You would have to back up your NAND with a hard mod as there is no homebrew possible (yet) on a 2DS. Even then, nobody has documented the pinouts on a 2DS. There really isn't much reason to back up the system at this point anyway.i was wondering how i use the NAnd back up i have a R4i 3ds v 3.3b i also have the r4i deluxe gold that i bought by mistake for my 2ds how would i back up my NAND ?
I apologize for necro-ing this thread, but I have a relevant question:
I used the latest Gateway launcher to backup my 2DS' 9.2U sysnand. Am I able to do anything with it, besides hold onto it? Is it pointless to keep it? I don't have any kind of 3DS flash cart yet, but I'm both curious and hopeful about getting an emunand working on my 2DS someday.
You can do many things with the backup NAND.bin.
1. You can create an EmuNAND partition with it. This is useful if you, for instance, downgrade to 4.5 and want to use EmuNAND with your backup.
2. You can restore your SysNAND using your NAND.bin, by going into the Gateway menu, by holding up when going to the downgrade menu. This is useful when you format your SysNAND, or downgrade / upgrade and want to get it back.
DO NOT delete your NAND.bin. If you completely mess up your console by bricking it, you won't be able to ever get it back to normal, and you might as well throw it away. At least if you have the backup, you'll be able to do a hard-mod and get your stuff back.
