Soul Poet,
good description, that is pretty much the best way to do that right now.
Obviously you meant in step 1 to place the original in the xbox (not the x360)
the tool is moogui available
here.
also important that everyone realizes, that for now, no method seems to work for everyone.
So until QWIX and or craxtion do a tool for this, it might still be a bit hit and miss whether it works or not for you.
If it does not work for you, then you can still use your samsung Drive with xboxcreator to easily do a DL backup (IMG:
