I've wanted to update to the latest system update on my emuNAND but I think the rainstorm outside scrambled the update which made it take a few seconds to download instead of a few hours. I can still turn on my 3DS but when I select CakesFW and boot the CFW the screen stays black without booting it. Is there anything I can do to restore it? I don't want to lose hours of progress on Monster Hunter. I'm not sure if I made a recent backup or not.
