Thanks. But it seems to be quite complicated. I'm looking for a very easy method for restoring. IMO, the easiest method would be: "flasher -fF backup-file.bin" on a brand new N9. If it is not possible to create such a "backup-file.bin", would the following scenario be possible: - get new N9 - enable SDK mode - install rsync - "rsync -a --delete backup-server:/N9-backup /" (or similar) If yes, I would do the backup with rsync instead of dd. TIA for any hints, Peter
