## Upload Tasmota
### Put device in firmware upload mode
When performing a firmware upload do **not connect the device to AC** but use the power supply provided by your (FTDI type) serial interface.
Put the device in firmware upload mode by grounding pin GPIO00 while applying power.
Grounding pin GPIO00 can often be achieved by pressing button 1 on the Sonoff device or using a wire between GPIO00 and Gnd if the button is not available. Deviations may apply.
Connect the serial interface of your PC to the device while GPIO00 to Gnd.
Esptool uses the serial interface to communicate with your device. On Windows these interfaces are named COM1, COM2 etc. On Linux these interfaces are called /dev/ttyUSB0, /dev/ttyUSB1 etc.
Before using Esptool make sure you know to which serial interface name your device is connected to.
In the following commands I use COM5 as an example.
