Seeking Help Connecting Kauf Bulb to USB/TTL Adapter

I have several kauf rgbww bulbs which appear to be bricked - eitheraskign for a password I don’t have or not providing an ap.

If I understand things correctly I could theoretically connect the bulb through a USB/TTL adapter and falsh it directly. Is that correct?

And if so, I understand that I’ll need to connect pins on the bulb to the adapter, and therein lies the rub. I’m not sure which pin on the bulb is which.

Attached is a photo of the bulb. Can any identify the pins for me?

Thx in advance.

It’s possible you may need to tear it down further to access the boards pins.

This may give you some hints on that.
