I discovered this problem a while ago, but never really bothered to fix it because I don't care about this particular system all that much. It's a 9.2.0U 2DS that's been from Menuhax to arm9loaderhax to boot9strap. The "brick" seems to have happened after installing B9S using the Holy Guide. I got stuck when the guide told me to configure the CRTNAND Luma thing, because without the SD card, the system powered right off. I was able to boot the system with the SD card inserted, but it froze. The home menu seems to load (the Wireless Communication LED lights up), but I got nothing but a black screen. When I pressed the power button, it takes me to the regular power-off screen. Recovery Mode does work, and I can also boot .firm payloads and the Luma config. After PMing someone, I was instructed to follow "black screen on boot" in the troubleshooting guide. I enabled exception handlers, and now the system boots to this: An exception occurred Processor: ARM11 (core 0) Current process: menu (0004003000008F02) (bunch of junk) You can find a dump in the following file: dumps/arm11/crash_dump_00000003.dmp Press any button to shutdown EDIT: And no, I do not have the recent B9S update or Luma 8.0.
