Faced a problem after updating the lamp to version 2.1.7_0028. Yeelight YLXD50YL (yeelink.light.ceiling20) DIED after update. My topic on the Yeelight forum: CLICK

If I find a working firmware, I can download the firmware from it and restore a non-working lamp, right? #21

If the device isn't physically damaged you can flash this firmware to the ESP. If you own a firmware dump of a second device you could flash the dump to the ESP. Both is possible.
