I have rebooted, reset the unit to Factory default, tried loading 9.4.2.29, 9.4.3.0.16 and onwards.
The system accepts the Image and directs me to a progress page but sits on 0% and goes nowhere else. After about 15-20 minutes nothing changes so I have to reboot and try again.
I have recently upgraded our in-house ZD1100 all the way up from 9.1.0.0 to 9.6.0.0.267 without an issue.
I have used IE, Firefox and chrome with the same result.
Am I just being impatient and it takes longer than 15-20 minutes sometimes?
