Is there anyway to get back to completely unmodified 3DS full stock firmware after following plailects guide? I'm pretty sure I made some sort of backup following the guide. I was on 4.5fw when I started the guide but after installing everything in the guide I updated my system firmware to the current. I'd like to go back to the stock 4.5 firmware I was on before I did all the cfw and stuff. Any ideas on a step by step tutorial to get everything back like it was out of the box?
