Hacking ARM11 Exception Occured Prefetch Abort/Kernel Panic

[TomFoolery]

Alright, so here's my situation. After installing cfw on my N3ds xl, I've attempted to use a variety of home brew. Unfortunately all of them seem to end up resulting in an ARM11 exception occurred error, at random times. Hasn't really happened to me when trying to boot the software, but eventually occurs after trying to use it for a few minutes. This has happened in Anemone, mGBA, SNES 9x 2010, pretty much everything I've tried. I'm running Luma3DS 9.1-89cc6ed, and my system software is 11.7.0-40U. I followed 3ds.hacks.guide to install cfw. I've also looked to other peoples posts to cross reference and possibly find some solution, but I can't seem to find anything that's replicated my issues. I've also saved a few of my crash dumps if those will be of any use in figuring this out. Any help is appreciated, thanks.

Copy everything off your SD card, reformat in FAT32 + 32KB cluster size, and full Write + Verify the empty card in H2testw.

Check your card for hardware issues.

@TurdPooCharger I did as you said. Test came back completely fine, no errors found. Any other suggestions?

1. Battery trick.
2. Clear Home Menu extdata.
3. Backup your legit tickets + CTRTransfer + Update 11.9U + restore legit & fake tickets.
   • Help with Tickets deleted [Post #2]
   • There's also restoring the SysNAND but only if you never did System Transfer or Format System Memory since making that *.bin NAND image.

@TurdPooCharger Did the battery trick and cleared the home menu with no change happening after doing so. Went ahead and followed all the steps with option 3. Only thing now is that all my home brew I had installed is gone except for the home brew browser. Do I just reinstall that software again? Apologies on my stupidity, I only really went over the basic installation a few months back and as soon as I had these problems I just set the system aside for a while.

In the third point, there's the first bulletin that talks about backing up and restoring tickets. Check for titles with missing tickets with greyed out X's in System Settings → Software.

I had the same issue and user Giodude (on another post) suggested placing boot.3dsx in the root folder of the SD Card. Hope that helps. It may also be another missing file.​
