also use a music player that integrates an equalizer (like Phonography or Spotify) and your good to go.
Current headset profile (got it from this):
Master power - on
Playback gain control - off
FET compressor - off
Viper DDC - on, set to sennheiser hd558
Spectrum extension - on, set to 1.0
Firequalizer - off
Convolver - on, set to Samsung soundalive tubeamp(included in the IRS samples)
Differential surround, field surround, headphone surround+, reverberation - all set to off
Dynamic system - off
Viper bass - off
Viper clarity - off
Tube sound simulator - off
AnalogX - on, set to extreme
Rest all are turned off or kept the default.

===ACHTUNG=========================================================
For FYT SoM (5009/6011/6021/6022/6023) based JOYING / Intel SoFIA units ONLY!
Hello, here is a custom rom based on the SYU Stock Build [sofia3gr_car_64-userdebug 6.0.1 MMB29M eng.bsp.20180110.181524 release-keys]
Your Head Unit MUST ALREADY BE ROOTED! You must be able to obtain Super User access within Android!
Due to Bluetooth, WiFi, and as well as nvram patches in the ROM and bootloader, you must be running Joying 6.0 firmware dated 2017_12_15 or later to install this ROM.
Why this ROM? Simple answer: It's makes your Head Unit faster than running the stock ROM's, has updated Google Apps, and has the bloat removed! It's pre-rooted also!
INSTALLATION INSTRUCTIONS:
Step 1: Unzip the contents to the root of your USB flash drive on your computer, then plug the flash drive into the Joying unit via USB.
Step 2. Use the Android helper application "custom" to install. Download from link below, either on the Head Unit itself, OR on PC and transfer using ADB. Once installed, open the program, and grant superuser privileges when prompted, you'll be presented with screen as here:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Step 3: Click INSTALL CUSTOM. Wait for output to say recovery successfully installed!
If you wish to preserve your /data, AKA dirty-flash, click on "Do not wipe data" at this point to prevent your data partition from being wiped.
ALL EXISTING DATA ON UNIT WILL BE ERASED. THIS IS A CLEAN INSTALLATION!
Step 4: click REBOOT TO INSTALL GTX ROM - Your Joying unit will reboot, and installation will automatically proceed through TWRP.
(NOTE! The ROM automatically re-installs stock recovery during installation, so if something goes wrong, you can always restore to the original JOYING firmware.)
Recovery options:
RESTORE STOCK - Restores the original stock recovery
INSTALL CUSTOM - Installs superdave's custom recovery (needed to install this ROM)
VERIFY RECOVERY - tells you which recovery you have installed
Rom Utilities:
(all options on this menu work only if you have custom recovery installed)
"Do Not Wipe Data" Switch - enable this to prevent your /data partition from being wiped when installing the ROM. (Your results may vary. Works for me!)
REBOOT TO TWRP - Reboots to TWRP home screen allowing you to do things
INSTALL GTX ROM- installs joying_gtx stock rom from installation media
Exit - exit custom

Q / A:
Q: Do I need to worry about what MCU version I have before I use your rom?
A: Maybe, GTX ROM doesn't touch the MCU, which shouldn't be re-flashed with each install anyway as it usually doesn't change. Whatever MCU version you have, this ROM will work for you, as long as you have an FYT based SoM unit. If you encounter errors, you might need to change the "ro.build.fytmanufacturer" property in /system/app/fyt.prop to match whatever your unit ORIGINALLY came with.
Q: I have a RK3066/RK3188/PX3/PX5 based head unit. Will this ROM work for me?
A: NO! This ROM ONLY works on FYT based head units. This means all Joying Intel units, as well as some from other brands.
Q: I like Live Wallpapers. How do I enable them?
A: Use the built in terminal. type su and hit enter. You now have root. then type in:
Code:
cp -R /system/vendor/oem/LiveWall* /system/app
hit enter again, then reboot!
Q: I don't want to use this ROM anymore, what do i do?
A: Use the helper application, custom, open the program, and click RESTORE STOCK. This will restore the STOCK RECOVERY. Go on Joying's website [link], download the firmware of your choice, and follow their instructions.
Q: Can I use google voice to make hands free calls?
A: You sure can. Use the "Voice Search" app to dial a number using your voice, once at the Google App screen, click on the hamburger menu, and then select GV CallHandler 4 Joying. Make sure your unit is set to a DPI of at least 161dpi or greater, and then clear data on the google app. After you reboot, you should be able to make calls.
Q: How do I view my front camera?
A: If you are using the analog RCA video input, on the back of the unit, you can use the RIGHT CAMERA app to view. Note, than unlike the AUX program, this one will NOT mute the system audio.
Q: How can I fix my GPS speed to calculate 1/kmh or 1/mph steps instead of the default 4 steps?
A: Go to XPOSED INSTALLER, and enable the GPSSpeedFix module. Reboot, and the steps will be fixed.
Q: How can I enable different DPI settings for each application?
A: Go to XPOSED INSTALLER, and enable the App Settings module. Exit the installer, and open the App Settings to make your adjustments. Reboot, and your changes will be visible.
Q: This ROM is fast, but I want more speed, what do I do?
A: Add a fan to your unit, preferably a FAN + Heatsink. Then download an app like SetCPU to lock your CPU to MAX speed. Be careful.
Q: How do I re-assign the hard keys on my unit? Joying says that DVD and EJECT don't work! Is this a lie?
A: Yes! There is a way to re-assign keys, and the DVD and EJECT keys do actually work, the software that comes with the unit is not very good. Check @surfer63's XSofiaTweaker thread for more info on how this works.
Q: I want to send and receive my text messages on my Joying unit...is this possible?
A: Sure! Use third party app like Pulse, or Pushbullet. Works like a charm. I personally use Pulse, it's got the look and feel of a stock SMS app.
Q: Installing the Joying Factory Rom takes like an hour...multiple reboots, then it starts over, then it reboots, then it optimizes apps, then it starts over, again. jeez. How long does your ROM take to install?
A: Installation is less than 4 minutes. First boot is timed at one minute 53 seconds, and there are no crashes or reboots. It just works.
Q: Xposed says there is an update available! Is it safe to update Xposed?
A: NO! Do NOT update Xposed, it will make your unit non-functional! Just say NO!
Q: Am I able to "upgrade" from an earlier version of the ROM to a newer without loosing my data and apps?
A: Yes, read the first post on what option to select in custom. Many others and I have tested, and it works for almost all people, still there is a chance that it could not work.
Q: I need to download the stock Joying firmware so I may use your ROM! Where do I get the latest updates?
A: See here: https://drive.google.com/open?id=1nF5Pgn95_WWGk8S2byb8rR5ko0ss5F_S
Q: is there a video where I can see you install the ROM?
A:
Issues:
-Unable to send text message via google voice app using Pulse SMS, error is "Message couldn't be sent" // If anyone has a fix for this, please let us know
-Google Assistant doesn't work, launching activity manually results in "The Google Assistant doesn't work on this device" / You can fix this by changing the resolution to at least 720. use the command wm size to change the screen resolution or another tool that can change DPI

Actually it is one and the same app with different screen-layouts and functionality depending on the hardware.
The digital amp software is included.
Reserved.
As soon as I have time I will try this rom
the russian hackers at 4pda are using the following build.prop mods, anyone care to chime in? if they actually do something, I will include them.
Code:

ro.wifi.channels=14
media.stagefright.enable-http=true
media.stagefright.enable-player=true
media.stagefright.enable-meta=true
media.stagefright.enable-scan=false
I have no idea about the build props.
The custom V3 app did install the recovery image in one go. I do not know whether you improved something or the previous time was a glitch on my system when it gave that verification error.
I installed the V3 ROM. It works fine. It seems indeed faster than the original joying stock rom.
From what date are the GAPPS? The unit is trying to update all gapps. It is not really useful to have everything pre-odexed for a quick start (and it really is a quick start), when it immediately starts updating once you have finished the Google account setup.
(I myself also prefer the GAPPS micro package. I don't need and want google photos, youtube, google fit, etc. on my head unit.)
My JET apk is only partly working. At this moment I do not know why.
Replacing apps with mods (radio, BT, sofiaserver) works again now the apps are installed in /system/app
Copying the launcher.sh to /data does work. The launcher.sh works with the SofiaServer keymod as well as with the Xposed module sofiaservercustomkeymod (the one that uses the launcher.sh).
Installing a newer version ór installing one of the xposed modules currently doesn't work as it requires the package installer. The default package installer has been replaced by the googlepackageinstallers from the gapps. As such I can easily work around it by simply writing the apps to their folder in /system/apps. As soon as I upload my modules to the global xposed repository it is no problem anymore anyway as the Xposed installer can install it. I will still looking into why that one can install and my app not. I will also uninstall the google installer and replace it with the default package installer and see what happens.
And with regard to the customkeymod xposed module with settings screen: The settings screen itself works fine, but I still can't use the settings from my app. They stay empty.
Ok, if you think the microgapps is lighter I can cook that in.

You might even consider nano or pico gapps and let users just install whatever else they need manually.
I'll do nano on v4 release which will be out tonight.

Is Viper4Android working on this ROM?
Some time ago you said that you will investigate why is not working on the stock Joying but you never returned with an answer, can you please share your findings if you have any?
Thank you !

I second this .... I also prefer things kept extremely simple !
haven't tested viper. I will install it tonight and test it tomorrow morning on my drive.
If you are someone like me who encountered countless problems while installing Viper4Android on your Android 10 or 11 device and have no idea what to do then you are in the right place. Just download and install the apk from the attachment below.
You need to be rooted with magisk but you can still give it a try if you don't have magisk on your device.
Steps -
* Disable MusicFX or any other sound mod you are using either from Setting/App Manager/Apps or by installing Ainur Narsil magisk module
* Reboot
* Now remove Ainur Narsil magisk module from magisk and install Audio Modification Library (This is required in case you have leftovers from last sound mod)
* Reboot
* Now download the app from the attachment
* Install and open the apk. The app will ask you to install drivers. HIT OK
* The phone will automatically reboot and install Viper4Android magisk module
* Open the app and check. It should be working by now.
If it doesn't work -
* Install Audio Compatibility Patch magisk module. By now you will have two magisk module installed. (Audio Modification Library and Audio Compatibility Patch)
* Reboot
* Open the app. It should work now
* Still no? - Turn on legacy mode from app setting
* Still no? - Turn on compatibility mode from app setting
V4A should totally work by now
Edit : On one plus phones you need to change your seLinux mode to permissive first and then install viper4android.
Use seLinux Mode Changer for that.
Edit: All files are attached at the bottom of the post
Edit 2 -
If none of the above solution is working for you.
Download Viper4Andrpid app from here
Download latest Magisk 21.4 from here
- Flash magisk from recovery
- Then open the Viper4Andrpid app and it'll ask you to update the drivers (or won't, depending on if you already have the drivers installed)
- If phone reboots then open the app again and turn on legacy mode from options
- If phone doesn't reboot, go to options and turn on legacy mode
It should be working now
Edit 3-
If the above two methods don't work and you have enforcing SELinux, try this.
• Disable MusicFX
• Install magisk 22.1
• Install Ainur Narsil magisk module
• Reboot
• Go to magisk and remove Ainur Narsil magisk module
• Download Viper4Android 2.7.2.1 from here
• Open it. It will ask you to install drivers. Click Ok and the phone will reboot. Don't panic.
• Open Viper4Android. Turn on Legacy mode. You will see the Viper4Android app icon on your status bar.
• Go to magisk. Install Audio Modification Library magisk module.
• Reboot
• Go to magisk again and install Audio Compatibility Patch magisk and select the options mentioned below -
- Patch Audio Policy : Vol- (no)
- Patch method : Vol+ (new logic)
- Remove notification helper : Vol- (no)
- Patch USB policy for USB dacs? : Vol- (no)
- Use lib workaround: Vol- (no)
• Reboot
• Open your music player and play a song to check if Viper4Android works now
• If you have never used V4A before, just turn on Master Limiter and Speaker Optimization
If that fails too -
• Unistall Viper4Android app
• Remove Audio Compatibility patch
• Reboot
• Install Viper4Android app and open it
• Enable Legacy mode from top right
• Play a song from your Music Player and turn on Master Limiter in the Viper4Android app
• Now turn on speaker optimization
If Viper4Android doesn't process in the Youtube app or Spotify, install the Audio Compatibility patch like I mentioned above and reboot
Fix 6:
If none of the methods above works then it's likely you messed up somewhere in the process. Unistall all the modules and Viper4Android.
Download the SeLinuxMode Changer app and set your SELinux to permissive. (If you want that)

Reboot and go to the top of the post. Follow the very first method.
Fix 7: (May 11, 2022)
I have added Aosp Soundfx remover and V4a fx 2.7.2.1 in the attachment.
Flash Aosp Soundfx remover
Reboot
Turn on mobile data/wifi
Flash v4a fx 2721
Reboot
Open Viper4Android app and install the drivers (if the app is asking you to install)
Reboot
Edit : If you encounter distorted/buggy/laggy audio, clean install viper4android again. But this time keep Ainur Narsil and Audio Modification Library magisk module installed
In OnePlus devices or OxygenOS roms you might need to install the driver twice or thrice.

I did not create the app. I just found a way to get it working in some complicated Android 10 - 12 roms
Thanks for reading and have a nice day!
Edit 69:
If the audio isn't loud enough, go to master limiter, drag that output gain slider to right(6db).
If it's still not loud enough, turn on playback game control, tap on it and customize gain and threshold to your liking.
For others,you can test Wavelet from Wit,its awesome app,same dev.
thank you very much it worked perfectly

In one plus phones you need to change your seLinux mode to permissive first and then install viper4android.

OK, Thanks .

I'm SOOOOOO CLOSE to getting it working. Followed your instructions to the letter, and I get everything looking good in the driver status EXCEPT for PROCESSING. It's still a no and that's with tweaking compatibility and legacy. Any final tips?? Thanks.
Can confirm this works on the OnePlus 8 Pro running Android 11, on the xxx no limits magisk module. Thanks so much.

For some phones you need to change SeLinux to permissive to get V4A to work.
But changing seLinux to permissive is unhealthy for your phone cause it might open backdoor for some apps to take advantage of your root access.
I am updating the app and magisk now. Come back here 30 minutes later and see if the new solution works.

Play a song in your device music player.
Then open Viper4Android app, Go to that CPU lookalike icon on the top right, it will show you the driver status.
Take a screenshot and share it here.
Don't forget to keep the music player running while taking the screenshot.

Have you tried the second apk and magisk?
Is one plus 7t pro and 7 pro similar?
Cause a few days ago I've set up Viper using this method on 7 pro A11 OOS beta.

Just gave it a go, and still no luck
I'm not too sure on the differences between the two devices, though I wouldn't imagine they'd be vast. Once OOS11 comes out of beta I intend on doing a clean install, so perhaps then is the time to give this another shot.

Sorry it didn't work. Does your rom comes with a pre-installed equalizer/sound system like Dolby?
You guys should just flash the magisk viper 2.7.2 module it usually works and if it doesn't flash the other sound mods and audio sound mod lib. I found that trick back in oreo. However the samsung oneui devices are the hardest because they only come with enforcing kernel unless a dev makes a permissive kernel. I prefer 2.3.4 with the super driver but you have to have a permissive kernel on samsung. You also need to have busybox installed in magisk. With android 11 one ui 3.1 on samsung you need to use legacy mode again unless you have a permissive kernel than just busybox and viper 4.4 module installed with 2.3.4 as a user app that's my favorite. Right now I'm stuck on 2.7.2 because no permissive kernel for oneui 3.1 yet
Perfect, thanks for sharing.
