I am trying to upgrade one of my Zone directors. It is a ZD1112 with no AP's attached. Current firmware is 184.108.40.206.15. After the system has uploaded the firmware the dialog changes to 'restarting', the status led flashes red; on and off, and that's all, I reset it after 2,5 hours. I know it's not the firmware as II successfully upgraded the other two ZD100's that I have yesterday using the same img file. Is there a way to firce the ZD100 into recovery mode so try and manually delete the current firmware so that I can try reloading it directly?
