By the way, I have not yet hardmoded nor downgraded my N3DS nor O3DS before because I currently do not have all the materials as of yet (And yes a soldiering iron is required which I do have).
Well, I stand corrected from you. There is a way to downgrade without hardmod. Anyway it is better if you do hard mod it because this would help you out if you brick your 3DS (extra precaution). Well I guess I need to do more research.
