I cant access the jumpers, mine is mounted on a MM pedestal under a fully loaded MM UFO cube. I'm not redoing all my cable management and refilling everything just to flash the firmware.
So there is no other way to flash it than unmounting it and putting jumpers on (which were not sold with the unit, and i dont have any left since the 1980's) ? I didnt flash yet, and the unit is working by itself (i can access the UI since it's a Pro version) - its just the Aquasuite which is unusable.
I wish i had known this before i assembled everything.
