Downgrade firmware request


Just updated my YeeLight bulb. But now it goes insane. I use a application called Lumia Stream to control these bulbs. It really helps me getting the best out of my bulbs.

For some reason, when I updated the YeeLight Bulb 1S it just went insane. When controlling via Lumia the bulb turns on and off and eventually it crashes into a full reset which forces me to reconnect it to the YeeLight app.

I need a downgrade option. Because it is really important for me that this light works.

Can someone help me? It’s pretty urgent.
