one of my particle devices isn’t connecting to the network anymore. After switching it on, it just starts blinking green fast (about twice a second) and is getting hot. When trying to get it to setup mode (pressing “setup” for more than three seconds) it once blinks blue and then continues blinking green. You can get it to dfu mode, but after flashing the tinker firmware it will not work anyways. Since this device worked before in my light installation i think it is gone to meet its maker? Or is there any chance to get it working again?
