I have a new 3DS EUR on 9.2. I made a CTRNAND backup on my new 3DS XL USA since it isn't functional at the moment. I then injected the CTRNAND into an emunand of the new 3DS. It wouldn't boot, so I used the original SecureInfo_A from sysNAND. Leaving it at that just um.. gets me to the test menu? I never enabled this through Config, I haven't even USED config in months. It doesn't seem to boot after changing the region of the secureinfo, as well.
