[Tips] [GUIDE] Install Dolby Atmos & Viper4Android via TWRP

Since I've been using Pixel Experience, I never moved to a different ROM since battery backup and performance is awesome! Only thing missing was music mods. You can test this guide in stock and other custom ROMs as well and feel free to provide feedback in the comments. Now, onto the guide!



  • Assuming your on your ROM's homescreen, reboot to recovery to get in TWRP.
  • Flash via TWRP. It should start the AROMA installer.
  • Choose Viper4Arise in the AROMA installer, pick, install Viper profiles, skip all other options, remove deep buffer.
  • Reboot to system. Viper4Arise should be installed but it will force close. Long press the app, and choose disable. We will disable this app as we will use a newer version.
  • Install latest Viper4Android app via the link or the XDA Labs app.
  • Turn on the options you want to choose. Play your music with your favorite music player. Turn off/on the master power. Processing should work after.
  • Reboot to recovery again to return to TWRP.
  • Install Dolby Atmos Axon 7 port provided in this XDA thread.
  • Once flashing is done, reboot to system.

Here is Viper4Android with processing working!

And here is Dolby Atmos properly working!

Voila! Dolby Atmos should work side-by-side with Viper4Android! Hope this helps and report if it works for you!

This has been tested on the following ROMs:
- Pixel Experience (4/8/18 build)
