Sorry Willo isnt that the way to do it....make a backup file onto a USB stick from the all set up box,then flash the new box and put the USB stick in with backup file on and go to image manager ?Confused here You flashed the other box which went fine. Why are you plugging in a USB stick in with a backup on it then?
You should be just plugging in a storage drive which needs to be initialised and mounted as /media/hdd and formatted as ext4 R/W.
Sorry mate am i doing it wrong
