YOU MUST DISCONNECT YOUR MIDI CABLE WHEN UPDATING FIRMWARE VIA USB OR BLUETOOTH
It's fine to keep midi connected when using h9 to edit presets etc, but not to update the firmware, I wish support had told me this upfront, seems obvious now.
Yes, the communication is through MIDI over Bluetooth/USB, so connected MIDI cables might interfere with the update. I'm sorry to hear what you've experienced.Show More...Show Less...
