This isn't quite what the title may seem to say. My main 3DS (which is a 'New' never had cfw and is currently on 11.4. However, I have another ('Old') 3DS rotting somewhere and hopefully still works (been 8 months at max since last use) and it is past 9.X. Probably at 10.X. So I have been wondering if I install LumaCFW there using SafeHax (I think), could I somehow transfer it to my new one? Say a sysNAND backup I make on it. Could I restore it on my new one somehow so it's on a lower fw version at least. Note 1: I don't know anything about the cfw on 3ds except for the fact that it cannot be installed on 11.4 at the moment and I partially doubt that there will be another safehax on it (or fasthax) Note 2: I really don't give a crap if I overwrite my save data regarding streetpass or downloaded games, but if I can do something that could keep it, I would appreciate it, but don't focus on that when replying Note 3: REPLY WITH A NEWB-FRIENDLY ANSWER!!! This is what I get for my acquiescence towards Nintendo's update prompts.
