I tried to install gateway 3ds omega 2.3b on my 3ds console, after I backup system nand and format system nand, I connect 3ds with internet to have a system updating! But there is something wrong, I failed to update to emunand 8.1. Now I want to recover system nand into my 3ds console (I have a nand.bin file on my computer), but I don't know how to operate! Could you help me?

Stop right there, criminal scum!
