    I have a problem with my 3DS XL...

    I don't know why but I can only use it with the 4.5 FW.
    If I upgrade the console, it will not boot (black screen)

    I have a USB NAND Mod so I can write my 4.5 NAND back but if i write any 4.5+ NAND (for ex my 9.2 NAND) the console will not boot.

    I have updated from 4.5 to 8.0 with smash bros retail game and now the 3DS doesn't boot so I have to write my 4.5 NAND back...

    Do you know what it the problem?

    Thanks a lot

    EDIT: sorry wrong section
