I have been struggling to upgrade the firmware of my ZD1100 to the latest firmware. At the moment, the device is on the 18.104.22.168.15 firmware. I would like to upgrade this to the latest, however no matter what I tried, it seems impossible. At the start, I tried to go straight to the last version which ended up getting stuck at 0% upgrade progress. Then I found out about the "correct" upgrade path to follow until I reach the desired latest version. However, no matter how many earlier versions I tried, even the exact next version, all upgrades get stuck at 0% with a red blinking status LED. I left it 2 times to do the upgrade overnight and it was still stuck when I woke up, 8 hours after. Any advice?
Thanks for your time in advance. Have a great day! 🙂
The thing is that the firmware that the ZD has, is so old, that I cant access it from any modern browser for security reasons. I have 3 computers and they all run Win8.1 and later OS. So I had to create a Windows 7 virtual machine and open the web UI of the controller through Internet Explorer with all older SSL settings, else the page would never open for security reasons.
Of course the laptop is on the same network. I tried with both the laptop and ZD on the main network and also by themselves without any connectivity to the router or main switch.
I will try to do both of the things you suggested, CLI upgrade and try the 22.214.171.124.9 version.
Thank you all so much for your time! I will get back to you with the results!
If you do use the browser again, make sure to add the site to the compatibility view list or upgrading the ZD from IE will corrupt the firmware. You can use IE11 on Windows 10, and it should function if you enable SSLv3.
