I have a 3DS and it is jailbroken with Luma3DS but now it won't work, it flashes white for a second when I press the power button and it won't start up. I'm the one who was stupid and didn't think clearly, what happened is that I formatted the SD card without deleting the CFW on it and used the SD card on the Nintendo Switch Oled. Since I only have one SD card and not a new SD card until next week or the week after that. It won't start even without an SD card in it.
