Hi all,
Is there any link for a good idiot proof guide for downgrading, what a sys/emunand is? I'm totally green, everytime i read about linking, unlinking, system format, losing saves, re-installing all eshop content it makes me just scared to try. And the amount of chaos in the threads since the first wave of downgraders doesn't help.
You won't need to focus on Sysnand and Emunand just yet, since you're only at downgrading stage.
You won't be able to create emunand, if you don't downgrade to 9.0 - 9.2
Downgrading:
1. Look for the files for your region.
2. Use safesysupdater to check those files.
3. Once above check if confirmed to be correct, proceed to downgrade.
To get to the stage whereby you can use safesysupdater, there are tons of guides out there.
Sysnand and Emunand:
They are terms coined to represent System Nand, and Emulated Nand, whereas nand is a sector/chip on your 3DS with up to 2Gb of memory, for storing various important things,
including the operating system and updated operating system of the 3DS.
Emunand is basically a copy of your sysnand, which involves the partitioning of your SD card, and emulating the nand off the SD card.
Once you reach the point where you created your emunand, you can use a different theme or folders to represent which is which,
and do a "system format" on your sysnand or emunand, depending which one it is you want to keep.
Also, at every point in time, back up your Sd card and your NANDs, so that you can restore it.
