My Tasmota devices are all using TLS so I install new firmware in each. I have worked on 6 of the Tasmota 15W Color Bulbs and five of the six went great, but it seems like I bricked one. I assume I need to pop the 'bulb' off and go the hardwire method. Is there a write up or picture showing the connections?
Lastly, the update process I do is to replace the firmware with the minimal tasmota firmware (to make room for the TLS version), then upload the TLS firmware. The only thing I did differently is that right before I updated to the TLS version I toggled the light off (it was bright and I was tired), the update seemed to work but it did not come back from the reset. Just an FYI
