Wipes personal information from your Nintendo Switch by removing it from prodinfo.
a) So your switch can go online without worrying about a ban or using random dogdy DNS servers that are also likely to get you banned.
b) so malicious homebrew applications cannot steal your personal certificate.
Always have a nand backup. I am not responsible for any bricks or bans. Use at your own risk, experimental.
This application backs up your prodinfo to the SD root, you should keep this backup in a more secure location, and not leave it on the SD card where malicious applications can read it.
edit: atmosphere blocks writes to CAL0, so you must use ReiNX or SX OS to install this. Once installed, you can switch back to atmosphere.
