I've updated Luma3DS with Luma3DS Updater fork from 3ds.guide to stable Luma 8.0. When the updater asked me, I've checked the option to allow copying to CTRNAND, everything went fine and I've rebooted my 3DS. However, when it turns on, it instantly shuts down. It doesn't even stay on for a second. When I turn it on, the blue LED indicating that it's on quickly flashes and then it stops glowing, so basically the 3DS turns off. When I try to hold SELECT on boot nothing happens. Payloads won't load. Now I can't do anything. I've got a New 3DS with B9S 1.0 installed. What can I do?
