Recently installed an RGBW2 - initially it came up in AP mode fine, I connected, configured wifi and it re-connected in client mode fine. I was able to get to the web interface and change colours, white level etc.
Some time into using the device I tried to use one of the "Chase Mode" buttons. The lights didn't chase and instead the device webpage suddenly became unresponsive. I removed power and connected again, however the device would not respond or connect to WiFi.
I followed the instructions for resetting the device using the small button on it, but this did not work. As soon as I press the reset button the LED tape goes green and stays solid, the instructions say it should flash.
I have tried to reset multiple times following the instructions and it will not go into AP mode.
I have some experience flashing Sonoff devices and have a USB adaptor to do it, so if support can provide instructions and firmware I might be able to do it, but I also would like to know why it's broken.
