How to Perform a Drag & Drop Firmware Update

Follow these steps to flash new firmware to the MYND Speaker.

---

1. Power On the Unit

• Turn on the device.
• Wait for the power-on sound icon.

---

2. Enter Update Mode

• Press and hold Power + Volume Minus for 8-10 seconds.
• Release when the Power LED flashes red periodically.
• The unit stays in update mode until the update is complete or a hardware reset is performed.
  _{To reset: Hold Plus + Minus for 10 seconds. This is a hardware last-resort which will slowly charge up a capacitor if plus and minus are pressed at the same time. After the capacitor is charged, the MCU reset line gets pulled low.}
