EDIT: The emuNAND Tool has been updated and now works again!

Since right now the emuNAND Tool doesn't work, I've come up with a workaround:

Programs you will need:

• USB Image Tool
• EaseUS Partition Master

Both these programs are free.

PLEASE NOTE: Doing the following method will make a 1:1 copy of the source SD card and put it on the target SD card. It will transfer everything, not just emuNAND.

How to:

1. Plug the source SD card into your PC, this is the card that you want to transfer emuNAND from.
2. Run USB Image Tool
3. Click on the SD card and then "Backup"
4. Remove the source SD Card and replace it with the target SD Card.
5. Click on the new SD card, locate the backup image and then "Restore"
6. Run EaseUS Partition Master and click on "EaseUS Partition Master Free"
7. Right click on the SD card's partition with data on it, it should be in between two Unallocated partitions and choose "Resize/Move Partition"
8. Click on the MIDDLE PARTITION, the one that has the data on it and expand it TO THE RIGHT (VERY IMPORTANT)
9. Click OK
10. Click Apply on the top left, then OK
11. Done!

Important Information:
Currently with Gateway 3.1.0 there's a (visual?)bug with higher capacity microSD cards. When running emuNAND it doesn't show the "GW3D" in settings, before the version number telling you if you're in emuNAND or not, because of this its very risky to update emuNAND.
With my guide you can use a 4gb microSD card (where the visual bug doesn't happen) to format emuNAND, update to the latest firmware and transfer it onto a higher capacity microSD card.

Don't panic! - When the transfer is complete and you run the updated emuNAND on your new 3ds it still wont show the "GW3D" prefix before the version number. It'll just say 9.5.0-22E or something along those lines.

Any questions, feel free to ask

When I expand it to the right like the tutorial. It only recognized my 64GB sd card down to 16GB. What happened!?

 

[Devilhunter142]

Wanted to say thanks for this tutorial, it worked perfectly. One thing I screwed up though was when you're expanding the partition on step #8, I dragged the actual partition to the right and basically just moved it over instead of dragging the right edge of the bubble to actually increase the size. Dumb I know but yeah, I started over and realized what I did and worked great.

Went from a 32gb mSD to a Sony 64gb mSDXC. The restore of the image changed the file system to FAT32 so it works just fine.

Can you show me the step by step to drag over? I did exactly like the tutorial but it seem it just copied everything from the old SD Card, now my 64GB is only recognize as 16GB. What happened? And the other 44GB Unallocated, what do I do to increase the size?

Will this work with the decript9 luma cfw 11.2?

Will this work with the decript9 luma cfw 11.2?

If the SD card you're transferring to is bigger, you can just copy everything from the old one to the new one and then resize the partition. If it's smaller, shrink it first and then copy.

Will this work with 11.3 CFW. I would like to transfer all my data from my 3ds 2gb sd card to a 32gb sd card without it erasing anything.

Im getting this error everytime I try to apply the changes.

Try doing the same thing in diskpart instead of the EaseUS Partition thing.

 

[Cortexfou]

I want to transfert my emunand from my 32Go to my 16Go. How can I do that ? With this method, they say "the image fileis too large for the selected USB device!"

It's probably easiest to just dd everything from the old SD to the new one, then format the partition in diskpart and copy all the files over.
Use this port of dd if you're on Windows: http://www.chrysocome.net/dd

This method worked with decript9 luma
Transfered data from 8gb to 32gb card
Thanks for the guide!

Hi, this worked for me, (Thanks!), but for some reason, my 64gb sd is showing up as 8gb, the same as my old SD. I desperately need space, and im trying to format now. Did I slide in the partition tool too far? I did it all the way...

Did you extend the partition with the filesystem all the way to the right?

Yeah I pushed it to the right completely

4. Remove the source SD Card and replace it with the target SD Card.
5. Click on the new SD card, locate the backup image and then "Restore"

If my target SD card is formatted in NTFS, but the original source card was in FAT32, would the backup image change the filesystem when clicking "Restore"? Or would I have to format the target SD card to FAT32 in advance before restoring it with the backup of my original card?

Just in case, I used MiniTool Partition Wizard Free Edition 10.2 to preformat it to FAT32 with 32 kb size clusters before restoring the backup image.

Try using Unlocker to check what's using the drive and unlocking it so you can write to it.

omg i feel so dumb rn all i had to do was unlock it so i could write on it, thx for reminding me about that!

edit: I have also try with M-Magic Partition Resizer, which seems to be able to resize FAT32 partitions and got the error "No partition table found for this device".

Any help?

Try doing the same thing in diskpart instead of the EaseUS Partition thing.

Hi @member , I have try your method and would like to ask if you know why I´m getting and error with diskpart "the volume cannot be extended because the file system does not support.

My card is FAT32, could it be that windows does nto let you extend units rather than NTFS ones?
