So i purchased these Teckin SP22 (USA) smart plugs with energy monitoring early in 2019 but discovered I was too late and they had the updated firmware that couldnt do OTA. I tried cracking one open and soldering to it to flash over FTDI but there was some flubbing and it didnt work right, not sure what went wrong.

Anyway I still have one good one and heard that the new Tuya Convert can handle them now. (these are not the new Teckins without an ESP chip).

I am using a new SD install of raspbian buster lite with a Raspberry Pi 3 B+

I followed the instructions in DigiBlur's new tuya convert video and I got to the point where it said "Successfuly found device on 10.42.42.42 and started a backup but it took a long time and i noticed it wasnt showing any transferred bytes so i CTRL-C'd out and rebooted. But now when I plug in my Teckin device I cant get it int othe flashing mode. It looks like the firmware has been modified as when i plug it in the LED blinks (somewhat unevenly, like it's trying to blink steadily but sometimes misses a beat), and eventually it stops blinking entirely!


I tried multiple times to get the ./start_flash to work again but it seems like it cant get the device (smartconfig retires infinitely).

I don't know when the logs are generated, or overwritten, but i attached the logs i have on hand. They may not be the logs with the attempt that failed to do firmware backup

the firmware backup is 0 bytes by the way

Is the device bricked?

False Alarm, after banging it around and plugging and unplugging a ton it i got the device to be discovered!!!

Now i have two perfectly usable, secure, private devices! Thank you Tuya-Convert maintainers!

So, maybe this was misleading. I actually haven’t flashed the original device i posted about (the first one to get stuck). I have successfully flashed the second device (the one i originally cracked open and then posted the screenshot of since it still had the original tuya firmware). I am still attempting to get it to flash but it looks like it can’t find the device.
