Hi.
The firmware 3.32 upgrade to my 2018 faderport fails also with many blinking lights. I tried different ports on my mac, etc., but so far no joy.
To reset your faderport to factory, power off the faderport. Hold down the PREV button and power on the faderport. The READ button will flash. Press that and you will be reset. Power cycle the unit and you should be fine.
