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!​

Restore it using Hekate if that is where you got it.

i lost file from incognito, this file i got from atm autobackup

Does it include your serial, or was it made after Incognito was installed? If it's zeroed out, it's from after Incognito was installed.

it’s included serial, but only 32kb

Is there a way to restore a prodinfo.bin file made by the original Incognito using this? I just tried but I'm not sure what the filename should be, and it doesn't seem to work..

edit: nvm I was able to restore it using this https://gbatemp.net/threads/a-custo...phere-that-allows-writing-to-prodinfo.541609/ (had posted a link to the wrong thread before lol)

 

[fluffymadness]

just out of curiosity, can I assume if I use this payload, that the logs that were collected before (probably containing my prodinfo and other stuff) are not transmitted to nintendo when going online since nintendos server blocks connections without correct prodinfo, or will telemetry be always sent and just the connection to the eshop will be blocked?
Otherwise the "better-safe-then-sorry-way" would be to start with a clean nand and then using icognito rcm to ensure that there aren't any logs containing my prodinfo to begin with.

edit: is there any way to manually clear
0x80000000000000D1 erpt save:/ ?
this is where all logs should be stored according to atmosphere wiki

(I have a backup of a clean nand but it feels too much of a hassle to restore and start anew)

I got the "Validate...error" too, and didn't show any detail message. Any helps?

Getting Validate error

If you have a rawnand backup from before you installed Incognito, it also contains your prodinfo and can be restored.

How exactly can this be done?

 

[Adran_Marit]

How exactly can this be done?

I havent done it but it should be

1) mount rawnand with hacdiskmount
2) input biskeys for prodinfo if required
3) dump prodinfo.bin
4) restore with incognito

note try at your own risk as I can't confirm that method at present.

 

[Muxi]

@Adran_Marit Thanks for the advice. It worked! But unfortunately not with the desired effect. The prodinfo from the user's nand backup had also already been set to Incognito.

Does this work with 9.2.0?

Edit: Found the answer to my question on Page 7. The fork located here states it works on 9.2.0 https://github.com/borntohonk/Incognito_RCM/releases

I currently only have Sysnand on 9.2.0 and contemplating setting up EmuMMC on 9.2.0, then using this tool on EmuMMC only. Or do I need to use ChoiDuJourNX to downgrade EmuMMC to 9.1.0, then run this tool, then upgrade to 9.2.0?

Ah, I hope it gets updated soon. I am just finishing my emunand install and the last step was to install incognito rcm.

Now I will be waiting I guess.

I believe this version has been updated for 10.0.0.

just tried the link that Lacius posted and it worked great. Using Kosmos 15.5 with firmware 10.0.0. Thank You

Will this work with 10.0.1?

Update to atmosphere 0.12.0 and blank prodinfo using exosphere.ini.

There is no need to actually modify your NAND anymore.

Is it as effective as Incognito? The changelog said they weren't sure if PRODINFO was cached elsewhere.

That's true for incognito as well.

Double-edged sword though - you’re not protected if you accidentally boot into non-RCM or delete exosphere.ini.
