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:
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... [Read more]
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... [Read more]
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: [Read more]
That version (v1.5.21) has been patched unfortunately :( https://github.com/tuya-cloudcutter/tuya-cloudcutter/wiki/Known-Patched-Firmware It's the same for all the ones from Bunnings as well (but they... [Read more]
Thanks Both, Appreciate the quick response! Looking at your breakdown video, it is indeed a different casing... https://obrazki.elektroda.pl/9927211000_1703024976_thumb.jpg it looks like... [Read more]
Are all v1.5.21 out of the box? Or maybe you have updated your one? [Read more]
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 https://obrazki.elektroda.pl/6515... [Read more]
