My yeelight led bulb (white) couldn't reset


Hello dear friends,
I have a yeelight bulb that refuses to be reset. I tried to reset it like hundred times but it did not blink. (After turning it on/off 5 times) So i can not connect my device to app.
Do you have any suggestions to fix it?


Was the device used to work?


Ah yes, when i update the app it disconnect.
