Last release I removed Mango OS due to using native DX220 as base ROM. This time I tried to port DX220 ROM version 1.11.140 using DX200 as base ROM with new technique that seems to be more stable with original Mango OS intact. 🙂

 

-Based on iBasso DX220 firmware version V1.11.140
–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
-Revamped MangoPlayer UI with improved user experience
-build.prop tweaks for better video and storage performance and improve battery life
-Audio engine optimized for only audio playback (EQ/Gaplass features work)

 

Download: iBasso DX200 Purist ROM

After first successful proper iBasso DX220 ROM port to DX200 device, I tried to find how to make Mango OS usable but it seems to be impossible and I can’t bring DX200 Mango OS back to DX220 partition image.

As a result, I decided to remove Mango OS mode completely to avoid confusion. If you prefer Mango OS too, I recommend official 1.0.6 ROM with DX220 MangoPlayer too.
