echo Before you begin please make sure your Flipper Zero is plugged into your PC.
echo Then on your Flipper Zero open the GPIO menu and select USB-UART Bridge. In
echo the USB-UART Bridge config menu make sure the following configuration is set:
echo - USB Channel = 1 (on newer firmware)
echo - Baudrate = Host
echo - UART Pins = 13 and 14
echo - RTS/DTR Pins = None
echo.
echo Notes:
echo - Temporary installation files will take up approx. 3.5GB of storage space.
echo - You will have the option to delete the temporary files on completion.
