I picked up a half-broken o3DS this week for the purpose of downgrading other systems. The cart reader is broken, which I knew about in advance; it should be compatible with Browserhax, so I don't need a cart slot. However, every time I've tried to insert an SD card I get an error saying write protection is enabled. Clearly, it's not, as I haven't moved the switch, and the error pops up with multiple cards that work fine in a 2DS and Wii U. I would assume the SD reader is broken, but does anyone have quick tips on fixing it rather than replacing it? Replacement parts are cheap, and should only take a couple hours to swap in, but I'd hoped to be able to get this done over the weekend. Unless there's a tool for dumping NAND over the network I can't imagine I'm gonna get real far as-is.
