Create Your Own Theme

So You Want to Mod the Echo Mini?

Creating a custom theme means modifying the device firmware image. It's not as scary as it sounds — the community has built great tools to make the process accessible. Follow the steps below and you'll be building your own theme in no time.

Figma Design Template

Community member u/KernelCorns — who also shares themes in the catalog — has created a Figma design file that contains images from the actual Echo Mini software. This makes it much easier to start designing your own theme visually before modifying the firmware.

What You'll Need

  1. An Official Firmware Image (.IMG) from Fiio, or an existing community image.
  2. The Flame Ocean modding tool by Takobin (also available as online tool ).
  3. A guide explaining how the entire thing works — check the firmware modding video tutorial .

How to Transfer the Firmware

Once your theme is ready and packed into an .img file, copy it to your device following these rules:

  • Use a computer — not a phone. You need to be able to verify the file size after copying.
  • Verify the firmware size is fully intact — not a single byte less than the original. Check the file size on the device matches the source file.
  • Do not rush. Wait for the transfer to fully complete before disconnecting. The Echo Mini's hardware is not robust.
  • Wait at least 20 seconds after the copy appears done before unplugging. A partially copied firmware will brick the device immediately.
