TUYA-CONVERT was developed by Michael Steigerwald from the IT security company VTRUST (https://www.vtrust.de/) in collaboration with the techjournalists Merlin Schumacher, Pina Merkert, Andrijan Moecker and Jan Mahn at c't Magazine. (https://www.ct.de/)

======================================================
PLEASE READ THIS CAREFULLY!
======================================================
TUYA-CONVERT creates a fake update server environment for ESP8266/85 based tuya devices. It enables you to backup your devices firmware and upload an alternative one (e.g. ESPEasy, Tasmota, Espurna) without the need to open the device and solder a serial connection (OTA, Over-the-air).
Please make sure that you understand the consequences of flashing an alternative firmware, since you might lose functionality!

Flashing an alternative firmware can cause unexpected device behavior and/or render the device unusable. Be aware that you do use this software at YOUR OWN RISK!

IMPORTANT
1. Connect any other device (a smartphone or something) to the WIFI vtrust-flash
   This step is IMPORTANT otherwise the smartconfig may not work!
2. Put your IoT device in autoconfig/smartconfig/pairing mode (LED will blink fast). This is usually done by pressing and holding the primary button of the device
   Make sure nothing else is plugged into your IoT device while attempting to flash.
3. Press ENTER to continue

It is not entirely clear why the process is failing unfortunately. The device seems to have connected, the PSK was generated successfully, and the device made the proper registration calls.

It did not respond to the upgrade command, which suggests only that the command has changed or some other validation was implemented in a newer firmware.

If you have the ability to flash by wire, please make a backup of the stock firmware first, that we can use to understand what is happening under the hood.

[tarkin2020]

thanks for feedback. do you have some instructions for the wire backup? I can try to do it. regards

[kueblc]

The Tasmota docs include a tutorial for the hardware prep and subsequent backup and flashing using esptool.py and an FTDI or similar USB to serial device.

I had the same problem and flashed mine manually. Here is a backup of the firmware https://zebar.de/owncloud/index.php/s/Ky9D2GwKAcjAmwH
