Hacking Gateway won't boot after chaning my SD card

[MASAMASA]

Hello,

I just got a new SD card (8go) for my 3DS, and wanted to swith from the old SD to the new one.
So I backed the content of the old one on my computer and put it on the new one.

But now when I try to boot the gateway from the sysnand (my sysnand is in 4.5 and I use the DS profile exploit), the gateway logo appears and the console reboot on sysnand instead of emunand. If I repeat the process, I get a message of error from the console and have to turn it off.

The new SD is formated in FAT32 and I copied every files that were on the old one (wich booted normally right before the copy), I even changed the name of the SD to GATEWAYNAND. I don't see where the problem comes from...

Does anyone know how to fix this?

thanks in advance.

You didn't create and transfered emunand to the new SD card.

You need SD card prepared for NAND partition.
Format EmuNAND with GW menu on new SD.
Extract EmuNAND from old SD card and inject NAND.bin to new one.

Be careful because when you format emunand, it erases the contents of the SD card so backup first.

Thanks! I had no idea about this process. I was afraid because I formated my first SD, but after copying back the content on it, the software was still able to extract the nand.
It works fine and I won't have to repeat the process now that I have 8Go in my 3DS!
