Shelly RGBW2 refuses to flash

[thunder312]

Hi folks,
I just tried to flash my Shelly RGBW2 with Tasmota.
The links was (using tasmota, because dasker is offline):
http://192.168.178.75/ota?url=http://ota.tasmota.com/tasmota/shelly/mg2tasmota-ShellyRGBW2.zip
Is it possible, that the pre-built patch isn't suitable?
Because as far as I read the log (below), the Shelly accepts only patches with "rgbw2- color" or "rgbw2-white".
Yes the shelly can handle 1 color led stripe or 4 white led stripes.
I tried both modes, before patching.
Do I need to build my own patch? Please say no. :-/

The JSON output was:
{"status":"updating","has_update":false,"new_version":"20230511-223416/v1.13.1-gb0b8c19","old_version":"20230511-223416/v1.13.1-gb0b8c19"}

As you can see:
old version = new version, which is the newest Shelly default firmware.

The LOG:

Same issue, either get
will not update rgbw2-white with rgbw2
or
will not update rgbw2-color with rgbw2

[chrishick]

Same issue, same FW version 20230511-223325/v1.13.1-gb0b8c19

Hello,
I repacked the archive and it should work now, if you are on the rgbw2-color mode. Link you can use is here:
http://dl.nekohell.eu/mg2tasmota-ShellyRGBW2c.zip

How did you repack? Can you also repack for the Dimmer2? Many thanks in advance.

[pedymaster]

Depending on what is the problem with dimmer2

In this case, I had to unzip the version that was failing with will not update rgbw2-color with rgbw2. There is a manifest.json file, where I had to replace rgbw2 with rgbw2-color to fool the original shelly.
This needs to be carefully repacked again. Carefully, because the files then have to be repacked and the manifest.json has to be the first file in new zip. On linux it goes like zip -Z store -r mg2tasmota-ShellyRGBW2c.zip ./rgbw2-0.3.1/manifest.json ./rgbw2-0.3.1/esp_init_data_default_v08.bin ./rgbw2-0.3.1/fs.bin ./rgbw2-0.3.1/rboot.bin ./rgbw2-0.3.1/rgbw2.bin

So if only the renaming is needed, here is your manual :-) I have found this on some german forum. Not much else I can do in case it does not work.

[thunder312]

@pedymaster Good solution and very easy. 🥇

[bbccdd]

That worked great indeed pedymaster.

In my case it had to be rgbw2-white instead of color that did the trick.

[it-guru]

I have the same problem as bbccdd - i also need a image for rgbw2-white . I already have take a look at mos tools, to build a image by my own - but i wasn't able to get mos running on my debian.
Please help!

[pedymaster]

And what exactly are you missing in this thread?
Either before flashing configure your shelly rgbw2 to color mode instead of white (and then you can use my image) or just replace rgbw2-color for rgbw2-white in my steps and make your own

[it-guru]

Oh, ok.
Thanks for the info - but i have already flash it with a FTDI Adapter. I will try it on the next device (i have some in the ToDo list :-).

[ChrisVonFrosta]

@pedymaster there are 2places with rgbw2. which one need to change in rgbw2-color?
"name": "rgbw2",
"src": "rgbw2.bin"

[pedymaster]

Hey, I believe its just the name, you can double check it in the image I provided - http://dl.nekohell.eu/mg2tasmota-ShellyRGBW2c.zip (or you can just use that one)

THANK YOU SO MUCH!
That's perfect

[Kinggrass]

Hi together,
I also want to flash my rgbw2 but nothing is happening ,,, :/
Tried both urls:
http://ota.tasmota.com/tasmota/shelly/mg2tasmota-ShellyRGBW2.zip
and
http://dl.nekohell.eu/mg2tasmota-ShellyRGBW2c.zip
without success :/

My RGBW2 is in color mode.

Its my first shelly, how can I get the log?
Under Logs over the shelly web ui nothing appears.

Edit:
Okay, found out to retreive the logs (by right click & download and not simply opening the link):

Like expected as I read this thread, the tasmota link is not working because of the color suffix refusal. But looks like it can connect to it.

But I dont get why the nekohell link is not working. I can download the zip normally over the browser.

Someone any guess?

Edit2:
Don't exactly know the issue (maybe because its redirected to https instead of http), but hosted the file locally on my Synology NAS, and this worked,
thanks to @pedymaster
