 in News

 

DX200 - Purist ROM

 

First of all, I’d like to inform you that there’s new changes in kernel version 2.9 that made some usual optimizations I put on didn’t work anymore. I made some adjustments to fix this issue and released it with testing from my environment.

However, some cases like Samsung 256GB micro SD card having massive collection like 20,000 songs won’t work smoothly. With help from understanding clients who tested my ROM and loan his unit for testing, I can finally make a stable release.

In this release, I’ll also add instructions to flash factory image version 2.1.94 and wiping data too. You can skip optional steps if you don’t have any issue.

Fiio X7ii Purist ROM version 1.0.6 released with bright sound signature fixed

 in News

 

Fidelizer Mod

 

I planned to release this yesterday but I was busy with attending headphone cable contest event in Thailand as guest. Fidelizer Purist ROM for Fiio X7ii is now updated to version 1.0.6 without deodexing applied so sound signature won’t be brighter anymore.

Fiio’s Purist ROM isn’t deodexed anymore. I was little bummed about it. But people who don’t apply Fidelizer Mod will be more happier and Fidelizer Mod users can still get deodexed ROM. The total happiness in the world increased so happy listening. 🙂

Fiio X5iii Purist ROM version 1.2.1 released – Bright sound signature is now fixed with as Odexed ROM

 in News

 

Fidelizer Mod

 

Sorry for the long delay. I was visiting my parents since last month and I didn’t bring my ROM cooking materials with me. I only got back to my place few days ago and started cooking new Fiio ROMs as soon as possible.

As some people reported and mentioned in forums about Purist ROM sounding brighter than stock ROM, it was caused by de-odexing ROM which is a common practice for ROM cooking with ART runtime.

Odexed file is compiled as Dalvik byte code so app will run through Dalvik VM. De-odexing ROM will allow ART runtime to run app natively which also improve transparency and resolution in audio too.

However, opamps used in Fiio devices tend to sound brighter so de-odexing will make those characteristics more revealing too. I will publish odexed ROM so it won’t change sound signature on stock unit and use de-odexed ROM for Fidelizer Mod version.
