Hi, I recently installed cfw in my old 3ds. While installing the home-brew it from download play it crashed and when I tried to boot the following error appeared. 'An exception occurred Arm11 core 0 data abort. I have already tried some many things to no avail, including deleting and replacing boot.firm and all essential luma files. I have tried disabling arm11 by pressing select and I have also tried the ctrtransfer using the old 3ds file, Nothing so far has worked. I can boot up gm9 with no problem. Any help is appreciated.
