Unable to flash new firmware

klein0r commented 5 years ago

Just received my new Sonoff R3. After that:

I've included it in my eweLink app
Updated the firmware to 3.1.0
Created a new hotspot named sonoffDiy
The Sonoff joined the network successfully
The GUI tool found the Sonoff and I am able to power it on and off

That's it. But that seems to be the dead end. Issues:

I am not able to flash a new firmware by using the GUI. After clicking "OK" nothing happens. I'm just able to close the program.
I am not able to change SSID and Password by using the GUI. "Command send". Thats all. The device is still joining sonoffDiy all the time
I am not able to flash new firmware by using the API. Can you provide an example curl request? This one fails (unable to connect):

curl -d '{"sequence": "1561217426","deviceid": "1000900d70","encrypt": false,"data": {"downloadUrl": "http://files.haus-automatisierung.com/sonoff-minimal.bin","sha256sum": "c22c9d136e3d449e317e9cee4f538bb0fb1b1c9b5c187ecb0a78378d2d410c6e"}}' -H "Content-Type: application/json" -X POST http://192.168.179.21:8081/zeroconf/ota_flash

What is the correct port? Port 80 and 8081 is not responding.

klein0r commented 5 years ago

dns-sd -B _ewelink._tcp (on MacOS)

returns

Timestamp     A/R    Flags  if Domain               Service Type         Instance Name

Since I know the instance

dns-sd -L "eWeLink_1000900d70" _ewelink._tcp. (on MacOS)

returns

18:14:12.328  eWeLink_1000900d70._ewelink._tcp.local. can be reached at eWeLink_1000900d70.local.:8081 (interface 5)

But this tells me port 8081 (which is not responding by using curl to communicate with the HTTP api)

Did you check the original code as reference ? https://github.com/itead/Sonoff_Devices_DIY_Tools/blob/master/code/lan_ewlink_api.py#L456 ??

klein0r commented 5 years ago

Yes of course. But nothing is responding. Even switching on and off results in a timeout...

ZZLinvec commented 5 years ago

Do not power down the equipment! Swiping third-party firmware requires networking (used to unlock devices) Does your hotspot have Internet access? You can open the tool and try again.

klein0r commented 5 years ago

@ZZLinvec I've tested every possible combination. Both devices have Internet Access, mDNS and ping is working.

Everything seems to be correct, but the HTTP-API is not responding. The DIY mode is way to complicated right now. I'm a software developer and I was not able to flash a new firmware with your tools within 5 hours. How should a "normal" user achieve that? I will use the normal header pins now. That process is finished within minutes.

ZZLinvec commented 5 years ago

You still can't control it with tools?

klein0r commented 5 years ago

I can switch it on and off with the tools. But I'm not able to flash new firmware...

ZZLinvec commented 5 years ago

During the upgrade, the device needs to connect to the server. Whether the current hotspot is connected to the network?

klein0r commented 5 years ago

During the upgrade, the device needs to connect to the server.

Seriously? Why?! But yes, there was a working internet connection available.

Conclusion: The DIY mode is totally over engineered. Don't try to use it - to many pitfalls. Just use the normal pin headers to flash it within seconds...

Yeah, Sonoff - please make DIY useful!

rradar commented 5 years ago

I should have read this early. This sonoff "diy" mode is just a pain in the arse... @ZZLinvec

I'm going to switch to shelly.... price difference is small but time is priceless.

ZZLinvec commented 5 years ago

Please tell me what kind of device or function you want

ZZLinvec commented 5 years ago

@rradar

klein0r commented 5 years ago

@ZZLinvec Easy. The DIY-Jumper is a great idea. After setting that jumper, just start the sonoff in access point mode and offer a html website to set

wifi credentials
mqtt credentials (for using your own broker)
optional file upload to replace the firmware with e.g. tasmota and checkbox that warranty is lost after replacing the firmware

No additional tools, no cloud account necessary, easy to use and it will work on any operating system

{"downloadUrl": "http://files.haus-automatisierung.com/sonoff-minimal.bin","sha256sum":

I had the hardest time flashing this device as well. I had to read the source code before I got that eureka moment.

YOU MUST RE-HOST the flash binary on an HTTP server on your local network to flash the device. It WILL NOT flash from an internet source!!!!!! And the device will not give you any indication that was the issue!

https://github.com/itead/Sonoff_Devices_DIY_Tools/blob/master/code/lan_ewlink_api.py#L101 def set_ota_flash(self,info):Set the firmware download address on the device LAN**

My Steps

To unlock the device and per the source code "equipment is no longer under warranty"

$ curl -X POST -d '{"deviceid":"","data":{}}' http://192.168.1.22:8081/zeroconf/ota_unlock

Verify look for otaUnlock = true

$ curl http://192.168.1.22:8081/zeroconf/info -XPOST --data '{"deviceid":"","data":{}}'
{"seq":24,"error":0,"data":"{\"switch\":\"off\",\"startup\":\"stay\",\"pulse\":\"off\",\"pulseWidth\":500,\"ssid\":\"XXX\",\"otaUnlock\":true}"}

Please note: JSON "data" element is a string not an object per the 1.4 spec. So, any parsing needs to support both data: "{}" and data: {} formats. For an example see the Perl lib https://metacpan.org/pod/Power::Outlet::SonoffDiy

$ curl http://192.168.1.22:8081/zeroconf/ota_flash -XPOST --data '{"deviceid":"","data":{"downloadUrl":"http://192.168.1.4/tasmota/tasmota-lite.bin","sha256sum":"adda99154658eb1d5c263abfd10c572f45e1cc813e37e3390e879e1b670cb9f0"}}'
{"seq":2,"error":0}

Other sites say do NOT use sonoff-minimal.bin. So, I would not use that either.

jofrep commented 4 years ago

thanks @mrdvt92 I was going through the same process and you saved me a lot of time.

dennybaa commented 4 years ago

I agree with the all above it works really bad...! Just imagine this doesn't work, the json parser :)

curl http://$device_url/zeroconf/ota_flash -X POST \
    -d '{"deviceid": "$device_id", 
          "data": {"downloadUrl": "http://$server_ip:38181/tasmota.bin" , \
                  "sha256sum": "$shasum" } \
        }'

Though

curl http://$device_url/zeroconf/ota_flash -XPOST \
    -d '{"deviceid":"$device_id","data":{"downloadUrl":"http://$server_ip:38181/tasmota.bin","sha256sum":"$shasum"}}'

worked at least I got {"seq":5,"error":0}, I removed all the spaces, lol... Maybe at least ITEAD should care about the docs more.

klein0r commented 4 years ago

@dennybaa Seriously? That would explain why I was unable to flash a new firmware with my curl request...

Are you developing a bash script for the flashing process?

mrdvt92 commented 4 years ago

Are you developing a bash script for the flashing process?

I was thinking about building a Perl script (Perl runs on everything) that would do something like this:

script.pl [-u url] $sonoffDiy_id_address

download from url default http://thehackbox.org/tasmota/release/tasmota-lite.bin
start a web server
send ota true setting
send ota upgrade

I think the hardest part would be ensuring the Perl web server supports the "range" requirement. If that's really needed. I only have one mini left with SonofDiy firmware, And, since it's a one-way street, there is no way to go back to re-test.

I also have updated the documentation on my fork on Github

dennybaa commented 4 years ago

@klein0r Hey. Yes here it's https://gist.github.com/dennybaa/bfa002e5b3acd38b8f68e4555aaf8eac. In fact there was a problem with the payload. Anyways the flash API method does not validate the JSON and the process hangs forever( I was able to flash 1 of 5 sonoff minis successfully, 4 of them were bricked after the DIY flash, so I had to solder lol and use tasmotizer to flash :)) So DIY mode is really buggy. Be prepared for a brick. PS. all of the devices had stock 6.3.0.

pgScorpio commented 4 years ago

I found a solution that seems to work

Place your binary file(s) on a public accessible network folder on the network and select the binary from that network share !

gdespirito commented 3 years ago

I finally did it. I am on a M1 Mac, so i can not use DIY Tools (some videos i saw did it using that tool).

What i had to do, is to create a local server on my machine that Accepts the range header. That was the tricky part. Find a tool that accepts that header out of the box.

I just made a Node.js express server to serve the static tasmota-lite.bin file. That should do the trick.

I created a server folder and inside:

mkdir server
cd server
npm install express
touch index.js

Then i created a index.js file with this:

const express = require('express');
const app = express();
const PORT = 3000;

app.get('/', (req, res) => {
    res.send('Hello World!');
});
app.use(express.static('public'));

app.listen(PORT, () => console.log(`Server listening on port: ${PORT}`));

Then I started the server:

node index.js

Finally, i created a public folder inside my server folder with the tasmota-lite.bin file. Then i just used POSTMAN to request the sonofff to update the firmware:

Note: That 172.20.10.6 was mi local network IP. I was connected to my iPhone on a network called sonoffDiy and password 20170618sn on both my computer and the sonoff mini R2. I did not tried to make this process conneted in my wifi network, but i think it should work as well.

gdespirito commented 3 years ago

I`ve just created a Node.js Tasmota installer :)

Check it out: https://github.com/freshworkstudio/node-tasmota-installer

Just run on your machine and follow the wizard:

npx tasmota-installer

hi, i had problem in turn basic R3 into a DIY mode. I did all steps to get into DIY mode but it didn't respond. I deleted the device in eWeLink App. I did all steps again and tachannnnnnn , it works Maybe was that all your problem like klein0r

unbelievably, this worked. it seems that deleting the ewelink app resets the device to factory settings. I was able to flash finally using the tool from @gonzunigad on my Mac. Thank you for that tool! it rocks
