After firmware flashing finished the sensor is down off about z03mmc

You can easily restore it via UART. Just follow this paragraph https://github.com/devbis/z03mmc#flashing-firmware-with-usb-to-uart

You may also refer to https://github.com/atc1441/ATC_MiThermometer/#usb-to-uart to write either BLE or Zigbee firmware.

Both TX and RX are connected to the same test point. But TX with 1kohm resistor.

RST is not connected in my case while I don't have it on UART

Thanks!

@devbis one q, I see txd pin at board, but where is rxd? According to image of xiaomi lcd board...

@devbis Are there any differences in the boards or problematic revisions?

For example, the first photo is my board, which went down after the firmware, the second photo is Nikolai’s board. They are really different, judging by the pins on them.
