    Ok i got another question here. Right now i am working on gettign otp for my n3ds and I am backing up my system naND AND EMUnand. Atm my system nand size seems right but my emunand size is like 600mb smaller. I remember my o3ds where all the nand size is the same.

    Actually, to be exact, my sysnand show the size of Toshiba NAND while my emu nand show the size of Samsung NAND

    Have you looked into the troubleshooting guide?

    so u write the small emu nand into the sys nand no problem.

    yes, as long as it size matches any of the of the nands. if its different than any of them then dont flash it.

    Also, as long as the sysnand is bigger than the emunand, you're fine. If it was the other way around, then you'd have an issue (I highly doubt this would ever happen unless you really didn't know what you're doing).

    Someone pointed out to me the other day that it will use the smallest size now. Which is the 1.2GB Samsung based NAND as the Toshiba one really only uses 1.2GB, just that the rest of the NAND is written in zeros to fill it to 1.8GB. This is normal. You only need 1.2GB for the emuNAND.

    What people seem to be missing here is that the OP most likely has a 1.8GB NAND.
    If you're using RedNAND (as mentioned in the guide) it shaves off the unneccesary portion (with emuNAND being 1.2GB)

    No, we already realise this. Everyone is telling him/her it's fine. OP also stated in his original post that he has Toshiba NAND - which is 1.8GB

    @Xellos2099 The guide was updated to use RedNAND, essentially it's a minimal image of your NAND which may not actually fill the whole NAND chip (there's an option for backing up sysNAND in Decrypt9 called minSize that does the same thing). It's perfectly fine the that sysNAND backup is not the same size as the emuNAND backup. It's not listed in the troubleshooting section because it's not an issue.
