After trying to update firmware from v1.1.1 to v1.2 the X1800 mixer is unusable. Something was going wrong during update and now all lights starting in the top left hand corner moving to bottom right hand. The update was done from my MBP with sleep mode turned off.
Tested to re-install the firmware several times with no success. This is tested with windows and Mac computers several times with the same result. The updater program sends data and I have waited hours after it finished before manual restart of mixer. It looks like the mixer stops to receiving data after a few seconds and the mixer shows the message “Restart X1800” in the display.
This is the result: 1. I Press the buttons BACK + FX CUE + TAP 2. I Power on the X1800 while holding the 3 button combination above. 3. The display will show “ Update Firmware?” - OK / CANCEL ” 4. I Select OK 5. The displays shows ”Update, DSP Recover” 6. After a few seconds the display shows ”DONE, RESTART X1800”
Also tested to do factory reset but the mixer just freeze after that.
And yes I have done firmware updates before on the unit and are very familiar with this type of operations as I have worked as soft/hardware designer/tester in many years with similar and more complex systems.
I have filed a support request and is awaiting response from Denon DJ as my mixer is unusable.
