I just bought a new ZD1200 and i would like to install 9.xxxx on it so i can use my zone flex 7363 with this unit.
My problem is that it comes by default with 10.1.0.0 build 1515. I have tried to make a factory reset via the browser interface and via holding down the F/D button on the hardware for about 15 seconds and it still shows up the 10.1.0.0 firmware.
How do i downgrade the firmware??
