The method on the 3ds.guide is the best one. There you will see everything you needI only have one question (and forgive my low knowledge on the matter please). I have the arm9loaderhax installed on my o3ds but i want to know how can i check to see if i have everything i need to update to the boot9strap (if it is the same as the sighax) and what kind of method is the safest/best to update.
