Lamp is bricked after Yeelight software upgrade

I got my LED Mi 1S lamp, today I opened the Xiaomi Home app, and the app asked me to perform the software upgrade of my lamp - because the current software version is 2.0.6_0007 and the newer one is 2.1.7_0020.

After the upgrade my lamp doesn’t work anymore!

Yeelight please help me or maybe us. You can send me the original firmware so I can flash it - if you prefer that option or provide any other help to your customers.

You guys make very good products, why your customer support is not helping us with this “firmware upgrade” problem?
