how is this possiable if i block or leave wifi settings blank with my current set up i wouldnt be able to accss the gateway web paige
last question for now should i re link the nands (if thats even possiable) or keep it how it is now
Well first of all when you use the exploit to boot to emunand, sysnand will not download an update. Because you are talking about downgrading I assume you have a o3ds. The wifi switch on the side will disable wifi. You can also block the update servers using a variety of methods. Directly on the router, openDns, a proxy, whatever floats your boat.
Sysnand is dead to me so really don't care if I screw up and put it in sleep mode and get and update. I just reformat sysnand and it goes away. There is also some button combo method that I have not tried yet but will next time.
What you really need to be careful with is leaving the house and running into an att hotspot or a Nintendo Zone. It doesn't matter If you have connections set up or not, those bastards will connect without your permission and download it. Only way to prevent it is with the switch.
I never had an 4.x exploit so I won't answer those questions.
Ds games need a da mode flashcart. Blue card, r4, dstwo etc.
I have heard some say it is tricky going directly from 4.x to 9.x. So look into that before you try it.
If you really want to start experimenting I suggest you get a hardware mod so you can easily go back is you F It up. Get it done on your timetable instead of after the F up.
