Fiio X5iii Purist ROM version 1.2.5 V2 released with jkbuha’s kernel and improved PerfectDynamics 3.0!

 

Fidelizer - PerfectDynamics Sound Optimizations 3.0

 

For new users, please read about PerfectDynamics 3.0 Sound Optimizations first for new improvements with Fidelizer ROMs.

 

It’s been a long while since last update of Fiio X series and I haven’t finished rolling PerfectDynamics 3.0 yet due to finalizing the improvements on legacy devices. There’s stability and sound signature to be addressed.

Finally I managed to replicate similar improvements on Oreo ROM with octa core. I tuned background tasks running on FIFO similar to R2R design and that can provide more linear sound and transparency with right tuning.

I also improved deodexing and re-basing ROM again from scratch to make sure it will be glitchless and updated Fiio Music with latest version V3.0.3 with new custom kernel from jkbuha. I’ll roll new updates for X7 and X7ii later soon.

 

-Based on firmware version 1.2.5
-De-odexed for better ART runtime optimizations
-PerfectDynamics 3.0 Sound Optimizations applied
-Kernel is replaced with jkbuha’s custom kernel
-Fiio Music app V3.0.3 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)
