Article summary

The Nintendo Switch uses irreversible hardware fuses to prevent firmware downgrades, making it impossible to revert to a previous state once a fuse is blown. This is done to prevent end users from modifying their devices and to prevent piracy. The fuses are part of the Nvidia Tegra X1 SoC and are programmatically blown by the device's boot loader. The use of these fuses is not unique to the Switch, with other devices such as the Xbox 360 also employing similar techniques.
