As others had noted in months prior, upgrading the Athom bulbs via the Tasmota OTA protocol breaks them. Dead. Is it still true that there is NO FIX for this that doesn't involve disassembly of the bulb, soldering skills, and technical know-how?
We need some help from Athom on this. Guidance on disassembly? How can we use the header on the top of the LED board to reset the bulb? At least, confirm the pin-out.
How about adding a hard reset button that avoids the need for disassembly?
