Hardware Bakibo 9W E27 RGB CCT bulb - xoseperez/espurna GitHub Wiki

This bulb is internally equivalent to Teckin SB53. ASIN: B07SPVCG59, found on Amazon and other stores.

To flash, pop open the plastic bulb cap in an unscrew motion to reveal a LED panel with a protruding ESP 8285 board with 1MB flash.

Remove the three screws attaching the LED panel to the bulb. This round LED panel is connected to the rest of the circuit by means of a central pin header connector. You can then remove it completely to reveal the ESP

Bend the ESP board slightly to make some space to solder wire to the GND, VCC, TX, RX and GPIO0 pads underneath. You do not need to completely desolder the ESP as in the below picture:
