  • Download the tool adb
  • Turn on your Disco.
  • Turn on your Skycontroller 2.
  • Connect your PC's Wi-Fi to the Disco (e.g. DISCO-123456).
  • Wait for the Skycontroller 2 to connect to Disco via Wi-Fi (green solid LED on the controller).
  • Use an FTP tool (e.g. FileZilla) to upload the firmware to your Disco.
    • Connect via FTP to 192.168.42.1 (no username/password required)
    • Transfer mpp_update.plf to the "/internal_000" folder on the Disco.
    • Transfer adb to the "/internal_000" folder on the Disco.
  • On Disco firmware 1.7.0 and newer: Double press the Disco's power button to enable the telnet server.
  • Open a Command Prompt (Windows)/Terminal (macOS/Linux) and Copy/Paste the following commands manually to downgrade the firmware.
    • telnet 192.168.42.1 (If you get an error under Windows, make sure the Telnet Client is installed)
    • chmod +x /data/ftp/internal_000/adb
    • sc2_wifi_ip=$(netstat -nu |grep 9988 |grep 192.168.42 | head -1 | awk '{ print $5 }' | cut -d ':' -f 1)
    • /data/ftp/internal_000/adb connect ${sc2_wifi_ip} 9050
      Repeat this commend until it returns "connected".
    • /data/ftp/internal_000/adb push /data/ftp/internal_000/mpp_update.plf /update/
    • adb shell
      • /usr/bin/pinst_trigger 1
      • reboot
    • rm /data/ftp/internal_000/adb /data/ftp/internal_000/mpp_update
  • You can restart the Disco now. Skycontroller 2 should automatically re-connect to your Disco once the firmware installation is completed.

Note: After downgrading, FreeFlight Pro might be bothering you with "UPDATE REQUIRED - Your device needs to be updated". This is because the Firmware update has been downloaded to the iOS device earlier using the App itself. The only way to get rid of this message is by clearing the App's data container.

Android: Settings -> Apps -> FreeFlight Pro -> Storage -> Clear Data
iOS: removing and reinstalling the App seems to be the easiest way...
