Smart Plug RGBW configuration

Hi,
i bought this smart plug
https://www.aliexpress.com/item/32968895032.html

When searching for flash instructions, i found out, it’s probably this one

I have succesfuly flashed it using tuya-convert with tasmota. I played with several templates, could not find the right one. I decided to swtich to esphome for debuging.

This is my latest config

substitutions:
  dev_name: avatto_plug_rgbw_001

esphome:
  name: ${dev_name}
  platform: ESP8266
  board: esp01_1m

I had some boot problems when i was trying GPIO09 as LED PWM pin. But i managed to recover.
Now, it seems to be bricked after trying the same thing with GPIO14. It does not ping.

I also did no manage to find the power monitoring chip, yet.

So i guess, i will have to pry it open. Or is there another way to flash it again using tuya-convert?

So after two days of cutting and prying the outer tranparent ring, i handed it to my wife and she found, that it has hidden screw under the front plate. Thanks.
It has two PCB’s inside, i don’t see any empty pads for RX,TX pins yet.
