Flashing Beken Software on LSC RGB Bulb 970719.1 for Pin Settings

Help with LSC RGB Bulb 970719.1
I managed to get this device out of tuya cloud by using cloud cutter. Then i took the usual procedure to take the device to home assistant into esphome.
Unfortunately i forogt to figure out the pin settings with the ichiptool and so i am stranded in esphome now. The light bulb is always on an i cant turn it of. I cant change the brighness or colors.
Is there a way to flash beken software on it, to figure out the pin settings?
I got it out form tuya cloud by using: lsc-2578539-970724-white-and-color-ambiance-e27-806lumen.json wich is not the exact firmware but with: lsc-2578539-970719-rgbct-bulb-2.9.27.json or lsc-2578539-970719-rgbct-bulb-2.9.6.json the cloud cutter exploit did not work.
So i hope someone could help me out and thanks in advance.
Yours
Peter

AI: Have you tried any other troubleshooting steps besides using Cloud Cutter and attempting to flash Beken software? If so, what were they?
Not yet. I tried to flash beken via ota form esphome but it did not work (magic size missing or so)

If your software does not support the automatic, online config extraction, then you can try migrating to OBK and using WebApp to extract Tuya config partition:
https://github.com/BenJamesAndo/OpenBeken_uf2_firmware

Alternatively, you can try searching known devices templates until you'll find a match.

Have you tried to open the bulb to confirm that's using bp5758d chip?

Thank you very, very much for your fast help. With your help I could get openbeken on the device right now. And from there I can toggle the light. With your web tool I flashed the first template on the "import"-page called "RGBCW LED" and it works. The only problem I have got now, is that the colors don't match and the warm/cold output. Is there a way of getting these values or can I just try it out? At the moment the config says: P7(PWM1) PWM 1 / P8 (PWM2) PWM 5 / P9 (PWM3) PWM 2 / P24 (PWM4) PWM 3 and P26 (PWM5) PWM 4. I did not open the device because I wanted to avoid damaging something inside... Thank you very much for your answer! Yours Peter

It's good to hear you've got a progress. I can also try to help with the colors, but first you need to specify what is exactly wrong? There can be multiple things that needs adjustment.

1. Do you mean that Warm is swapped with Cool, etc? If so, you need to reorder channels in configure module, and by that, I mean just swap 4 with 5 channel indexes (or if you use indexing starting with 0, then swap 3 and 4).
The same goes if Green is swapped with blue, blue with red, etc, etc, in any case, you just need to reorder indexes in Configure module.

The expected channel indexing is like RGBCW, so R = 1, G = 2, etc,

So, just try to determine which PWM is which color, and then swap indexes, save, retry, check if order is good, if not, reorder again....


2. Or do you mean that you have this strange kind of bulb with "alternate PWM control", where on slider controls CW brightness, and second temperature? If that's the case, we have a flag for that, called "[LED] Alternate CW light mode (first PWM for warm/cold slider, second for brightness)"

3. Alternatively, if basic colors are matching (red is kinda red, green is greenish, blue is blueish, etc), and you want to tune colors better, you can use color calibration;

EDIT:
Or try those steps I mentioned alreAdy , try to get Tuya config:
https://youtu.be/WunlqIMAdgw

Thank's a lot; I followed the video again step by step and now it worked: The original tuya config from the device is:
Device configuration, as extracted from Tuya:
- LED Green (Channel 2) on P9
- LED Cool (Channel 4) on P26
- LED Blue (Channel 3) on P24
- LED Warm (Channel 5) on P7
- PWM Frequency 1000
- LED Red (Channel 1) on P8
Device seems to be using WBLC9 module, which is using BK7231T.
And the Tuya section starts at UNCOMMON POSITION 0

So finally it works perfectly - thank you very much for your great help!

Nice, can you also share the JSON template from the Web App, so we can add this device to our devices list here:
