After successful ports of iBasso DX220 ROM to DX150 and DX200 devices, it’s finally time to add Purist ROM optimizations to actual DX220 now. I tested with real iBasso DX220 DAP before applying Fidelizer Mod optimizations to confirm that it worked fine.

 

-Based on iBasso DX220 firmware version Oreo 8.1 V1.09.092
–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)

After launching an update with new MangoPlayer app from iBasso DX220, some who use 3rd-party apps told me they want DX220 ROM port if possible so I decided to port the whole ROM instead. Mango OS is still DX200 version because DX200’s display isn’t compatible.
