I'm not really good at searching through gbatemp threads so thats my bad. I'll keep your advice in mind for future reference. Other than not updating my firmware, I've kept my other software apart from NTR (as I don't use it) up to date. Thanks!
Just wondering whether or not 11.9 is safe to update from 11.7 on a New 3DS XL with Luma CFW 9.1. I haven't thought of updating until this point just out of pure superstition.
