For new users, please read about PerfectDynamics 2.0 Sound Optimizations first for new improvements with Fidelizer ROMs.

 

Hi. I’m so busy with preparations for TIAV Show 2019 in Thailand at the moment and finally have some time to update Purist ROM. I’ll start with iBasso DX120 one first since it came earlier and I’ll update Fiio ROMs next.

-Based on firmware version 2.5.68
-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 DX120 Purist ROM

 

Installation Guide

1. Download iBasso FactoryTool with English UI
2. Turn off DX120
3. Connect DX120 with USB connection to computer while holding vol up button
4. Install Rockchip USB driver included in FactoryTool

If you like improvements in Purist ROM, you may upgrade to Enhanced / Advanced ROM for even better sound. Please read Portable Products for more details and you can also upgrade DX120 hardware with Fidelizer Mod project too. 🙂
