I mean, it really isn't as complicated as it sounds. If I can do it, with hands as shaky as mine... Well. Anyway, finding a 3.60 Vita is often more work and costs more, which is why I dislike that option.
What?! That's not bricked at all. Just buy games at least you can play 3.61+ games legally. They're really cheap or if you still want to pirate, either sell that one and get a new hackable vita or get a 3.60 mobo. Your choice. Also, you shouldn't have connected it to a wifi. Oh well, what's done is done. At least your console still works.
