    Fiio X5iii Purist ROM version 1.2.0 released without wiping data required!

     

    Fidelizer Mod

     

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

     

    I received information about Fiio launching big update for Fiio X5ii, X7 and X7ii at the same time. As I’ve been busy with many projects including Fidelizer 8 updates so I can release only one at time and I’ll start with the most popular Fiio X5iii first. 🙂

    After launching firmware updates for a while, I realized most customers are returning users so wiping data again won’t be necessary anymore. I also tuned PerfectDynamics on Enhanced / Advanced ROM to reduce bright sound with stock hardware on some headphones.

    -Based on firmware version 1.2.0
    -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)
