After DX120 Purist ROM was released for a while, I received one report from free Purist ROM user that he couldn’t flash Purist ROM and get it working. So today I went to my friend’s store and bought a new DX120 DAP to test. I opened it and then flash Purist ROM immediately and it worked fine. 🙂

 

-Based on firmware version 2.2.42
-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

 

Download: iBasso DX120 Purist ROM

 

Installation Guide

1. Extract update.img from archive and copy to root directory of micro SD card and put in DX120 slot
2. Open device Settings > Advanced > System Update
3. Wait for device to finish flashing
4. After flashing is completed, you should see Fidelizer Purist ROM boot animation indicating successful update

 

I said re-released because this release contains no changes but I decided to rebuild all packages and tested with real DX120 device again just to be sure. I also did some listening tests and I prefer “Slow” filter with “Original” sound mode personally.

There’s a lot of improvements for Advanced ROM and I also added Enhanced ROM into collection too. Please read Portable Products for more details including Fidelizer Mod project with 3 modification levels. Happy listening. 🙂

 

 

I’ve been trying to find some time to work on iBasso DX120 ROM for a while and finally I made it today. DX120 comes as Mango version only but Purist ROM can still improve its Particle audio configuration and system configuration like previous its brothers DX50/80/90. 🙂

iBasso DX200 Oreo Beta 2 ROM was released yesterday. It sounds better with fuller midrange and deeper bass with more texture. And here’s Purist ROM version.

 

-Based on firmware version Oreo 8.1 Beta 0.03.004 (Beta 2)
–Yalp Store is added as Play Store’s alternative (I keep Google Play 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 Oreo 8.1 Beta 2 Purist ROM | XMOS Firmware 1.2 Update

 

Installation Guide

First of all, this Oreo ROM comes with Verity enabled to protect system partition images. Even if you managed to flash modified system image and boot properly, those files won’t be updated and use older files from cache partition. To disable Verity, please follow the instructions below.

1. Go to Settings > System > About tablet and tap “Build number” for 7 times to enable “Developer options”
2. Tap back arrow and enter “Developer options” and enable “USB debugging”, press OK
3. Download Disable Verity package and run disable_verity.bat file (You can install driver from Official Oreo ROM package)

After DX200 boots up properly with Verity disabled, you can start flashing Purist ROM now with these steps below.

1. Turn off DX200
2. Connect DX200 with USB connection to computer while holding play button switch
3. Install Rockchip USB driver included in update tool
4. Flash Official Oreo ROM Beta firmware from iBasso with instructions provided in update tool
5. After successfully flashing official one, flash Purist ROM again

 

This firmware is still in beta stage so it’s not stable yet. If you have any issue with Oreo ROM beta, you can always go back to official 2.1.94 version and then flash Fidelizer Purist ROM thereafter for better sound quality and system performance. 🙂
