Evening (or morning) fellow 3ds owners! I have been wanting to purchase a gateway (no flaming about brick code etc etc), but as my two 3ds' are on 7.1 firmware, you can see the dilemma. Now, I have searched on Ebay and I don't really want to pay for another complete 3ds. I have come across a motherboard that is supposedly on a 4.x firmware. I have my nice shiny red Pokemon X and Y xl that I was considering putting this in. How hard would this be to accomplish? I know there are a lot of flex cables inside of it that obviously cannot be damaged. So yeah. tl;dr: How hard would it be to swap motherboards? And would it be worth it to do it to a limited edition 3ds xl?
