Safety Precautions (Caffeine)¶
You are now able to run Hekate on your Nintendo Switch to launch the Atmosphere (Kosmos) custom firmware. These next steps will make sure your being as careful as possible in regards to keeping your Switch from bricking and getting banned. These steps are optional but highly recommended
If something goes wrong or you need help, check troubleshooting.
Step 1: Backing up your NAND and BIS keys¶
By backing up your NAND (the Switch’s internal memory), you will later be able to restore it in the event that anything goes wrong, essentially rewinding it back to a previous state. BIS keys are also good to backup so you can reinstall any firmware version manually should your NAND backup become corrupted or lost.
THIS STEP IS NOT OPTIONAL, ESPECIALLY FOR IPATCHED UNITS.
Enter Hekate from PegaScape if you have not done so already.
In Hekate, select ‘Tools > Backup eMMC > eMMC BOOT0 & BOOT1’
Use Volume +/- to change menu selection and Power to select an option.
When finished, remove your SD card (you don’t need to shutdown Hekate), insert it into your PC, and copy the ‘backup’ folder to a safe location on your PC. Afterwards, delete the ‘backup’ folder on your SD card.
Insert your SD card back into your Switch
In Hekate, select ‘eMMC RAW GPP’
If your SD card has less than ~32GB free space, Hekate will provide additional instructions every few minutes about pulling files off of your SD card so it can continue.
If you weren’t required to copy files during the backup process, once again copy the ‘backup’ folder off of your SD card and put it in a safe location on your PC. Delete the ‘backup’ folder on your SD card.
Close the Backup menu and go back to the Home tab.
Tap Payloads > Lockpick_RCM.bin (if you do not have this payload, you can obtain it from GitHub and place it at sd:/bootloader/payloads/lockpick_RCM.bin ).
Press the power button to shutdown.
Insert your SD card into your PC.
Copy the /switch/prod.keys file to a safe location.
It is highly recommended that you store these backups and keys in multiple locations (ex. cloud storage, external harddrive, etc) as they may be critical to restoring your Switch if anything goes wrong in the future.
Step 2: (EU Only) Enabling GDPR Protections¶
Users with EU Nintendo Network accounts have the option of enabling GDPR protections in their account settings. Doing so has been confirmed to disable lots of telemetry that can get you banned. This setting will not appear if your account is not from the EU.
