I installed unlaunch and Twilight menu and it was working fine. I was tweaking with it and I accidentally set Twilight to automatically boot to last rom played. That was a mistake because I'd never played a rom on it. Twilight didn't boot anymore so I was stuck back to the stock home menu. Then from unlaunch, I set it to automatically boot to unlaunch, then I uninstalled it by accident. It won't boot anymore now! I let it drain battery then charged it and tried again, still no luck. I tried starting again from dsi.cfw.guide/installing-unlaunch.html but it still won't boot when I reach step 5 of "Preparing your SD card." I also heard to try holding down y so I did as it was booting, after it was booting, and before it booted, and nothing happened. What do I do now?! I have a NAND backup on the SD card BTW. I read that there could be an unrecoverable brick but there HAS to be some way, right?
