About 5 years ago I had just installed CFW for the first time onto my n3ds xl and was enjoying all the new games that inevitably came with it. My brother asked me to install CFW on his o3ds so that he could emulate some old GBA games. Long story short I had accidentally loaded the backup for my n3ds xl into his o3ds and deleted the original 3ds folder for his o3ds and proceeded with the installation of arm9 for my n3ds xl onto the o3ds and now the o3ds will not turn on. You can press the power button and the light will turn on, but the screen will not turn on. The only thing I can think of that might work off the top of my head is the find all of the original files for any stock o3ds online and basically reprogram the BIOS on the motherboard to force it to boot, but I have no idea how to do that. I do not have the files such has the 3ds folder or dcim or anything for the sd card that was in the 3ds and so far I have been unable to find them online. Please help me.
