Okay. There are two 3DS's Il lable this one as "purple" 8.1 old 3ds Il lable this one as "red" 9.3 old 3ds My sister owns Purple. I own Red. I want to swap motherboards so I can have exploitable firmware on Red Red has a broken card reader ( broke it atemping to nand mod ) How should I go about doing this without my sister knowing? I will facory reset Red MOTHERBOARD so she doesn't know I switched it(If she loses her data I will say it was because she didn't charge it for too long) In the end I want the RED shell to have 8.1 I want Purple to be on 9.3, but I dont want it to have the broken card reader so she notices.
