[Tutorial] - Fixing a bricked system

try to unmount sdcard6 and then flash your original backup again. I think it is umount /dev/sdcarda6 or something like that. Maybe it is not flashing because it is in use. It does say "27553792 bytes (26.3MB) copied, 18.888677 seconds, 1.4MB/s" which seems like it worked though.
