Serial flashing the device with Tasmotizer
Carefully solder wires to ESP8266 chip and connect to appropriate pins on USB-to-TTL converter:
| USB-to-TTL | TYWES3 |
|---|---|
| GND | GND |
| +3.3V | 3v3 |
| TX | RX |
| RX | TX |
Do not use 5V! It will damage the chip.
Then connect another wire to GND and manually hold it on GPIO0 pin, then connect USB adapter to computer:
Device is ready in the flash mode and you can easily flash it with Tasmotizer. After that, gently unsolder the wires.
