Frequently Asked Questions

Should I disable WiFi?

This is an extreme that you don’t necessarily need to take, though it will basically 100% guarantee you won’t get banned (since you are basically banning yourself).

Using 90DNS (163.172.141.219 or 45.248.48.62) or enabling GDPR protections is usually enough to keep from being banned as long as you don’t care about NSP files.


What are sigpatches?

Sigpatches allow your Switch to install and run unofficial NSP files (digital titles that appear on the home menu). Note that you must use CFW to launch these applications even after installation as sigpatches are always required to do so.


Is it safe to update to the latest firmware version?

When a new firmware update is released, you should always wait for SDSetup and/or SDFilesSwitch to add support for it, or if a trusted source says it is safe. New firmware versions can also bring unwanted telemetry. Ultimately, whether or not you update is up to you.

As of writing, the latest firmware version is 6.2.0. It is currently completely safe to update as long as you are using Kosmos/SDFiles v11.5+ or a bundle from SDSetup downloaded after December 8th 2018.


What does ‘burning fuses’ mean? / Can I downgrade my Nintendo Switch?

The Switch uses a common anti-downgrade technique that utilizes microscopic (ie. cannot be replaced) fuses built into the CPU. When you turn on your Switch through regular means, the firmware performs a fuse check:

  • The firmware will first check for how many fuses are burnt
  • If there are less fuses burnt than the firmware version expects, it will burn up fuses up to as many as it expects and reboot.
  • If there are exactly enough fuses burnt as the firmware expects, it will allow the Switch to load
  • If there are too many fuses burnt, your Switch will shutdown, not allowing the firmware to boot.

The fusee-gelee exploit happens before any of these checks occur, meaning these checks can be bypassed. Hekate, ReiNX, and SX OS all block fuses from being burnt and bypass the fuse check, meaning you can keep your Switch in a downgradable state if you update your firmware manually.


How can I load .XCI cartridge backups?

Currently only SX OS is able to emulate cartridges using XCI files. SX OS is a paid custom firmware (usually $25 USD depending on the reseller) by Team Xecuter, with some drama behind it due to theft and license violation of open source code.
