first you have to flash the "notfall" image (orig. fw 1.03, ... 6 files) maybe with the tool (i don't testet it, i'm only making changes by hand!!!)
theres no "notfall" 1.02!!!
if you had done this and you like the original 1.03 you've finished!!
if you want more...
after that you can normaly flash the 30.06 or 10.07 sf-image (4 files) by usb-stick!
best regards...
