One of the most significant risks of jailbreaking a Nintendo Switch is the possibility of rendering your console inoperable or “bricked.” A bricked console becomes entirely non-functional, leaving you with a device that essentially becomes an expensive paperweight. You can also think of it as tuition on a lesson of what not to do with your next one.
This can occur when you incorrectly install custom firmware or make unauthorized system-level modifications that inflict irreversible damage on the console’s hardware or software. If you’ve soft-bricked the console, you may be able to restore the original software and start anew if you mess something up, but in many cases, there’s little hope of restoring functionality to a fully bricked console.
And if you’ve ventured beyond the hardware and software boundaries set by Nintendo, you can be assured that your warranty is no longer valid. You won’t even be able to pay Nintendo to fix it. If your console is rendered unusable, purchasing a new Switch console may be the only viable solution.
