https://plailect.github.io/Guide/installing-arm9loaderhax So, I'm following the guide in the link above. I've gotten everything set up until step 6 of section III, where it says to update the system firmware through settings. Every time I try to update my 3DS, it tells me it can't update. I also tried restoring my NAND as the guide suggested (Hourglass9 tells me it's successfull), and it still gives me an error when I try to update (for the record I tried to update from my 4.2 backup after restoring sysNAND because the guide wasn't clear if I had to go back to 2.1 again). Is there another way to go about this? Do I need to go back to 2.1 before attempting the update again?
