Atrim Z-Wave Stick Upgrade

Has anyone managed to update their Atrim Z-Wave controller? Their support doesn’t see to respond. It fails when I try via zwave-js-ui. The stick currently has 7.17. I tried updating via SimplyStudio and that fails too.

Based on the KB I tried to install the latest zwave_ncp_serial_api_controller_BRD4204D.gbl from the gecko repo on github.
