Hi, i have an O3ds that i finally found and it has 7.2.0 on it. I want to install the CFW Luma 3ds on it, but i have never done this before. Do i have to upgrade it to 9.2.0 in order to put luma 3ds on it or can i stall on 7.2.0? How do i even install Luma 3ds on it in the first place, haha. I haven't done anything to the o3ds, i just finally found it and luckily it had 7.2.0. can anyone help? Thanks.
