I'm wanting to return my 3ds to factory settings so I can return it to the place I bought it from. Unfortunately after installing a9lh I realized that a few keys weren't working properly and the camera also doesn't work. I have all 3 of my emuNand and sysNand back up files but not sure what steps to take to remove it completely if anyone could give me a few steps or post a link to a uninstall guide that'd be great. I have to return it by tomorrow, otherwise I won't be able to get a refund. Thanks
