Tried to install CFW on 11.2 using the downgrade method, but forgot to make a NAND backup to revert to. (i know, im an idiot.) So, now my 3DS was at v2.1, with pretty much 75% of all my data being unsupported. (apps, themes, etc.) I thought there was no road to turn except just start over, so I formatted my SD, and then did a system format. Then, when the format was finished and I tried to boot on the system, the blue light appears for 1 second, then fades off. I have tried everything, all "recovery mode" methods and such, but nothing seems to work. Is there any way out? Or should I ship it to somebody? (or Nintendo) Please don't call me an idiot/dumbass/etc. I'm new to this stuff. All I want is my 3DS to successfully boot. I have learned my lesson.
