incognito
Wipes personal information from your Nintendo Switch by removing it from prodinfo.

purpose
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.

disclaimer
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.

I did this on my EmuNAND… do we know if EmuNAND sends reports to Nintendo anyway?

Yes, it would

Yes, it would

just posted an update, it allows the importing of prodinfo files. in theory, if you imported a prodinfo from an unbanned console, it can unban a banned console.

EDIT: Sec

I restored a prodinfo file from a unbanned switch, and I can confirm it doesn't work

Did it boot? Or just blackscreen?

Same, get an error code2123-0011 When I try to go online. Boots fine though.

I'm pretty sure it just says "Online services have been restricted from this console"

this is huge because now we know Nintendo bans more than just the CERT from a console... probably the MAC and the Friend Code?

This also confirms that:

This software is useless if you are avoiding ban. Nintendo bans more that just prodinfo.

So just to be sure, the prodinfo contains the cert and they are not two separate things?

To run CFW without detection.
You supposed to keep CFW emunand offline, run OFW sysnand online.

Makes sense. Will do that.

Instead of replacing it with junk data, you should make an algorithm to replace the PRODINFO with a heavily modified version of the user's actual PRODINFO. This way, if the user looses his backup, they can just use the fake PRODINFO they have and reverse the algorithm to retrieve the original.

Dont want to do that, because its open source, and I do not want malicious applications reading the prodinfo. If I did that, malicious apps could reverse it unless the user was prompted for a password to encrypt it with... better to just zero it out and give them a backup.

 

[blawar]

published 1.2, added ability to verify prodinfo hashes on nand, and fixed setting the cert hash.

yes if anyone has the same edits its also shit becauce of bans.

The main reason for emunand is so you can run the latest fw while keeping your systems nand on old fw for best chance at cold boot cfw in future

--------------------- MERGED ---------------------------

anyway what are people experience with this app and testing if they can play and retain online?

 

[Darth Meteos]

I'd be careful, guys. I decided to give it a go with Kosmos, and now FTP functions won't work, the moment I connect with Filezilla, the Switch crashes. I had to restore NAND, keep away!

Related to CAL0 and Atmosphere:

Functionality was added implementing basic protections for NAND from userland homebrew:

• BOOT0 now has write protection for the BCT public key and keyblob regions.
  • The ns sysmodule is no longer allowed to write the BCT public keys; all other processes can.
    • This should prevent system updates from removing AutoRCM.
  • No processes should be allowed to write to the keyblob region.
• By default, BIS partitions other than BOOT0 are now read-only, and CAL0 is neither readable nor writable.
  • Adding a bis_write flag for a title will allow it to write to BIS.
  • Adding a cal_read flag for a title will allow it to read CAL0.
• An automatic backup is now made of CAL0 on boot.
  • fs.mitm maintains a file handle to this backup, so userland software cannot read it.
• To facilitate this, fs.mitm now mitms all sessions for non-system modules; content overriding has been made separate from service interception.

So both cal_read and bis_write might be needed to get it to work. I'm not sure what id I needed for the folder to put the files in, otherwise I would of tried.

I couldn’t get it to work even with the flags set.

Also you can read the flags.md if you want to learn more about them. It’s found on the atmosphere github in the docs folder.
