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","oldversion":"20230511-223416/v1.13.1-gb0b8c19"}

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

The LOG: _122687570:1687699693973873 mgos_sys_config.c:323 Saved to conf9.json 122967750 mgos_http_server.c:180 0x3fff2a04 HTTP connection from 192.168.178.98:50679 125867680 mgos_http_server.c:180 0x3fff2a04 HTTP connection from 192.168.178.98:50680 125887472 json.c:426 RAM: 50936 total, 35220 free 130219455 mgos_http_server.c:180 0x3fff2b34 HTTP connection from 192.168.178.98:50681 130227358 shelly_update.c:168 Starting ota from http://ota.tasmota.com/tasmota/shelly/mg2tasmota-ShellyRGBW2.zip 130253967 mgos_http_server.c:180 0x3fff2b34 HTTP connection from 192.168.178.98:50682 130733276 mgos_ota_http_clien:276 Update URL: http://ota.tasmota.com/tasmota/shelly/mg2tasmota-ShellyRGBW2.zip 130895693 mgos_ota_core.c:268 Starting, timeout 240, commit timeout 0, mem 34416 130936458 mgos_ota_core.c:652 FW: rgbw2 esp8266 0.3.1 20201204-114410 sig 0x00 130940819 shelly_update.c:90 BEGIN: rgbw2 130944970 shelly_update.c:98 will not update rgbw2-white with rgbw2 130949113 cloud_aes.c:165 Cloud already closed or not connected 130954564 mgos_ota_core.c:1050 Update finished, result -13 (Aborted by event handler) 130965639 shelly_update.c:111 SHOTA: error Aborted by event handler 130969646 shelly_update.c:130 OTA is fubar 130974832 mgos_system.c:58 Rebooting in 500 ms 131429191 esp_main.c:138 SDK: state: 5 -> 0 (0) 131434069 esp_main.c:138 SDK: rm 0 131438529 esp_main.c:138 SDK: pm close 7 131446738 mgos_wifi.c:70 WiFi STA: Disconnected, reason: 8 131452463 esp_main.c:138 SDK: sleep enable,type: 2 131458280 mgos_net.c:84 WiFi STA: disconnected 131463387 shelly.c:312 WiFi status=1313166336; mode=1 131469132 coiot.c:491 Coap listener 0x3fff2274 is closed! 131474397 coiot.c:616 coapconnect, WIFI status=1313166336 mode=1

+1 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):

150045268 mgos_ota_core.c:1050    Update finished, result -13 (Aborted by event handler)

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
