Where do you see the system version you are updating to?oh gosh.......
waaaaaait. I tried to share my Mario Party cart from Gateway SYSNAND 4.5 to Gateway SYSNAND 4.5 and it asks me to update to 6x
If it is like you said, I should then use one of my 3DS (which is on 7.1) downgrade it to 4.5 and then do it?
