I have a New 3DS XL, and I tried to downgrade to 9.2 using DSiWarehax. I deleted my home menu extdata but every time I power it on when it's on 9.2 it gives me "an error has occurred, please power off your console" or something like that. The general consensus for solving this issue seemes to be formatting your 3DS System Memory, but I have a few questions: If I backup my entire SD card and then format my system memory, then restore my SD Card backup, will I lose any of my data? (Save Data, Games, and such) Or will I have to get back everything? More questions will probably arise later, this one is the main question I want answered right now.
