# Flashing the firmware
1. Erase flash memory:
Connect 3,3V while button pressed to enter flash-mode:
Connect 3,3V while button pressed for about 10 seconds to enter flash-mode. Then release and run:
`esptool.py --port /dev/ttyS0 erase_flash`
```bash
# if using Raspberry Pi 1/2 use
# esptool.py --port /dev/ttyAMA0 erase_flash
# if using Raspberry Pi 3 use
esptool.py --port /dev/ttyS0 erase_flash
```
You should see output like this:
```bash
➜ ~ esptool.py --port /dev/ttyAMA0 erase_flash

7. Setup Wifi:
Reboot your sonoff after flashing(toggle power wire) and run a command
Reboot your sonoff after flashing(toggle power wire) and connect to serial console via miniterm:
