Cranborne Audio Carnaby HE2

Download the .uf2 firmware file from the Carnaby HE2 product page. Quit the Carnaby HE2 Control software. Connect the unit via USB-C and power on. Press and hold the Dual Mono and Mid/Side buttons simultaneously for 3 seconds until all LEDs go off (except power). The device appears as a USB drive — drag and drop the .uf2 file onto it. Do not disconnect until the update completes. Note: the update resets parameters, LED brightness, and network settings to defaults.
