alt Hacker Newsmy nintendo switch is "rootable" by shorting two pins in the controller interface, with a previously set up SD card inserted with the homebrew bootloader.
My PS3 and PS4 were both jailbroken/rooted. I don't remember the ps3 routine, but the PS4 was loading the "system -> help" page while connected to a ESP32 wifi AP running a simple web server that replied to requests with the jailbreak for PS4.
I give it about a year, especially if nintendo has to change the specs or otherwise tampers with customer expectations. there's bound to be some way to reload firmware on a "dead" device without pulling chips, and that's all it takes.
The shorting two pins is a heavy oversimplification of what happened.
The two pins were installed by design from Nintendo to activate the Tegra RCM mode. RCM mode meanwhile has a USB buffer overflow which is the real bug.
In modern NVIDIA chips, this RCM mode no longer exists. The new recovery modes meanwhile are running across multiple physically separate CPUs verifying each other (glitch one, the other notices), all running formally verified firmware written in SPARK (the thing you use for nuclear reactors and avionics).
As for the OS itself, according to a maintainer who rewrote the kernel twice for open source, it has zero bugs. None. The microkernel is tiny, has no drivers, and almost no attack surface. This is born out by WebKit exploits being a dime a dozen on Switch, but all of them are useless.
