Firmware Flasher

Flash firmware directly to your Terrarium or FunBox pedal from the browser. No software to install — just USB and Chrome.

Your browser does not support WebUSB. Please use Google Chrome or Microsoft Edge on desktop to use this tool.

IMPORTANT: Disconnect your pedal from its 9V power supply before flashing. Only the USB cable should be connected to the Daisy Seed during the flash process. Having both USB and 9V power connected at the same time can damage the Daisy Seed.

STEP 1

Select Platform & Firmware

Choose your pedal platform, then the firmware to flash.

STEP 2

Connect Daisy Seed

Put your pedal into DFU mode (hold both footswitches while plugging in USB), then click connect. A browser popup will appear — select “DFU in FS Mode” from the list and click Connect.

STEP 3

Flash

Write the firmware to your pedal. This may take a couple of minutes — do not disconnect during the flash.

How to enter DFU mode

Hold both footswitches down while plugging in USB power. Both LEDs will blink to confirm DFU mode.

Hold down both footswitches on the pedal.
While holding, plug in the USB cable to power on the pedal.
Both LEDs will blink 3 times to confirm DFU entry.
Release the footswitches.
Click CONNECT USB above. A popup will appear — select “DFU in FS Mode” and click Connect.

Alternate method: If the pedal does not have this firmware yet, open the enclosure and use the Daisy Seed buttons — hold BOOT, tap RESET, release BOOT.
