iBasso DX100/HDP-R10 Purist ROM version 1.4.2 released!

Fidelizer - DX100 Purist ROM


I was told new DX200 ROM is out now but allow me to release this first. In my early days of Android ROM optimizations, I got a chance to try optimizing DX100 ROM for my client once but couldn’t get the optimized ROM working due to my inexperience.

I recently got another chance to try on iBasso DX100 firmware again. Now I know more about Android and Linux so I can optimize both boot and system image without corrupting it. DX100 is quite slow with Gingerbread and Fidelizer Purist ROM helps a lot.

After modifying DX100 firmware, the client himself told me he’ll apply Fidelizer Ultimate Mod for completed hardware upgrade next. I also modified AK380Cu last week and have few more DX200, AK380Cu and Opus#2 to work on so this will take a while. 🙂


-Based on firmware version 1.4.2
-build.prop tweaks for better video and storage performance and improve battery life
-Audio engine optimized for only audio playback (EQ/Gaplass features work)
-Bundled audio effects removed but keep main engine (Poweramp works now)
