⚡Firmware reset (Nuke) — TouchMe, Playtron, and Biotron

The Nuke reset completely wipes and reinstalls the firmware on your device. Use it when:

• The device is not recognised by your computer at all.
• The device appears as the RPI-RP2 drive but not as a MIDI device.
• The device behaves unexpectedly after a failed firmware update.
• Support has asked you to do a full reset.

⚠️ USB-C devices only (2026 models and later). This reset method requires a USB-C port. Older Micro-USB models do not support this process. Check your device — if the port is USB-C, you can use this guide.

First — try the simple update

1. Open the settings page for your device in Brave or Chrome.
   • TouchMe: settings.playtronica.com/#/touchme
   • Playtron: settings.playtronica.com/#/playtron
   • Biotron: settings.playtronica.com/#/biotron
2. Plug in the device with USB-C and click "Update Firmware". If the RPI-RP2 drive appears automatically, skip to step 4. If the drive does not appear, use the manual Nuke below.
3. Follow the on-screen instructions to put the device into update mode.
4. Upload the latest firmware. The device reboots automatically. After the reboot, the device appears as a MIDI device, not a drive.

Manual Nuke (if the simple update does not work)

You will need a paper clip, tweezers, or a short piece of wire, and your USB-C cable.

1. Find the BOOT pins on your device. The BOOT pins are two small metal contacts on the PCB, usually near the USB port. Check the silkscreen label on the device or the diagram at settings.playtronica.com.
2. Short the BOOT pins. Touch both pins at the same time with a paper clip. Hold the connection.
3. With the pins still shorted, plug in the USB-C cable.
4. Wait for the RPI-RP2 drive to appear on your computer. Only release the pins after the drive appears. The window is brief. If you miss it, unplug and try again.
5. Release the pins.
6. Download flash_nuke.uf2 and drag it onto the RPI-RP2 drive. The device disconnects and reboots. This wipes the firmware completely.
7. Open settings.playtronica.com/#/[your device] in Brave or Chrome and click "Update Firmware". Upload the latest firmware. The device reboots again and appears as a working MIDI device.
