1) Download the correct image[2]

2) Verify the image against [1]:

sha256usm $IMG_FILE

3) If the sha256sum matches:

scp $IMG_FILE root at

4) ssh root at

5) cd /tmp

6) sha256sum $IMG_FILE

7) sysupgrade -c $IMG_FILE

If you want sysupgrade to download and install the image for you (high

1) ssh root at

2) sysupgrade -c $URL_OF_IMG_FILE # See [2], make sure that there are
no new line or spaces in the URL.
