    OK, so the proposed steps for the tutorial would be as follows:

    Code:
    dd if=/dev/rdisk* of=first1024.bin bs=1024 count=1
    Code:
    cat first1024.bin boot0.bin boot1.bin full.00.bin full.01.bin full.02.bin full.03.bin full.04.bin full.05.bin full.06.bin full.07.bin > /Volumes/WhereYouWantToStoreIt/emunand.bin
    
    Write the backup with pv:
    Code:
    sudo dd if=/Volumes/WhereYouStoredIt/emunand.bin | pv -s 29G | sudo dd of=/dev/rdisk* bs=2m conv=noerror,notrunc
    Without pv:
    Code:
    sudo dd if=/Volumes/WhereYouStoredIt/emunand.bin of=/dev/rdisk* bs=2m conv=noerror,notrunc
    Anyone see any issues?

    I've been testing my sh command to dump boot0, boot1, rawnand.bin from the emunand hidden partition. Hope it will work :D

    I'm on a fat32 6.1 emunand on SD.
    Seems a big job to shift this to a hidden partition and if I was to do it I'd probably just back up saves and start with a brand new emunand.. I'd be undecided as to whether to upgrade my sysnand to 6.2 first or leave at 6.1 and upgrade the emaunand offline.

    would you guys say it's worth making the change from fat32 SD emunand to hidden partition?

    When you have emunand at hidden partition and update it to latest fw you must do it offline?

    Also you must have auto rcm for avoid fuse burn or with hidden partition is different?

    Do you think its possible to transfer the hidden partition from one sd card to another? I want to buy me a new, larger one and want to transfer all of the old one to the new one. Dont get it how to do it. Hope you can help me out. thx!

    Absolutely, instead of using the assembled nand, you need to create a new emunand on the new sd card, dump the first 1024 bytes of that card, then dump the entire hidden partition of the old sd card, take the first 1024 bytes you dumped from the new card and overwrite the first 1024 bytes on your dump from the old card. Write it to your new sd and it will work.

    Is there an application that can do this in an automated way?

    No actual there is no tool for that. You have to do this by yourself

    I'm on Windows, is "dumping the first 1024 bytes" of the card as simple as copying and pasting the bytes in HxD from one card to another? Or do I have to specifically dump it somehow?

    You can definitely just copy/paste if you know what you're doing.

    Cheers for the super quick response.

    Just to double check I'm getting this right, I have an image of my current 128gb SD card. So would I be right in thinking that I'd need to:

    1. Create new emunand on new 400gb SD.
    2. Copy the first 1024 bytes in HxD of the new emunand.
    3. Paste those 1024 bytes into the first 1024 bytes of the img backup of my old SD card.
    4. Use that image on my new SD card and then expand the partition?

    it'd be awesome to see this expanded so it dumped the hidden partition NAND to files, then the files were compatible with the emuNAND as files on SD (or would they be already using the dump method?)
