I bought some Athom 7W RGB bulbs two (or three?) years ago shortly before the firmware image was changed from 2M to 1M. I've read online that the 2M flash on the bulb means that upgrading using standard Tasmota firmware will brick the bulb.
Where can I find a new version of Tasmota to upgrade the bulb? And, once it's upgraded with this new firmware will I be able to upgrade using standard OTA Tasmota images?
