Now that your SD card contains the ExFATHAX image, it’s time to boot the Switch into RCM and send the initial payload.
Downloading and installing the exfathax img is a straightforward process once you understand that it’s a raw disk image meant to replace a normal SD card layout. To recap:
Remember that the biggest risks are bans and bricking. Always make a backup of your sysNAND before any flash operation. And if something goes wrong, you can always revert by formatting the SD card back to exFAT or FAT32 using the official SD Memory Card Formatter tool.
Now you have the knowledge. Use it wisely—and happy homebrewing.

What is it?
exfathax (often referred to as exfathax.mtc or the exFAT hax exploit) is a small piece of code used to exploit a vulnerability in the Nintendo Switch's handling of the exFAT file system driver.
Most "IMG" files you find online are not the exploit itself, but a pre-configured SD card backup.
Once the IMG is flashed, you insert the SD card into the Switch. This is where "exFAT Hax" actually triggers.
