LED Ceiling Light Stopped working After firmware upgrade


I have just updated all of my 3 Celling light to the latest version, now none of them works even not by turning on the switch manually, all of the 3 celling light are completely useless now, is there a way to reset them?
just received the latest one 2 days ago…

When the ceiling lights do firmware upgrade, it will be turned off for some time, it’s normal process. If you power off the lights during that window, the upgrading process is interrupted, you need to turn on the lamp again and wait for a while.
