Flashing Mirabella Genio RGB+CW/WW I002741 Downlight

  • See below for how I flashed a Mirabella Genio RGB+CW/WW I002741 Downlight I purchased from KMart.

    I have done a full dump, and it can now be flashed using tuya-cloudcutter.

    If you do need to open it (although with cloudcutter this should not be required), this one is fairly easy, and there's no glue!

    - Make sure it is disconnected/unplugged from any power outlets!
    - Undo the only screw on the back and lift the cover
    - Undo the screws holding in the cable, and remove it
    - Undo the screw below where the cable was
    - Starting on the cable side, carefully pry the cover open, there is a click either side of where the cable comes in, and then one opposite
    - You can now access the controller board, if you undo the 2 screws in the controller board, it just pulls up and off

    Flashing involves connecting to the pads on the back of the CB2L board (specifically RX1 and TX1). I found it was easiest to connect to the pins of the capacitor across the GND and 3.3V rails.

    The config:
    {
      "vendor": "Tuya",
      "bDetailed": "0",
      "name": "Mirabella Genio RGB+CW/WW Downlight ",
      "model": "I002741",
      "chip": "BK7231N",
      "board": "TODO",
      "keywords": ["downlight"],
      "pins": {
        "7": "BP5758D_DAT;0",
        "8": "BP5758D_CLK;0"
      },
      "image": "https://obrazki.elektroda.pl/YOUR_IMAGE.jpg",
      "wiki": "https://www.elektroda.com/rtvforum/topic_YOUR_TOPIC.html"
    }


    I found I needed to reboot the device after setting the config, and then run the following command (Launch Web App > Logs > command section at bottom) - not sure why this was not the default, or maybe I had some how changed it, but this worked:

    Hmm the default BP5758 mapping is the mapping that worked for my device, and it has a slightly different order.

    By the way, since the latest Web Application Update, you can also set LED remap from Web Application -> Tools section. That way you don't have to use console commands.

    Hi There,

    I've been trying to flash these downlights (BK7231N Version) using cloudcutter but with the firmware that came on them (V1.5.21) I can't seem to use this exploit.

    Is it simple to get a new profile created for this firmware or am I up for alot of soldering...

    Cheers,

    AJ

    I am not sure but Tuya patches their firmware a lot these days. And soldering is not that hard. We have some guides showing the procedure step by step.
    You can, for example, follow this tutorial:

    Thanks Both,

    Appreciate the quick response!

    Looking at your breakdown video, it is indeed a different casing...

    it looks like i'll have to take the local tuya route then (unless you have any better suggestions, as i have 40 of these!

    Are all v1.5.21 out of the box? Or maybe you have updated your one?

    Hi Thanks for your research, I have the same unit (Dead from Bunnings bargain table) with a different part number. I wish Id found your post earlier.

    Cheers Rod
