I’ve been receiving requests about Fiio X7ii Purist ROM for a while. As we learned past experience that first release will often come with bugs to be resolved so I waited until version 1.0.1 shipped out first then Purist ROM will follow and it’s finally here.
-Based on official Fiio X7ii 1.0.1 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)

I also added a quantum leap optimizations in Advanced ROM for the first time with Fiio X7ii releases. I’ll officially elaborate about these big improvements in details later. Please also check Portable Products for more details about ROM upgrades and hardware modification.
