KitNX

An all-in-one bare-metal maintenance and recovery payload for Nintendo Switch.

KitNX combines commonly needed maintenance and recovery tools in one guided interface, avoiding the extra step of opening TegraExplorer and selecting a script.

Features

Network Tools

• Block Nintendo connectivity on sysMMC.
• Allow Nintendo connectivity on sysMMC.
• Display the current network and compatibility configuration.

Compatibility Tools

• Apply the bundled Tinfoil-compatible Atmosphere package3.
• Back up and restore the original package3 and boot logos.

Maintenance and Recovery

• Remove the installed qlaunch theme override at atmosphere/contents/0100000000001000.
• Repair the downgrade state on SysMMC, emuMMC, or both by deriving BIS keys and removing SYSTEM/save/8000000000000073.

Safety

KitNX separates SD-card maintenance from NAND operations:

• Network, compatibility, and theme tools modify files on the SD card.
• Downgrade recovery mounts the encrypted NAND SYSTEM partition and deletes one exact save file.
• Destructive operations require an explicit VOL+ confirmation.
• The downgrade menu disables emuMMC targets when no emuMMC configuration is detected.

Keep NAND and SD-card backups. Allowing sysMMC network access does not remove ban risk.

Installation

1. Copy KitNX.bin to bootloader/payloads/ on the SD card.
2. Launch Hekate and open Payloads.
3. Select KitNX.bin.
4. Navigate with Volume Up / Volume Down and confirm with Power.

Compatibility Data

Tinfoil compatibility files are stored under config/kitnx/tce/. Existing backups under config/netman/tce/backup/ remain available as a restore fallback.

Building from Source

Set up devkitPro/devkitARM, then run:

make

The build creates the KitNX payload and release ZIP under output/. The ZIP includes the payload and the bundled package3 under config/kitnx/tce/.
