Got Jelly Bean to my Galaxy Note 10.1 today and want to update. But I'm a loser in the field.... Samsung's page says like this about updating: 1. Backup 2. Factory reset 3. Update 4. Factory reset 5. Restore the backed up stuff All this factory resetting... doesn't that wipe apps and stuff away, or is the entire device backed up in Kies? Other guys have said that they just updated, without any factory resetting. What's the difference?
