Incognito_RCM
=
Incognito_RCM is a bare metal Nintendo Switch payload that derives encryption keys for de- and encrypting PRODINFO partition (sysnand and emummc) and wiping personal information from your Nintendo Switch as to go online while worrying slightly less about a ban.
It has a builtin backup and restore functionality.
It is heavily based on [Lockpick_RCM](https://github.com/shchmue/Lockpick_RCM) and takes inspiration from [incognito](https://github.com/blawar/incognito).
Massive Thanks to CTCaer, shchmue and blawar!
This project is in early stage, so have a nand backup!! There is not much of error handling going on.

Usage

@ -15,7 +16,16 @@ Usage
* Choose either Incognito (sysNAND) or Incognito (emuMMC) to wipe personal information
* If you ever want to revert, choose restore menu points
Keep in mind that backups will be overwritten, so don't backup after applying Incognito!
