Step 2: Set selinux to permissive by flashing the permissive patcher, a flashable version is available here on XDA https://forum.xda-developers.com/and...droid-t3506338
Step 3: Install The SELinux Switch by xda developer Ibuprofen. This app can be found on XDA labs. Once it's installed set SElinux to permissive in the app https://forum.xda-developers.com/and...witch-t3656502
Step 4: Install viper4android apk of your choice. I used the OP version. Open the app, and grant magisk root permission and then enable the master limiter of your choice... speaker, headphones etc.
Step 5: Enjoy!
To be noted if you are using stock rom that uses dolby (stock) or audioFX (lineage) or otherwise, turn these apps off first to ensure no conflicts with viper4android. If your android settings enable you to choose a default equalizer, make sure Viper is selected. I also have these files mentioned above. If you need them let me know. Best of luck!
