How do I perform the emergency flashing procedure with Polyend Play?

If your device lost power during the upgrade, the SD file structure was damaged, or the firmware doesn’t boot up for any other reason, you can perform an emergency flash procedure:

  • disconnect the instrument from the power source
  • plug the USB cable into the instrument
  • press the hidden reset button on the back panel of the instrument and keep it pressed until the instrument will be turned on
  • turn on the instrument (with Power button)
  • it will automatically flash with a randomly picked firmware .ppf file from the SD card Firmware/ folder
