Incognito_RCM

since Incognito by blawar doesn't work on vanilla atmosphere, I made a payload to use with hekate (or any other payload injector) with the same functionality.
Incognito_RCM wipes personal information from your Nintendo Switch by removing it from prodinfo.

Functionality:​

• wipe personal information on sysnand/emunand
• backup prodinfo from sysnand/emunand
• restore prodinfo to sysnand/emunand

Since NAND memory is encrypted, this is based on shchmue's Lockpick_RCM to first get the neccessary encryption keys.
You can apply Incognito_RCM directly after installing atmosphere or any time after and it has the advantage that you don't need to set 90DNS after an internet connection and possibly communication with nintendo servers is already established. (You can apply 90DNS anyway)

This has only been tested by me on firmware 8.1.0, so please test it and report back.
Since it has only been tested by me, keep a hekate nand backup ready to be safe.

Disclaimer:
This is early stage and there is no guarantee that everything works as expected! Please have a hekate NAND backup ready!​

thank you for testing!


Thanks, will surely apply for adding this to the homebrew app store, but first want to get some testing!
@feral 's report is the only one so far...

just to add, i backed up my sys prod info perfectly with this, i also ran it on my emummc and restored a 'wiped' prod info and the restore worked perfectly.
10/10 from me buddy!

life pro tip: Never assume, you make an as out of you and me

Thanks for the totally original advice. You've made me a better man.

 

[jimzrt]

so... new release
https://github.com/jimzrt/Incognito_RCM/releases/tag/v0.3.0

• more error handling
• backup validation when reading and writing
• retry up to 5 times when reading and writing before aborting

I think I'm pretty much done now... There is not much to add in terms of validating. All that is left is fixing if bugs reveal themselves.
Also, no "features" that come to mind that I could add.
Of course I am open to suggestions!

there's an existing progress bar already in the codebase btw, tui.h - tui_pbar()

 

[Crusatyr]

It doesn’t nuke everything from prodinfo, and there also some console unique stuff in fuses.

The console unique fuse stuff doesn't matter since Horizon cannot read from or write to fuses.

 

[ZachyCatGames]

Yea, but they could change that if they wanted to, not that I think they would or should.

 

[shchmue]

settings services caches some or all of this stuff in a system save fwiw

oh, looks indeed nicer! adapted it.

still can't work on sx 9.0 please help us

 

[Localhorst86]

still can't work on sx 9.0 please help us

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

still can't work on sx 9.0,"No emuMMC config found" . please help us!

Calm down there, mate. If your using sx os, why don't you just use blawars nro version or sx oses built in stealth mode?

 

[anhminh]

What do I do with the .bin file?

 

[Localhorst86]

What do I do with the .bin file?

You inject it as a payload

Because I am not sure that other methods are really effective…

 

[Localhorst86]

Because I am not sure that other methods are really effective…

This is literally the same method that blawars incognito uses, but as a standalone payload.

 

[milanese]

This is literally the same method that blawars incognito uses, but as a standalone payload.

I see … Since incognito doesn't work for me, Incognito_rcm also could not be applied in sx2.9.

 

[darkxex]

Use atmosphere emummc.ini for sx os.

 

[Slim45]

can anybody confirm if this works on 9.xx?

 

[jimzrt]

can anybody confirm if this works on 9.xx?

@jimzrt this seemed to work fine on my 9.0.1 emunand. I was able to make a backup of prodinfo and Atmosphere reports a blank console serial, just like when I previously applied icognito to my 8.1.0 emunand. I didn't test the restore feature.

 

[Slim45]

cool all i wanna do is blank out my emummc and keep sysnand legit but let it connect to wifi with 90dns as well just to be extra safe so i can keep updating homebrew wirelessly

 

[xmp8851]

does it remove totally same thing compare to original incognito?

 

[jimzrt]

does it remove totally same thing compare to original incognito?

yes

Hello, I have questions :

1. If I lose my prodinfo backup, is there a way to recover it or not ?
2. Should I do something before or after update to another firmware ?
3. If I keep my switch only for hack/piracy or anything else, could be a reason to restore my prodinfo in the future ?
4. If I transfer saves between a switch that has incognito and a switch used for only (without hack), could one or both switch be banned or the transfert impossible ?
5. To install it properly, which step should I follow exactly ?

Thank for this work

1. No
2. No
3. No
4. No
5. Backup your prodinfo with Hekate, then run the app. Store it somewhere safe online.
