Hello CrsMthw,
I tried to install viper4android with your method on my SM-920C Note 5 - ROM Nougat NN9 (Android v7.0) but the driver seems not working.
So I tried to uninstall them via the app menu and reboot system but when I open the app again v4a doesn't prompt me to install the drivers, they seems installed but not working.
I've Magisk v14 installed.
Any suggestion? Ty in advance


nevermind, I managed to get it working, my kernel was set to "enforced", setting it to "permissive" did the trick

Can you share how you set the kernel to permissive?

flashed the permissive stock Kernel from the NougatNN thread:

this kernel come with SuperSU so I've removed it from the settings of the app (restoring the stock boot.img) then I've flashed this script to be sure SuperSu is fully removed, after this I've installed via recovery Magisk Beta v14.3.

So here you go!! Also works with my Dolby Atmos!

Tested devices:
- S6 edge+
- Note 5


- Samsung device
- Nougat rom (N-lite V3 rom users, please wait for V4 rom. Pre-installed busybox on V3 interferes with viper driver installation)
- Rooted by Magisk (Dolby does not need root. Only viper needs root by magisk)

Installation instructions:
- Flash attached viper zip file and UPDATE zip file in TWRP. Users already using this mod, please see update instructions below.
- Reboot
- Install Busybox by Meefik here -
- Open Viper4android app and install drivers if it prompts.
- Enjoy!! Flash DolbyAtmos zip if you want

Update instructions:
- Uninstall Viper4android drivers from the menu in Viper4android app.
- Flash the update zip.

DolbyAtmos thread here:

Download Mirror:
MEGA - Main zip
MEGA - Update zip

Thanks and Credits:
- @CaptainTiiti for the countless hours of support and guidance and motivation, without him, this project would have never made it here
- @topjohnwu for the magisk stuff
- The developers behind Viper4Android
- @worstenbrood for the original dolby atmos mod
- @gtaelbordo for the kindness and support, and for the icons of DolbyAtmos

Hope you like it. Leave a Thanks if you do.

See you soon!
