I recently downgraded one of my old systems to 2.1 to get the OTP and use Arm9LoaderHax. I was able to restore my sysNAND from my backup, but when I went into HBL to boot EmuNAND9 to then restore my emuNAND backup, It first flashes a red screen, hangs for a second, flashes another red screen, and then kicks me back to the HB Menu. Booting Decrypt9 also does the same thing. I also cannot boot into any sysUpdater of any sort, like sysUpdater to downgrade <=10.7, or PlaiSysUpdater. If anyone has this same or similar problem, please reply if you have any suggestions of what I can do to fix this. Thanks!
