Hello,

I am trying to flash Teckin SP-20 Smart-WiFi Plug. It uses ESP8266.

I tried to flash device with my firmware file, but the error message says that file does not exist.
After that, I tried to flash sonoff-basic.bin file, but it says that the file does not exit, but it is there.

Next steps:
1. To go back to the orginal software
   # curl http://10.42.42.42/undo

2. Be sure the conversion software runs in user2
   # curl http://10.42.42.42/flash2

3. Flash a third party firmware to the device
BE SURE THE FIRMWARE FITS THE DEVICE AND USES THE CORRECT FLASH MODE!
MAXIMUM SIZE IS 512KB
put or link it to ./files/thirdparty.bin
A basic build of Sonoff-Tasmota v6.5.0 is already included in this repository.
   # curl http://10.42.42.42/flash3
Alternatively let the device download and flash a file via HTTP:
   # curl http://10.42.42.42/flashURL?url=http://10.42.42.1/files/thirdparty.bin

HAVE FUN!

Can you help?
Thank you.

Thanks for reporting, I forgot to update that message when I combined flash3 and flashURL. I'll fix it shortly.

If you just want to flash sonoff-basic.bin, do curl http://10.42.42.42/flash3. If you want it to download a given URL, use curl http://10.42.42.42/flash3?url=....

Thank you for your reply.

I want to upload the specific firmware, not sonoff. I used sonoff just to test that neither custom nor sonoff firmware works.

Should I use

curl http://10.42.42.42/flash3?url=http://10.42.42.1/files/custom.bin

when I want to use custom firmware?

[kueblc]

Yes

Hello, world

Please make sure to note the correct SPI flash mode!
Installing an alternative firmware with the wrong flash mode will leave the ESP unable to boot!

Next steps:

1. To go back to the orginal software

   curl http://10.42.42.42/undo

2. Be sure the conversion software runs in user2

   curl http://10.42.42.42/flash2

   curl http://10.42.42.42/flash3

Alternatively let the device download and flash a file via HTTP:

curl http://10.42.42.42/flash3?url=http://10.42.42.1/files/thirdparty.bin

Seems like a simple path error but I've tried all I can think of. Any ideas please?

Further:
the device is a smart plug from Shenzhen Core Image Co but I've tried a Blitzwolf SHP3 with the same results. I'm getting a Hello World from the device, not the flash detail I expected.

Please open a new issue for this is unrelated to the issue you are commenting on. Are you running tuya-convert on a device with IP address 10.42.42.42? This would break the script as the script checks for your IoT device at that address.
