    Hello,
    My friend has updated his Switch to 9.0.1 and after he recognises that the games are running slowly, he had restored NAND with Hekate to a earlier firmware. But now the Switch has just a blackscreen after trying to boot with SX, Atmosphere.
    Any help please?

    how did he update his switch?
    Via OFW or via Daybreak/choj?
    Edit: forget the above: Did he restore even boot0 and boot1? Or just rawnand.bin?

    Were the boot 0 and boot 1 from the same firmware version as the Rawnand?

    First off, why would downgrading make games run faster? Secondly, how is the SD card formatted?
