Checklist

Before You Start

A few minutes of prep makes the rest painless. Have these ready and you are good to go.

What you need

  • A computer (PC or Mac) with ADB (Android Debug Bridge) installed
  • A high-quality USB-C cable
  • Approximate time: ~10 minutes
The Install

Three Steps to Anantar Ultimate

Follow them in order. The installer does the heavy lifting — you just authorize and wait.

1

Prepare your device

This lets your computer talk to your player. You only do it once, and there's nothing to break. Do all three parts below on the player (DX340 / DX340Max / DX270) in Android mode, in order.

Unlock Developer Options

Settings › About phone › tap Build number 7 times

You'll see "You are now a developer!" when it works. Enter your PIN if asked.

Turn on USB Debugging

Settings › System › Developer options › USB debugging: ON

"Developer options" only shows up after the first part. Tap OK on any warning — it's safe.

Connect & allow

Plug in the USB-C cable › tap Allow on the pop-up

Tick "Always allow from this computer" first. No pop-up? Re-plug the cable or unlock the screen.

💡 Tip: Use a real USB-C data cable straight into your computer — a charging-only cable or a hub won't work.

2

Download the installer

⬇ Download Anantar-Ultimate-Installer.zip

⚠ Chrome may warn that the file "can't be downloaded securely" and try to discard it. That's expected — the installer is safe. Click the ⋯ next to the warning and choose Keep.

Extract the ZIP to any folder. Keep Wi-Fi connected during the install so the device can fetch what it needs.

3

Run the installer for your OS

Open the file that matches your computer:

🪟 Windows: Windows-Anantar-Ultimate-Installer.bat 🍎 macOS / Linux: MacOS-Anantar-Ultimate-Installer.command

macOS Tip: If it fails, open Terminal → type chmod +x → drag the .command file in → press Enter → try again.

Windows Tip: If the installer can't find ADB, download platform-tools, extract it, and place the platform-tools folder inside the installer folder. Then run the .bat again.

Follow the on-screen prompts. If Magisk asks for "Additional Setup", tap OK. Wait for the ANANTAR ULTIMATE logo in the terminal — the device then reboots automatically.

↑ Updates

OTA Updates — No PC Required

Once installed, future versions update straight from the device. No computer needed.

Heads up: for the current V9.6 release, grab the build from Discord. In-app OTA updates are coming soon — the flow below is how they'll work.
↑

Update from the Magisk app

Open the Magisk app, go to the Modules tab (bottom right), find Anantar Ultimate, and tap Update.

Wait for "Finished" or "Success" — done.

Advanced

Optional Power-User Tweaks

Everything below is optional. Expand only what you need — your install already sounds great without it.

Want even better sound? Format your microSD as EXT4 (advanced)

Switching your microSD from exFAT to EXT4 is one of the most impactful changes you can make for audio quality.

Why it helps: EXT4 is handled natively by the Linux kernel, removing the exFAT FUSE/software translation layer. That lowers CPU overhead and electrical noise — expect roughly a 10–15% SQ improvement: a larger soundstage, better 3D positioning, and more micro-detail. Anantar Ultimate provides full native EXT4 support in MangoOS.

Format via ADB:

  1. Back up your microSD data first — formatting erases everything on the card.
  2. Connect the DX340 / DX340Max / DX270 via USB and open an ADB shell.
  3. Grant root (shell permission) access.
  4. Run the formatting command via ADB Shell to format the card with optimized parameters for high-fidelity audio playback.
  5. Wait for completion, then reboot the device.

Limitations & how to revert:

  • EXT4 cards are not directly readable on Windows/macOS card readers — transfer files via USB/ADB instead.
  • To switch back: Settings → Storage → Format as portable, or use ADB to reformat to exFAT.
Uninstall / A-B test

Uninstall completely:

  1. Set your Boot Profile to "Off" first.
  2. Open the Magisk app → select "Uninstall Magisk".
  3. The device reboots and becomes unrooted.
  4. Uninstall the Magisk app.

💡 If sending the device to iBasso for service, factory reset after unrooting.

A-B test (disable / enable):

  • Disable: set Boot Profile to "Off" → Magisk → Modules → Disable Anantar Ultimate → reboot.
  • Enable: Magisk → Modules → Enable Anantar Ultimate → reboot, then re-enable your favourite Boot Profile.
Upgrade firmware without data loss
  1. Download the OTA firmware ZIP from the iBasso website.
  2. Run adb reboot recovery.
  3. Select "Apply update from ADB".
  4. Run adb sideload DX340_full_ota_x.xx.zip.
  5. Reboot, then reinstall Anantar Ultimate.

⚠️ Windows 11 has issues with fastboot — use QFIL or ADB sideload instead.

Recovery

If Something Goes Wrong

Don't panic. Every scenario has a documented path back — from a stuck boot to a full reflash.

You can always recover. The DX340 / DX340Max / DX270 is a Qualcomm device with a documented recovery path, so even a hard brick is fixable. Start with the soft-brick steps below; reach for QFIL only if the device won't boot at all.
Soft Brick Recovery
  1. Turn the device OFF.
  2. Hold Bottom Side Button + Power Button together.
  3. When the iBasso logo appears, release Power (keep holding the Side Button).
  4. Navigate to "Recovery Mode" → confirm with Power.
  5. Select "Wipe data/factory reset" → confirm the factory data reset.
  6. Select "Reboot system now".
Hard Brick Recovery (QFIL)

The DX340 uses a Qualcomm SoC, so you can flash the entire firmware via QFIL (Qualcomm Flash Image Loader).

What you need:

  • QFIL tool
  • USB-C cable
  • iBasso full firmware package
  • Qualcomm EDL drivers

Steps to flash (high-level):

  1. Enter EDL mode.
  2. Connect the device.
  3. Open QFIL.
  4. Select the firmware.
  5. Flash.
  6. Reboot.
