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??
Hi karl and thanx for the reply.
I allready have the firmware 188.8.131.52.154. and it should be possible to upgrade the ZD 1200 if the firmware is below the factory default.
i have tried to uploading via the "Restore" button in the GUI and it just loads and loads......maybe i should give it more time (i gave it around 15 minutes).
So the real question is - is it doable to downgrade firmware, when the factory default is higher than the firmware i try to install.
184.108.40.206.154 is the last version which supports 7363.
Downgrading directly from 10.x to 9.12 will factory reset the ZD and you have to reconfigure it.
Factory resetting the ZD will not downgrade the firmware, you have to downgrade it manually from GUI or ZD CLI.
