I want to unlink my EmuNAND from SysNAND. So, I removed the MicroSD card from my New 3DS XL, Powered on the System, went to Settings (in SysNAND), Went to 'Format System Memory', and pushed the red 'Format' button. However, after a few seconds, I get Error: 005-5602. And it fails to format the System. I am connected to the internet. What causes this problem and how do I fix this?
