It’s been a while since last DX220 ROM release. This time they added some compatibility improvements with AMP9, DSD512 and some others. Hopefully it will help on DX150/DX200 port I’m going to bake later too. For Enhanced / Advanced ROM, I kept Google Chrome for web app now. 🙂

 

-Based on iBasso DX220 firmware version V1.13.202
–Yalp Store is added as Play Store’s alternative (I still keep Google services for those who want to install Play Store through other means)
-Apollo – Fidelity Edition from https://forum.xda-developers.com/android/apps-games/apollo-music-player-fidelity-edition-t3038629 included
-MangoPlayer app has optimizations applied
-build.prop tweaks for better video and storage performance and improve battery life
-Audio engine optimized for only audio playback (EQ/Gaplass features work)

Hi guys. Fidelizer Purist ROM update for iBasso DX120 ROM version 2.9.121 is out now. It’s a bit confusing to choose between 2.9.121 and 2.9.122 release but they both are actually the same ROM so I believe official version is 2.9.121 one. 🙂

-build.prop tweaks for better video and storage performance and improve battery life
-Audio engine optimized for only audio playback (EQ/Gaplass features work)
