A quick reply for you.

After the "fast" command you must change the terminal's baud rate to
115200.
With mincom type CTRL-A then P. Select from the list

After the "rx" command you should start sending the image from your
terminal to the device.
You can do this with mincom by selecting the CTRL-A S key sequence and
then pick xmodem
from the list type in your file name and you should start sending data.
If this does not work first time keep trying a few times.
It often works on a second or third try.

I am assuming that you are using minicom from linux.
