Error 3: "NCA Signature Verification Failed." Step 1: On your PC, create a folder
If you are using a standard Nintendo Switch, updates are handled directly through the console's interface while connected to the internet.
Step 1: On your PC, create a folder on your SD card called NSP (or Install).
Step 2: Copy the Super Mario Odyssey [Base].nsp and Super Mario Odyssey [Update v1.3.0].nsp into that folder.
Step 3: Insert the SD card back into your Switch and boot into CFW.
Step 4: Open the Homebrew Launcher and run Goldleaf or DBI.
Step 5: Navigate to "Install Titles from SD Card."
Step 6: Locate the Base NSP. Install it to the SD card (or NAND if you prefer).
Step 7: Locate the Update NSP. Install it.
Step 8: The installer will ask if you want to install as "Update." Select Yes.
Note: This method is slower than USB and uses double the temporary space on your SD card, but it is foolproof.
