Hi everyone, From previous post, I did 2.1.0 ctrtransfer and installed a9lh but now I want to undo and unstall a9lh because now I can't run gateway with NVRAM (through settings and profile method). I had 4.3.0-10U O3DS and I want to revert back to how it was. If there is a factory reset, I would do it as long as o3ds is lower than 4.5.0. Right now, when I take my SD card out, 3DS doesn't boot up. Before 2.1.0 ctrtransfer and a9lh, 3DS booted up fine without SD card. But my main reason is that now, I can't run gateway and I want o3ds back to way it was. Is there a way to revert back?
