okay thanks sonIf you put the motherboard of a 4.5 3ds in the shell of your 3ds then yes it would be 4.5. That is basically just a shell swap.
gonna buy a motherboard off ebay and just swap itWhy not just use the 3DS that's on 4.5 in the first place? O.o
Are its screens broken or something?
thanks homiehonestly it isn't that hard (in the means of , you don't have to solder). the hardest part is the screen ribbon in the right shoulder.
