Explanation of the issue:
-Used ntrboot on said console to install b9s.
-Disabled Parental Controls, then updated (console was on Ver 3.0.0-6E).
-Installed FBI and homebrew, everything is fine.
-3 days later, ARM9 error apppears every time on boot (Version 8.1.1 stable)
-Made CTRTransfer, installed actual Luma
-Error "data abort" pops up when apps are trying to access Titles (Accesing Data Management>3DS>Software, Booting FBI, except injected, selecting the Titles section in injected FBI, opening Checkpoint)
-Another type of ARM9 error appears, other than "data abort", (When closing System Settings by short-prssing the Power button after accesing a homebrew and closing it, closing injected FBI on a Power button short-press), called "prefetch abort (svcBreak)"

Steps to reproduce:

1. Installing said Luma version on 3.0

2. Update to latest FIRM

3. Atempt to run anything related to Titles. (Ex. Checkpoint)

Can't reproduce the main issues, but the injection issue is known and is a problem of injection itself being well, a dirty hack. You shouldn't use injection any more, it's obsolete.

Issue has been solved personally. Corrupted Title data was found in the SD card. Thank you for your time, and I apologize for the wasted issue. On a side note, injection is used when the 3dsx version doesn't work, as I had several cases personally. This was one of them.

Issue has already been closed, but enable the ARM9 exheader patches in Luma's config, that'll resolve FBI not working properly as a 3DSX in some scenarios.
