How to prepare your Mercury V1 for updating

Step 1 of 3

Connect and enable update mode

Hold down the BUTTON on your Mercury, and while holding it, briefly press the POWER button. Your Mercury is now in boot mode and ready to receive firmware.

The status LED will be off — that's normal in boot mode. The charging LED may still light up, which is fine and just means the USB connection is good. The output LED may also be illuminated, which is also normal — leave it as-is and continue.
