Hey guys Just letting you know I managed to fix the problem I was having downgrading the console. The guys over at maxconsole suggested a few things, one of which worked. If you have a read up of the post I made on http://www.maxconsole.com/maxcon_forums/threads/287549-Downgrade-fatal-error-0001001 Basically the error is occurring if you have not upgraded your 3DS OTA via wifi. I had only ever updated my console through game updates. All that was suggested was to download 3DNUS: https://gbatemp.net/threads/3dnus.376488/, download a later version of your 3DS firmware as cia titles. Then you install all of these titles to your sysnand. As I say, check out the post but: BE VERY CAREFUL I DO NOT SUGGEST DOING THIS WITHOUT A HARDMOD! You could brick your console.
