My wife has an old purple 3DS that she doesn't keep up to date. She hasn't even connected it to wifi in months. I just checked, it has 10.7.0-32U. Assuming I got her permission, could I apply CFW to it? And would it be reversible? I would primarily do this with the intent of using the DS exploit to add CFW to my own which is on 11.0, and I doubt she'd want a permanent change. I also need to know any risks before I ask her to let me do this. Edit: Besides the obvious risk of potentially bricking her 3DS, which I need to know the odds of.
