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. 🙂

iBasso DX50 / 80 / 90 Purist ROMs update with Equalizer / Gapless returning for Advanced Purist

 in News

Portable Products
Last week I received bug report from iBasso DX90 user that player sometimes stop playing next song. It didn’t happen during the tests because it often happened after 10 songs played, sometimes after second loop of the album.

I spent the whole week investigating why this happened and I found that removing Equalizer and Gapless on Advanced Purist ROM will trigger this bug. To resolve the case, I brought back those features in Advanced Purist but kept audio effect engine removed.

iBasso DX50/80/90 will contain the following features as below:

-Based on most recent version from official iBasso website
-System font was replaced with lighter version of Nimbus font
-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 DX50 – DX80 – DX90 Purist ROMs

Installation Guide

1. Extract update.img from archive and copy to internal storage (or the micro SD slot 1 for DX80)
2. Open device Settings > Advanced > System Update
3. Wait for device to finish flashing
4. After flashing is completed, I recommend choosing Slow filter

 

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

 

There’s a lot of improvements for Enhanced / Advanced ROM with PerfectDynamics Sound Optimizations. Please also check Portable Products for more details about ROM upgrades and hardware modification.

Fidelizer Upgrade Program – Extending 2,800th purchase offer to 21st February 2018

 in News

 

Fidelizer Pro

 

Hello everyone. After launching Fidelizer Upgrade Program for a while, I noticed there’s only Fidelizer Plus license and I found it a little strange since past few days. I thought maybe they want to try Plus version first.

Today I was informed that some customers could’t purchase Fidelizer Pro license at all so I checked up the website and found Pro section has torned up options. I suspect it was some parts of auto correction bug with new WordPress update.

After screaming to my own stupidity for a while, I’ve fixed this bug in Fidelizer Upgrade Program and Fidelizer Pro purchase is working fine now. To compensate for this error, I’ve extended the purchase offer time as below.

 

Fidelizer Plus: US $39.95 —> $34.95 (Expired)
Fidelizer Pro: US $69.95 —> $59.95 (Expired)

 

This offer will last until 21st February 2018. Discount rate is the same as purchasing Fidelizer software again so new customer and returning customer will get the same price. You may order again anytime and receive partial-refund as discount later after this campaign is over.

I truly apologize for the inconvenience with Fidelizer Upgrade Program. I’ll be more careful from now on to not repeat the same mistake again and thank you so much to everyone who reported me this issue today. 🙂
