Hi My friend recently bricked his O3DS by installing system cias onto his sysNAND. He made a backup of his o3DS sysNAND using Gateway menu. I'm going to NAND mod his 3DS so I can flash back the NAND.bin he backed up before. However, the file was backed up using Gateway menu. Is there any extra step that I have to do in order to flash the gw nand backup back to his bricked 3DS? Thanks in advance!!!
