Next Steps After Teardown for TUYA Cloud Cutter Pull Request on LEDVANCE Bulb

gramais 

Hello everybody,

This is my first teardown of a bulb that I would be happy to "cloudcut" ... :)
(Below you'll find the pictures I took from the teardown)

Manufacturer: LEDVANCE
Model: Filament Globe 125 53
Socket: E27
Luminous flux: 680 lm
Power: 6W
Board: Beken 7231T
WiFi-Module: WBLC5

I am not sure: what would be the next steps to get a pull request to the TUYA cloud cutter?

Any help would be really appreciated -
thank you!

Well, first you need a 2MB flash dump and then you can submit it for them to add profile. I can submit it myself, can you share 2MB backup here? We can also use it to extract OBK config. [Read more]

I think you may have got it right at the first try. Regarding the UART port - well, you should check our YT channel for detailed flashing process presentations: https://www.youtube.com/@elektrodacom You... [Read more]

Okay, so I started the first attempt - unfortunately without success :( I double-checked everything and swapped RX/TX to be on the safe side, but maybe you could take another look: the photos are below. I... [Read more]

Hi, how did you remove the bottom screw without breaking the glass? Is the stock tuya firmware patched? [Read more]

How do you power it, how long are the wires, what kind of USB to UART converter? Have you tried swapping RX and TX? [Read more]

Hey @ferbulous, I heated the socket with a heat gun until I could simply twist it off... I had imagined it would be more difficult, but then it went very easily. :) And as for the firmware patch: no... [Read more]

Those wires seem very long. Futhermore, your USB to UART converter does not look like the one that can provide enough current for flashing. Use a better 3.3V source and shorten your wires. Have you watched... [Read more]
