Firmware downgrade request(my ceiling lamp automatically turns off after firmware upgrade)

Hi, Dear Staffs.
My Yeelight Ceiling Light(650) turns off automatically everytime when I turn on. It started right after I updated firmware for the light.

I already did factory reset several times but it didn’t work.

I DEEPLY NEED the downgraded firmware.
Please whitelist my yeelight mi account so I can downgrade or change the firmware.

My Mi ID is 1599377845 and the model is yeelink.light.ceiling4

I appreciate your help and look forward to hearing from you soon.


Any luck. Was it fixed?
