I'm using a Raspberry Pi to slash the firmware. I find this simplier that using a USB TTY device plus I also have a number of Raspberry Pi's lying around.

Prerquisite

Install PIP

apt install python3-pip
sudo pip3 install esptool

Change Config Files

Serial device --> /dev/ttyAMA0

cmdline.txt

 vi /boot/cmdline.txt

delete 

 "console=serial0,115200"

config.txt

 vi /boot/config.txt

add 

 "enable_uart=1"


Flashing

Display Existing

 esptool.py --port /dev/serial0 flash_id

Backup

 esptool.py --port /dev/serial0 read_flash 0x00000 0x400000 sonoff-image4M-stock.bin

Erase

 esptool.py --port /dev/serial0 erase_flash

Flash

Here I'm downloading the sonoff.bin file from thehackbox but writing the file as sonoff-6.7.1.bin. At time of download the version has probably changed, so write the file as per the correct version number so you know which version of the file you have. 

wget http://thehackbox.org/tasmota/release/sonoff.bin -O /home/pi/Downloads/sonoff-6.7.1.bin

esptool.py --port /dev/serial0 write_flash -fm dout 0x0 /home/pi/Downloads/tosmato-sonoff-6.7.1.bin


Configure

Once the firmware has been upload you will need to connect to the Sonoff device via a custom SSID that the device is now advertising. The default IP is 192.168.4.1

Log onto the device using the Raspberry Pi. Connect to the WEB console and then issue the following commands to configure your device. Just configure the Wi-Fi settings for now to connect to your network. Once changed you can then do the rest of the configuration from any other computer on the same network.

Log onto the web interface of the sonoff device. Frro Main Menu, Console.
