I read somewhere that if you inject a emunand into a sysnand, it will be a guaranteed brick. However, later on, it was stated that only happens if the emunand was upgraded from 4.x to 9.x. Here is my situation: I am trying to be able to use RAM dumps and AR codes and such, and I have upgraded my 3DS' sysnand to 9.2 via my friend's Smash Bros card. Game card updates don't include the browser though, bringing up the need to install it as a spoofed cia. I have a formatted emunand like the person in the forum said, to make it safe. Installed the cia and extracted it. I need to make sure this is safe to do though. There are no other changes besides that. A: Can I inject this emuNAND into my sysNAND safely? B: How exactly do I restore a sysNAND backup? I have downgraded before with Gateway, but I don't see an option to restore a NAND.bin anywhere. How do I go about restoring my old 4.x backup if needed? Any help would be appreciated!
