Hacking An exception occurried ARM 11 (core 0) Data abort

Right. I'll try explain best I can.

I've hacked this 3DS before with an Emunand and I was hoping to change it so it was on the system nand. I was following this https://3ds.hacks.guide/ guide, I figured it would be ok on an already hacked 3DS with an emunand because it said
"If you have already hacked your 3DS before to get an EmuNAND setup, and would like to move the contents of your previous EmuNAND to your new SysNAND CFW, you should follow all instructions and restore your existing EmuNAND when prompted once you reach Finalizing Setup."
Though I didn't get to the finalising setup part... and to be honest I can't remember exactly what hacks I used before as it was some years ago.

I got to this page https://3ds.hacks.guide/installing-boot9strap-(safeb9sinstaller) At Section III - Configuring Luma3DS

So after Section III - Configuring Luma3DS when I boot now.. I just get https://www.dropbox.com/s/0nqx0q3mp0fw5i5/20200221_112924.jpg?dl=0 ... So that's not good. I've figured out if I delete config.bin from Luma I can get back to the Luma configuration menu but then it just happens again if you change anything. (Or don't)
I think the best news is I can get to my Emunand if I hold L when the SD card is in and so can still get to the homebrew launcher. If you have no SD card in the system just shuts off. But I'm hoping the fact I can get to the Emunand and homebrew launcher at all gives some hope.

I hope this made sense, if there's more I need to explain please ask. I don't really want to try anything else at this point. I've uploaded the crash dumps.

System nand was on 9.2.0-20E It's an Old 3DS XL

Wild guess: You used Menuhax before and this results in a crash while new Luma is loaded via B9S.

Try removing Home Menu extdata

If you do not (yet) want to delete the data, renaming the folder for testing purposes is sufficient

– or try without SD –

It will only turn on without SD after copying Luma3DS boot.firm to CTRNAND

Thanks, It seems I did use menuhax. Suppose I can now continue the guide. Hopefully no more errors..
