Haku33 is a C++ open source homebrew application that can perform a Hard Reset of the Switch, and leave it as if it had just left the box.

The aim is to clean the NAND so it can connect to Nintendo and utilize all original features, regardless of whether you plan to uninstall CFW or use emuNAND (emummc).

Note: Make sure you read the Disclaimer and understand all the risks before using it.

User guide

What it does

Haku33 eliminates critical files from the console to perform a hard reset of the switch, leaving only the essential to boot.

The affected routes are:

• System:/saves
• System:/savesMeta
• User:/*

This completely removes console logs or other information that CFW ever existed.

Disclaimer

• It is advisable to make a backup before using it, since despite being well tested, failures can occur.
• The author is not responsible of bricks, melted switch, nuclear explotions or full aniquilation.
• The premise is elimination. Can it be the lack of information that makes you get banned? So far the case has not happened.
• It is true that it is not 100% safe, but the people who have tested it have not been banned yet Reference.
• Haku33 is a simplification of this method of clean.
• If you have a clean backup of the Nand, it is better use that.
• If your console is Banned there is nothing to do.
• This will completely clean your switch, so you will lose everything.

Mariko consoles

Note: Ipatched(Mariko) are supported but used under your own risk.

Mariko consoles cannot reboot to the payload, so to load the payload Haku33 have to Overwrite some files on sd.

• Haku33 Support Mariko in part and not support clean emummc.
• if get a black screen, Press power like 3 times to make the console Wipe an boot.

Note

Keep in mind that this program will not UNBAN you, or will it make you immune to BAN. You will have a console as just out of the box, that's it. So you can go online as long as you keep the console clean of cfw.

It is recommended you always have a backup of the nand for security reasons.

A guide to installing Haku33 on the Nintendo Switch to "try" and reset to factory settings (Fixing, Modding, Building Retro Consoles and More)

Compatibility

Tested by the author on Atmosphere CFW and SXOS.

Known issues

Black screen after 17.0.0, 3 possible solutions for the problem:

• Just run atmosphere on Sysnand.
• Delete system:/saves/8000000000000120 using tegra explorer.bin and then run atmosphere to rebuild db.
• Delete system:/saves completely using tegra explorer.bin an the run atmosphere (this will make a full factory restart).

v5.7 2023/10/28

• Added an exception to avoid deleting the index file
  • Resetting this file causes a softbrick for consoles 17.0.0 or higher.
  • This is a change made by Nintendo to the way system saves are handled in 17.0.0
  • Broadly speaking, there was a list which kept track of the saves, until 17.0.0 it was not used for system saves, but after updating it is used for this and causes the console to not find importan files to boot OS, full explanation Here SciresM 17.0.0 Save File Management.
  • As well as the format of the imkvdb.arc (for the most knowledgeable) Here
• The solution comes from SciresM with Atmosphere 1.6.1 which detects the problem and
• Rebuilds the Lost data making the system boot Again.
• Although there are other possible more manual solutions (signing a file from another console and puted in) that do not involve running CFW, this is the easiest and safest of all, plus running CFW itself does not get you banned, so as long as you only run pure Atmosphere to fix the error there should be no risk of ban afterwards
