LED Ceiling Light Died After firmware upgrade

2July2017 was upgrading my firmware for 2 of my Led Ceiling light, 1 survived, the other died.
Died as unable to turn even with power switch. Confirm by swapping the 2 ceiling light.
Any ways of resetting the ceiling light? I am using Mi Home on Andriod, the light is only <3mths old.

This is a serious firmware bug that caused by a corner issue. Do you have a Paypal account and a receipt? We will contact you for a refund. Really sorry for this situation.

Now I’m too scared to update the firmware on mine. Has this been fixed? @weiwei

Not yet, we will offline 1.4.8_166 today.
Please wait for firmware 1.4.8_167.
