And last but not least, Fiio X7 now has Purist ROM updated to version 3.3.5. This ones doesn’t have ROM deodexed too so it won’t sound brighter than stock ROM as well. I’m also working on ROM updates to resolve specific issues in DX200 and it’ll be updated soon.

 

-Based on firmware version 3.3.5
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-build.prop tweaks for better video and storage performance and improve battery life
-bundled audio effects removed but keep main engine (Poweramp works now)
