Changing SD cards

The goal of this page is to transfer the contents from one SD card to another one. The method to do this will differ, depending on whether you're using a partition based emuMMC on your SD card or not.

We will be using hekate to both backup and restore the emuMMC, so make sure that you have its latest files on your SD card already.

Instructions

You should first check whether you have a file or partition based emuMMC:

1. Inject the hekate payload.
2. Tap on emuMMC.
3. Under emuMMC Info & Selection, check the text next to Type.
   • If you have one it should be either SD Raw Partition or SD File.

If you are using a file based emummc or are using no emummc at all:

1. Remove your SD card.
2. Insert your old SD card into your computer.
3. Copy the contents of your SD card somewhere to your PC.
4. Eject the SD card and insert your new one.
5. Format your new SD card to FAT32 if it isn’t already.
   • To do this, use guiformat for example (Windows).
6. Copy the files from your PC to your new SD card and you’re done.

If you are using a partition based emummc:

1. Inject the hekate payload.
2. In the main menu, tap on Tools, then Backup eMMC and set SD emuMMC Raw Partition at the bottom of your screen to ON.
3. Backup both SD emuMMC BOOT0 & BOOT1 and SD emuMMC RAW GPP (Note: raw gpp may take a while).
4. Once both are done, go back to the main menu, remove your SD card and insert it into your PC.
5. If Windows asks you to format a drive, discard it and select the drive with your SD contents.
6. Copy the contents of your SD card somewhere to your PC.
7. Follow only this page to partition the new SD card for an emuMMC setup.
8. After it’s done, exit and insert your new SD card into your PC.
9. Copy the contents of your old SD card to your new one.
10. Navigate to /backup/<some characters>/ on your SD card and move BOOT0, BOOT1 and the rawnand.bin.xx files to the restore folder.
11. Eject the SD card and insert it into your switch.
12. Inject the hekate payload once again.
13. Tap on Tools, Restore eMMC, set SD emuMMC Raw Partition at the bottom of your screen to ON.
14. Restore the backup by tapping on both SD emuMMC BOOT0 & BOOT1 and SD emuMMC RAW GPP (Note: raw gpp may take a while).
    • It is very important that for both of these the SD emuMMC Raw Partition option is enabled, otherwise you will be altering your sysMMC which is not what you want.
15. Your emuMMC is now restored on the new SD card and you should be able to launch it with fusee.bin in your TegraRcmGUI or payload launcher.
