What can I do if my FX150 doesn't work after the firmware update?
We found that just turning the unit on normally and then sending a special MIDI-OX firmware update, would recovered the unit. To do this, please download MIDI-OX.
To do this update please refer to this FAQ on how to configure MIDI-OX.
If this fix doesn't work for you and the unit lights up but is unresponsive, please contact support.
