Serial Flashing

One of the more difficult bulbs as interconnect has to be desoldered

Diffusor can be pulled of after breaking the glue by turning it (no knife necessary), glue residue must be removed from in between housing and heatsink. Two screws to remove and the interconnect between LED-PCB and Controller has to be desoldered. Afterwards, LED PCB can be pulled of. Heatsink can be removed by prying open using a small screwdriver in gap at the edge. Lots of white glue all over controll board, can be cut with sharp knive to pull out the PCB a tiny bit and get access to ESP (TYWE3L) To get more space, bottom of the bulb can be screwed lose - was easy on 1/4 bulbs, possible with decent force on 2/4 and impossible on 1/4 bulbs I tried. But even without there is just enough space to be able to solder. For reassamby, do the steps in reverse and resolder the inter PCB connector.
