Hi, Is there a way to downgrade to a previous version of the firmware?

I updated the firmware yesterday and now I am having some problems. I have 2 x E4 Decos, working in Access Point mode. The second Deco is intermittently losing connection to main deco and I am frequently getting the "We couldn't find Deco" error in the Android App on my phone.

My biggest problem after the update is, it seems that I cannot access my IP cameras from within my local network. Before the upgrade I could access my IP cameras with the IP Cam Viewer app on my phone (when connected to my local network), by using their local IP addresses (10.0 0.xx). Now I can only access them by using DDNS.

Both IP cameras also displayed video in "Home Assistant" before the update, but now they don't. Home Assistant uses local IP addresses to access them.

Is anybody else having similar problems after the update? I cannot think of any other changes on my network that could be the cause of the problem. If I can change the firmware back to a previous version, I will be able to tell if the update caused the problem.

Thanks. 

Just an update, I saw about the new "Isolated from main network" option in another thread. My IP cameras are on the Guest network, so I switch off the option for guest network to be "Isolated from main network" and now my IP cameras are visible again. So problem seems to be solved now, thanks.

@TP-Link_Deco Any ideas on how to fix my deco e4? After the update, 1 of my deco unit got stuck, bricked in yellow light. Not pulsing blue. Even after resetting it.
