Impossible to reset my Yeelight Led bulb color


To explain my situation, after playing during 30min with my light and after updated it, I have tried to turn off the bulb from the application on my iPhone and since that it’s impossible to turn the light on.

The light is connected to the WiFi hotspot of my android phone as my iPhone.
As I didn’t achieve to turn the light on through the application, I decided to reset the light.

However, after a dozen of try to power on/off the light, nothing happens. I can hear the sound of the light when I turn the power on but no light, no blink, nothing…

Does anyone have an idea?
