I buy cheap led strip Merkury mi-ew020-999w, this strip with new app, very terrible app

Firstly i start connect strip to tuya, but nothing, i open box and check pcb&chip, this is:

In Tasmota Supported Devices Repository i find only for Merkury Innovations MI-EW003-999W LED Strip (MI-EW003-999W)
But my version little bit difference
Text on pcb: JBT-TYWF-KZQ012(2A)-HX REV2.1. Date 20210415
Chip: BK7231-Beken

I try upload tasmota with this instructions:

PCB Model JRT-WIFI-K7Q01(2a)-PZG Rev 2.0 20200107 was not compatible with tuya-convert and needed to be flashed serially. There are two pads for RX and TX on the PCB to communicate via a serial link.
To power the unit, simply plug the attached USB Power interface; no need to solder the VCC and GRND connections. To put the device in Flash Mode, simple press the onboard button while powering-up the device (Plugging the USB Connection)

And nothing, my pc can’t find ESP (i used usb programmer CH340G, and online app for flashing, and tasmotizer)

I would recommend doing some research on this forum, Youtube and other home automation site to learn about different MCU chips in these various IoT device. Real Tasmota is a firmware package for ESP8266 and ESP32 MCU devices, OpenBeken is firmware for the BK7231 and other similar MCU’s. These are very different chips and flashing the wrong firmware on a wrong chip may make ‘brick’ the IoT device. Within the Merkury line of IoT devices, there are different MCU’s in different devices, can be very frustrating and may even make it impossible to install alternative firmware. Good hunting!
