EDIT: IT WORKED! YEAH!! Thanks to everyone who helped! I bricked my 3DS XL! Yeah! First time for everything. So, I have 3 GateWay NAND backups of my system, and I'm looking to write them onto the NAND via a NAND mod. I've got a friend who is very good at soldering, and I'm just looking for a good tutorial. I found this. Let me know if it's good or not. Part 1 (Setting it up) Part 2 (Computer stuff) If you have any other video tutorials (or written tutorials), please let me know. Thanks!
