For new users, please read about PerfectDynamics 2.0 Sound Optimizations first for new improvements with Fidelizer ROMs.

 

Hi. I’ve finished TIAV Show now and I started Fiio ROM updates right away. Here’s Purist ROM updates for Fiio X7ii including Japan version.

I recommend to flash official global ROM (1.1.0) or Japan ROM (1.1.2 JP) before flashing Purist ROM version to make sure you get the same partition alignment. Cross flashing will make device unbootable and may corrupt device’s data.

 

-Based on firmware version 1.1.0 / 1.1.2 JP
-Fiio Music app is updated with Fidelizer optimizations
-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)
