GS6 Gigaset /e/OS Web-Installer

Hi.

I have a new GS6 and am trying to flash e/os using the web installer.

However, when I select the device and click “Connect,” I get the following message:

Device model not supported

Your phone E940-3043-00 is not compatible

You cannot install /e/OS with this tool.

What could be causing this?

It currently has A15 (stock) installed.
