After firmware update bulb doesn't turn on or reset

I have a problem with Yeelight Color Bulb.
After firmware update, it is not turned on or reset. Turning on and off 5 times does not help, the bulb only blinks at the moment of shutdown.
The mains voltage is correct, 220V
PS: sorry for google translate :slight_smile:

If you can’t turn it on, it’s a hardware issue, you can contact your seller to replace one for you.
