Fidelizer Enhanced / Advanced ROM updates for DX150 / DX200 / X5iii / X7 / X7ii

 in News

 

Portable Products

 

I posted about finishing PerfectDynamics 2.0 before attending Munich Show before. There were some progress but it’s still not considered as ready for PerfectDynamics 2.0. So I’ll release bugs fixing version instead.

As some people reported about random stability issues, I later find out that some native apps are relying on debugger and log services for I/O exception handling. Removing those services will result error beyond handling and cause system reboot.

These symptoms doesn’t happen with everyone so if you’re using Enhanced / Advanced ROM without any issue, you won’t need this update. If you have some issues that doesn’t happen with free Purist ROM, you can ask me for sending new ROM update.

I hope this will be good chance for you to consider upgrading Fidelizer software. I also made adjustments to have fidelizer.key filled automatically when you use “Order Fidelizer” button in Fidelizer software. I hope this will make order process easier. 🙂

PerfectDynamics 2.0 Sound Optimizations will be introduced in Munich 2018 AV Show

 in News

 

Fidelizer - PerfectDynamics Sound Optimizations

 

PerfectDynamics technology is device-specific optimizations for Enhanced / Advanced ROM introduced on 1st October 2017. In upcoming Munich 2018 AV Show, I’ll introduce PerfectDynamics 2.0 with iBasso DX200 and Fiio X5iii device.

During development of PerfectDynamics’ initial version, iBasso DX200 and Fiio X5iii didn’t get the better sounding version of firmware and they later improved in over time. After I tried DX150 2.9 firmware port on DX200, I feel it’s ready to take this to the next level.

Having good sounding firmware to optimize is very important because sometimes you can’t be sure whether this optimization will really improve over all performance or just compesate the flaw with firmware itself. Even now I’m still not sure that I can finish it before the show lol.

 

PerfectDynamics 2.0 Goals:

-Fix random crash and reboot in some scenarios (90% – Fixed stability issues with boot image optimizations)
-Decay, depth and imaging will be important than clarity and separation (60% – Tuning I/O optimizations)
-Transient dynamics will have improved linearity which will also reduce digital glare effect (40% – Tuning PerfectDynamics specific optimizations)
-Full sound reproduction will take higher priority than making audio sounding pure (40% – Tuning audio optimizations)

 

If I can archive all that, PerfectDynamics 2.0 will make Linux based audio performance becoming closer to Fidelizer’s optimizations in Windows. I’ll start working today on iBasso DX200 first and I hope to master PerfectDynamics 2.0 before the show. 🙂

iBasso DX150 is now added into Fidelizer Purist ROM repository with PerfectDynamics optimizations!

Fidelizer - PerfectDynamics Sound Optimizations

 

I heard the first DX150 ROM was released when I was coming back from visiting my parents during Songkran new year in Thailand. I was little worried about working on OTA ROM without factory image but I managed to make it work in the end. This won’t wipe your data too so enjoy. 🙂

-Based on firmware version 2.9.250
-Play Store added
-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)
-Bundled audio effects removed but keep main engine (Poweramp works now)

Download: iBasso DX150 Purist ROM

 

Installation Guide

1. Download Factory Tool provided by Paul http://www.ibasso.com/uploadfiles/download/FactoryTool_v1.39_DX200.zip
2. Turn off DX150
3. Connect DX150 with USB connection to computer while holding play button switch
4. Install Rockchip USB driver included in FactoryTool
5. Open FactoryTool.exe and flash ROM according to instructions provided in DX200 batch tool instruction.doc

For Mac / Linux users, please check this guide for flashing Fidelizer Purist ROM on Mac / Linux instructions.

 

I also tried flashing DX150 files on DX200 and it works too so you may expect unofficial port for DX200 soon. Please read Portable Products for more details about Enhanced and Advanced ROM and let me know if you’d like to apply Fidelizer Mod too. Happy listening. 🙂

Flashing Fidelizer Purist ROM firmware on Mac / Linux guide

 in Article

I’ve received a few requests about flashing Fidelizer Purist ROM on Mac so here’s detailed instructions to flash Fidelizer Purist ROM on Mac and Linux too.

 

We’ll use rkflashtool which is available on Windows/Mac/Linux. Windows users can also use this method to flash Fidelizer Purist ROM too though original Windows method should be easier with graphical user interface. For Mac/Linux, we’ll use Homebrew to install rkflashtool.

 

To install Homebrew and rkflashtool, open Terminal utility and type this command line below.

bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)”
brew install rkflashtool android-platform-tools

 

Now that rkflashtool is installed, you can flash Fidelizer Purist ROM by following the instructions below:

 

For iBasso DX150/160/200/220, you need to disable verity feature because Oreo ROM needs verity disabled before flashing Purist ROM so you won’t get bootloop.

 

1. You need to enable USB debugging and authorize USB debugging on Mac machine. You can read instructions in official ROM release post.

2. Run the follow commands below to disable verity. You should see notification about verity being disabled on system and vendor partition after running

adb root
adb disable-verity
adb reboot

 

Now that you finish disabling verity on device with Oreo ROM if required, you may process with ROM flashing part by following the instructions below.

 

1. Run the following commands to setup device running with loader mode.

adb reboot bootloader
fastboot reboot bootloader

2. Then enter these commands to make sure device is recognized.

rkflashtool v
rkflashtool n

3. Extract update.img file and run the following command to extract partition image files.

cd “/Users/username/Downloads” <— replace “username” with your user account name
rkunpack update.img

4. If you may see Boot folder and embbeded-update.img being extracted, please also run

rkunpack embedded-update.img

5. You should see some new image files inside Image folder. We’ll flash boot.img and system.img to for Fidelizer Purist ROM with these commands below.

cd Image
rkflashtool w boot < boot.img
rkflashtool w system < system.img

6. “premature end-of-file reached” message may appear when new image is smaller. You can reboot with Fidelizer Purist ROM using this command.

rkflashtool b

 

If you find flashing Fidelizer Purist ROM in Mac/Linux being tricky, you may use SD card firmware installation method with GUI tool. If you have any question about firmware flashing, please contact me and happy listening. 🙂
