Hi everyone. It’s been a about a week after Fiio releasing major ROM update on X5iii/X7/X7ii devices. I spent last few days finalizing and optimizing X7ii ROM first because it has separated Japan release and there’s issues with Fiio Music app having new update pushed thereafter too.

Now the work is done. I also included new Fiio Music app update with optimizations I usually apply on Advanced ROM. it wouldn’t hurt to include optimized music app for Purist ROM users. New UI looks really good and smoother with optimizations applied.

This time I’m releasing both global ROM (1.0.7) and Japan ROM (1.0.8 JP) together. I recommend to flash official ROM first before flashing Purist ROM version to get the same partition alignment. Cross flashing will make device unbootable and may corrupt its data.

 

-Based on firmware version 1.0.7 / 1.0.8 JP
-Fiio Music app version 1.0.8.013003 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)
