Cannot flash Topgreener TGWF115APM

[ipher]

Topgreener TGWF115APM, device is printed with "1810Ver1.0.1" on it. Using a Raspberry Pi 3B V1.2 to flash

There seems to be a fault in smarthack-psk.log

edit: cracked it open and here's the markings on the chip.

I am experiencing the exact same issue attempting to flash TopGreener Smart Plug: TGWF115APM. I also have the same version 1810 Ver 1.0.1 printed on the device. I am using a Rasberry Pi 4 running the tuya converter using docker. But seeing the same issue with smartconfig procedure looping with no success.

Same here though I have a 1906Ver1.0.1 but the wifi chip has the same markings.
That device was running using the official app for few months so maybe it got a firmware update that prevent re-flashing...

I tried an unused one that I bought a year or so ago, that had never been connected to the app, and it didn't work either. Since it was never connected to wifi or the app I don't think it was a recent update that prevents this

Hi,
I´m not sure this is the same issue I had - but in my case I really tried everything I could think of with no success.

In the end this modified procedure allowed me to flash my devices:

I'm able to connect to the vtrust-flash SSID from the 2nd computer (Android tablet) and I can see that my TopGreener device also connects to it.
If I follow the procedure and put the device in Pairing Mode after the SSID is available, Tuya-Convert complete the "SmartConfig" and then time out.

tuya-convert v2.4.5
Checking for network interface wlan0... Found.
Checking UDP port 53... Available.

When I put the device in pairing mode before starting tuya-convert here is what it happens:

I had exactly the same issue for 3 of my 5 devices ...
With the apconfig.py script listed on the comment linked above and a manual connect to the device in AP mode it worked perfectly. Somehow forcing the device to reconnect to the AP seems flawed and unreliable.
Using the procedure listed above make the process way more robust, obviously.

where can i get appconfig.py? I don't see it in tuya-convert folders

[MacSass]

Hi,
appconfig.py is not yet part of the official tuya-convert.
If you check the comment mentioned above: #966 (comment) you can find it in the commits:

Good luck, it worked perfectly for my devices that I had not been able to flash for weeks trying everything I could think of!
