I have Viper4Android working on ElementalX kernel, Magisk 14.5 using Ahrion's Viper4Android downloaded through Magisk. The module was also flashed though Magisk. Working great so far!

Viper4Android on Lollipop Preview LPX13D?

Hi All,
I've come across some people who've stated they've got Viper4Android running but I can't seem to get it running. My nexus 5 is rooted and I've had to use "busybox x" which installs ok but when ever I install the driver on Viper4Android it just gets a driver install loop where it asks to install a driver every time I reboot. Any ideas?
Cheers.

Reflash rom and install again
Install driver without installing busybox

Hi,

Trouble installing viper4android driver.

Anyone have trouble getting the driver to install? I had it working on stock, but then I flashed cm12.1 to try it out, and when I restored my stock ROM it won't install the driver anymore.

Ensure that you're rooted, better to be using SuperSU, but it'll work on anything else. Driver installation can take a few minutes.

It gives me errors when installing the driver. It's either that busy box isn't installed (which it is ) or that the version of Android or ROM isn't compatible. I'm also rooted.

By any chance are you using supersu v2. 65 or updated your supersu binary before installing viper? I believe it have something to do with that because I was having the same problem with RR rom by The Marionette . I've fixed it by reflashing supersu v2.46. Try doing that and see if it is work.

I did update the binary, but I already flashed SuperSU to 2.46, and still the same. I'm gonna try flashing 2.44 and see if that does it. I'm really missing v4a

Try uninstall v4a app first. Then reflash SU but do not update it. Now install v4a app and it driver. I'm using the latest v4a v2.4.0.1. If it's still the fail then I sorry i can't help you because that's what I did to correct my error.

How do I install Viper4Android on 8.1.0?

Hi all!
I'm new here and have just recently rooted my Google Pixel 2 with Magisk and a custom kernel " Flash ". I have tried many guides and tutorials on how to install viper audio's drivers but after rebooting nothing works and asks me to install the drivers again once I open the app. I do also have the latest APK installed on my phone if that helps.
Is there any proper tutorials on where I can rectify the problem? As I think the Pixel 2's audio is a bit quiet and want to enjoy my Bose Wireless Earphones with my phone and have custom equalizer controls like I have with my iPhone 6s that's jailbroken.
I would also like some more info on how to flash zips to my phone as I think I may have done it wrong. Booting to TWRP than sideloading the zip.
Cheers,

I guess you have to install it via magisk

Did you read the Viper4Android thread? Flash kernel has issues with V4A.
Switch to Snoke kernel and see if that fixes it.

Can you link me to the Viper4Android thread where it says this as there is alot of pages to sift through?
Also how do you re flash a kernel? do you have to flash the stock and then a custom? Or can you just flash a custom one over an already custom kernel?

Flash stock boot & dtbo.
In TWRP: flash Snoke kernel zip (R1 is for 8.1 and at the top of the download page)
If issues, uninstall and reinstall Viper4Android 2.5.0.4 through Magisk

I have ElementalX kernel and I just downloaded the Ahrion ViPER4Android FX and flashed through Magisk. Works like a charm.

Does this work on the " Flash " kernel?
Installed the APK and it now comes up with an error saying " Driver install failed: The busybox instalation found on your device does not work".
I currently have the latest busybox installed via play store

Yes it works for oreo. I'm rooted with Magisk on Flash kernel and this is what i did and am running on 8.1:
-Go in to Magisk and download the ViPER4Android FX v2.9 by ahrion, zackptg5
-Install it and when it prompts you, select new driver (vol up) and material version (volume up)
-Let Magisk install everything and simply reboot your phone
Running V4A with bluetooth, aux, etc working perfectly

Tried this way but for me (custom ROM on Oreo 8.0) it did not work.
However, neyesor's method & files have done the trick:good:

does v4a require xposed to be installed? i'd like to use this but since xposed doesn't pass safetynet i'm cautious as to what modules i'm using in magisk

No, V4A does not require Xposed to be installed as it can be downloaded as a Magisk module which is patched to pass safteynet. I love Xposed and modules are just now starting to pop up for Oreo.... but i use android pay way too much to not have safteynet pass. So just download from Magisk

Guide to get Viper working on Android 10 custom ROMs

Here's what I did to get Viper working on Android 10 custom ROMs on Poco F1, I've looked at various methods from different sources and this finally worked for me.
Note that I'm not responsible for anything that happens to your device!
1. Reboot into recovery, flash v4a_rootless zip (drivers)
2. Flash Audio-Modification-Library in recovery
3. Reboot to system
4. Flash v4afx_2.7.1.0 in magisk
5. Change SELinux to permissive and reboot
Note that if your ROM is already permissive then it must work after step 4 and reboot
Tested on Havoc OS 3.0
Need SELinux enforcing? Try this: https://forum.xda-developers.com/showpost.php?p=81138825&postcount=16
It worked! I can't believe finally something worked! I can't thank you enough man!
Will this magisk module cause bootloop?
It worked for me too. Thanks so much

Not if you followed the instructions prior to flashing it (manual drivers and aml from twrp)

You need to connect to the internet. The installer downloads the latest apk, then the installation will continue.

Viper installation in magisk needs internet connection
Edit: fixed after installing drivers zip again n removing audio mod from magisk.
But V4a stops working once u toggle on off button. U gotta stop the app and start it again to make it work with V4a ? if u toggle on button on V4a without fcing app it won't work
And what about Dolby Atmos there is any solution

haven't tried it myself yet.
I found another method which works with SELinux enforcing. Needs magisk installed.
1. Install the 2.7.1.0 viper apk from XDA Labs
2. Open the apk, grant it superuser access and press restart on the popup
3. Press power+volume up to go into recovery while it is restarting (dont let it restart, go into recovery instead)
4. Go to terminal in TWRP and navigate to /data/adb/modules/ViPER4AndroidFX by doing this:
cd /data/adb/modules/ViPER4AndroidFX
5. Now rename the post-fs-data.sh to something else like post-fs-data.sh.bak or delete it by doing this:
mv post-fs-data.sh post-fs-data.sh.bak
6. You're all done, restart into system now.
NOTE: Turning off master limiter and setting it back on doesnt work. It has to be on by default all the time (probably it enables at startup and cant be toggled)
If you encounter a bootloop delete ViPER4AndroidFX inside /data/adb/modules
rm -rf /data/adb/modules/ViPER4AndroidFX
For some reason, the above method is not working for me. On latest Havoc OS build 8/12/19. First time I follow the above steps Viper still gives a pop up saying drivers not installed. I click on install again, follow the same renaming method. Second time Viper opens but driver status is abnormal.

Busybox for CrDroid Android 9

Hey, I needed a little help. I was trying to get busybox installed so I can run Viper4Android. Downloaded the busybox installer from the market and went through the typical in-App installation. Went for the reboot and got into a bootloop.
So my question is... How do we get busybox for our G7 Power? What's the preferred method?
Thanks in advance!
Their is a module on magisk for it

BusyBox is not needed. I have Viper 4 Android running on CrDroid and just have Magisk installed. Magisk root has BusyBox working already in the background.

Ok so I got it to work... Turns out I was using the "HiFi" version... Tried the regular FX and it worked like a charm.
Thanks you guys! This is why XDA exist! I've been around for a very long time and this site never disappoints!!
If a Mod could close the thread that'd be cool... Problem solved here!
