Greetings,
I tried to deliver purchased Fidelizer Pro product to your registered mail address in PayPal but it’s not delivered. I tried to search for your contact information in Facebook/Skype based on your email address but I couldn’t reach out to you too.
So, I need to make public request to ask you to send a new mail address so that I can deliver Fidelizer Pro to you at your earliest convenience.
Regards,

For new users, please read about PerfectDynamics 2.0 Sound Optimizations first for new improvements with Fidelizer ROMs.
And new DX220 ROM strikes again when I was going to update PerfectDynamics 2.0 on DX100 device. It’s a good thing for iBasso DX220 users that they keep updating frequently. I’ll update this one for DX220 first and work on DX100 next.
-Based on iBasso DX220 firmware version V1.12.149
–Yalp Store is added as Play Store’s alternative (I still keep Google 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
-MangoPlayer app has optimizations applied
-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 DX220 Purist ROM
Installation Guide
1. Install Rockchip USB driver included in AndroidTool and make sure it shows ‘Found One ADB device’ in AndroidTool software
2. Copy Official Oreo ROM firmware from iBasso to device’s storage and flash from Settings > System > Updater > Local storage
3. After successfully flashing official ROM, go to Settings > System > About tablet and tap “Build number” for 7 times to enable “Developer options”
4. Tap back arrow to enter “Developer options”, enable “USB debugging”, and press OK
5. Connect DX220 to computer with USB connection in Android mode again and press OK to allow USB debugging
6. Download Disable Verity package and run disable_verity.bat file (You may need to authorize USB debugging and run disable verity again if not reboot)
7. After DX220 boots up properly with Verity disabled, turn off device and connect with USB connection to computer while holding play button
8. Open AndroidTool, click on “Upgrade Firmware” tab, click on Firmware button and select update.img extracted from Purist ROM then click Upgrade
If you like improvements in Purist ROM, you may upgrade to Enhanced / Advanced ROM for even better sound. Please read Portable Products for more details including iBasso DX220 Fidelizer Mod project with 3 modification levels and happy listening. 🙂
Here’s a new feedback today. I received his feedback after from client purchased Fidelizer Pro from our partner Highend AudioPC who develop AudiophileOptimizer.
Hi Keetakawee. I just want to say that I am extremely happy with your product. What made even more happy was to find the cics mode in the profile.
I believe cics project inspired many passionate computer audiophiles including myself so I’d love to address proper credits to show my respect. 🙂
Here’s another feedback today. I received his feedback after assisting him in Fidelizer Pro setup with AudiophileOptimizer 3.00.
I’ve been using Fidelizer for years on Windows 10, but the combo of 8.4 + AO3 Ultimate in shell mode is easily the best I’ve ever heard. Thank you many times!
I’m glad to hear Fidelizer 8.4 update makes significant sound quality improvements with AudiophileOptimizer 3.00 and happy listening. 🙂
