[GUIDE] [VIPER4ANDROID] [Android 8.0.0]

[Thargorsson]

Hi everybody,
I want to show you how to install Viper4android on your phone running developer preview 3 or later with Android O.

IM NOT RESPONSIBLE FOR ANYTHING THAT HAPPENS TO YOUR PHONE!!

First download the zip from Androidfilehost or from below.

Zip
https://www.androidfilehost.com/?fid=673368273298967857
Busybox
https://www.androidfilehost.com/?fid=961840155545578665

Extract it to any folder, you will have two files now, a Viper4android App and a flashable Viper4android zip.
Reboot into recovery and install the zip, I also recommend a custom kernel like the Jolla Kernel which already has Android O support for loudness control (for my Nexus 5X).
Boot normally install BusyBox and launch Viper4android.
Select install drivers, grant root permission and wait until it is installed.
If a IO Error occurrs don't worry it'll work anyway.
Reboot and open any file manager.
Delete the Viper4android folder in "/system/priv-app".
Delete "/system/vendor/etc/audio_effects".
Install Viper4android app you downloaded before.
Reboot once again and open Viper4android - driver are working now.

Tested on my Nexus 5X with Android 8 developer preview 3.

Leave a like if it helped.

Aha I've only tested with latest supersu that might be the problem.
Try the 2.82 version.

Good. btw did you deleted the old Viper4android folder and installed the new app as user app? And changing enforce to permissive also fix some problems.

Hows the exact process you wen through?

 

[jbirdyRazr]

I have not implemented yet. Was wondering if anybody else had. Now using SuperSu 2.82-SR5 and TWRP 3.1.1.0. Now that TRWP works now without having to fastboot, I will try this mod. If I get it working I will let you know.

Ah k

I went through the entire procedure including deleting the system app and installing the io fix version.
The app tells me that drivers are working but i there is no difference in sound.
Turing Master power on and off dosen't seam to make any diffrence. What is going on?

Which device, Rom and kernel? And also which music player are you using? Also try enabke developer options in Viper and select disable selinux and/or enable FX compatibility mode.
