Step 1: Update Atmosphere and Hekate

The first essential step is to ensure that you have the latest versions of both Atmosphere and Hekate installed on your Nintendo Switch. Checking for updates is straightforward:

  1. Visit the releases page of Atmosphere and Hekate to determine if there are newer versions available.
  2. Update both programs to their latest versions, as this significantly reduces the likelihood of encountering errors after a firmware update.

Step 2: Verify Atmosphere Files

Sometimes, firmware updates may inadvertently delete or move essential Atmosphere files, leaving them only in the EMUMMC partition. To resolve this, follow these steps:

  1. Check your SD card for all the necessary Atmosphere files. If any are missing, proceed to replace them with the appropriate versions.
  2. Ensure that all Atmosphere files are in their correct locations on the SD card.

If the error persists after completing the above steps, don’t worry; there are other solutions you can try:

Fix 1: Check Your SD Card Format Ensure that your SD card is formatted in either FAT32 or NFTS format to maintain compatibility with the Nintendo Switch.

Fix 2: Configuration Files Sometimes, crucial configuration files may be missing due to updates. Verify the authenticity of the configuration files on your console, and if any are missing, download newer updates to replace them.

Fix 3: EMUMMC Partition If your atmosphere files are only present in the EMUMMC partition, download them again and ensure they are correctly placed on the SD card.

Fix 4: Fusee Files Consider replacing the atmosphere and fusee files as mentioned earlier. Replacing fusee secondary files with the fusee primary file or the original package’s fusee files may resolve the issue.

Fix 5: Nintendo Support Team If you find the troubleshooting process challenging, don’t hesitate to contact the Nintendo support team. They can provide personalized guidance and assistance to resolve the error effectively.
