Yesterday I received a message asking why I haven’t updated Fiio X7ii ROM to version 1.0.3 yet. I was occupied with many projects and didn’t notice Fiio X7ii ROM until yesterday. Since this ROM came out before DX200 2.7.188, I decided to publish Fiio X7ii ROM today with the following updates.

-Based on official Fiio X7ii 1.0.3 ROM
-Deodexed
-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)
