I did a hardmod on my N3DS XL. I soldered the SD adapter to the required points. From the beginning I was already throwing a blue screen with an error: 00F800FE 00000000 00000000 00000400 00000000. From what I understood, it was normal. I was able to dump the nand a few times, verify that they matched via the nand checker. I then attempted to downgrade it. I flashed the nand, installed the files to the SD card. Now I needed to boot the device. Here is my issue, I have always had the blue screen error code. It is still there and I cannot boot the device at all to continue the downgrading. I have checked my solder and they are all good. I even got to the point where I removed all of the wires from the hardmod just so that I can see if it boots, still same blue screen. What do I do from here?
