how to go back to version 1.1.50.39 firmware from version 2.0.0.1 Insight-ready firmware

Welcome to the community! :)
did someone has been able to go back to firmware version image 1.1.50.39 on a GS724TPv2 that has been upgraded to version 2.0.0.2 ?
There is no GS724Tv2 firmware v2.0.0.2. I believe you referring to firmware v2.0.1.2. As far as I have checked, there is no issue logged for the GS724TPv2 with firmware v2.0.1.2 as per you have described in your initial post.
My company bought a GS724TPv2 managed switch for a PoC and everything was fine with version 1.1.50.39 and below.
Unfortunately, the switch has been upgraded to Now with 2.0.0.1 firmware, it relentlessly generate SSDP traffic on one port, which is connected to a firewall's interface. Naturally, the firewall is blocking + dropping such traffic. Security team (managing the Sec Infrastructure and firewalls) are on my back because of all alerts and logs filling that switch is generating :-( The switch has been relocated to a small office LAN segment for the time being. It is less than a year old.
There might be other changes made besides the firmware update that might trigger the problem such as change in the settings of the GS724TPv2 or additional devices connected within the existing network.
It would be best that you download the tech support file of the GS724TPv2. Then, open a support ticket with NETGEAR Support here at anytime in order for the tech support file to be analyzed why the GS724TPv2 generated SSDP traffic on one port that is connected to a firewall's interface.
Kindly read pages 387-388 of the GS724Tv2 user manual here on how to download the tech support file.

Well possible, the Insight-enabled firmware does announce itself byUPnP (SSDP) and Bonjour to the network. Is there any Web UI control to enable/disable these?
I think too it is the insight firmware that generate that traffic. Unfortunately, there is no option in the webGUI to disable that.
Thanks for your input.

Welcome to Netgear community, SSDP traffic is designed to support Insight-enable on v2.0.1.2, and no option to disable it on GUI, multicast less than 10 packets per sec, so it's harmless when device working in standalone or Cloud mode, it shouldn't cause device flooding or reload.do you see anything else broken beside uplink port traffic light LED flash?
Can I know your topology in more detail? how many other devices are connected?
Internet -- FW -- GS724TPv2 --any additional devices?
v1.1.50.39 is transition image from non-insight support (v1.1.x.x) to Insight-enable image (v2.0.x.x), upgrade path should be v1.1.x.x -> v1.1.50.39 -> v2.0.x.x, however downgrade from v2.0.x.x to v1.1.50.39 is restricted by design, there is another downgrade transition image to support downgrade from Insight-enable to non-insight support image, but it's for internal usage and not posting officially.
Thanks Dana for your reply.Really appreciated.
You're right, I have a typo in the firmware version number. it is 2.0.1.2
There is no settings that could generate such traffic or port flapping... The reason is simple: since that firmware upgrade the switch has been resetted to factory default and relocated to an administrative subnet. Yet, it continue to generate SSDP traffic on one interface. After 48-72h, all lights on the front starts to flash, indicating it is time for a reboot...
I'll generate the tech file and contact support.Thanks for the tip.
