Zonedirector 1100 firmware upgrade issue

[heart_l3ss]

Hello,

I have been struggling to upgrade the firmware of my ZD1100 to the latest firmware.
At the moment, the device is on the 9.6.1.0.15 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! 🙂

Update:

I tried both version 9.7.2.0.9 and upgrading through CLI, with no success.
Same issue with 9.7.2.0.9 that got stuck at 0% and CLI documentation is unfortunately available to premium support users, which I am not and have no experience in stuff like this. Any guide would be appreciated.

@Mitchel Axtell, I have already tried what you mentioned and IE on Win10 still gives me the error that the website is using a protocol no longer supported. I think they have strictly forbidden the access to such pages on the latest versions of the OS and browsers.

Hi There,

It is unfortunate to hear that upgrade failed even through the CLI; All CLI related commands and steps were detailed in the video link I shared in my first comment. I am suspecting it to be a memory related issue which need a cleanup. I would recommend you to contact our support hotline for further help.

I already tried to contact support, but as the product has reached EOL and I do not have any support contract, I guess it won't be of much help. Are there any simple guides on connecting through CLI to the device itself using putty?

Yes, use SSH (TCP:22) to the ZD IP address, login with admin credentials.  Type Help to see commands available.
