Hacker SciresM states he’s received reports of Nintendo Switch being sold in retail right now, that are patched against the fusée gelée exploits.
The developer assumes the vulnerabilities have been mitigated at the factory level through ipatches. This is a patching method we knew Nintendo could activate to counter the hardware hack, per opposition to a full hardware revision, which we also know is coming. (The hardware revision is nicknamed Mariko, and, as Switch hacker ktemkinpoints out, these units are probably not it, since they ship with firmware 4.1.0, while support for Mariko was introduced in 5.0.0)
Obviously, existing Nintendo Switch devices on the market are not impacted by these patches, which need to be done in factory. In other words, if your console is hacked and running fusée gelée, this changes nothing for you.
Furthermore, these new units appear to ship with firmware 4.1.0, a firmware that is still vulnerable to SciresM’s very own Trustzone exploit: déjà vu. This means those would still in theory be able to run a CFW such as Atmosphere. So if you end up with one of these “patched” units, don’t update past 4.1.0.
Bad News: Reports of new Switches in the wild not being vuln to f-g… probably updated ipatches. Good news: they’re coming with 4.1.0 for now, which is vuln to deja vu.
Friendly reminder: if you want a hacked switch, don’t update. The lower the better. This is still very true.
There’s at the moment no way to know, when you buy a Nintendo Switch, if it comes with these new protections or not. Your best bet if you still want to join the fun this late in the game, is to leverage the return policy of a retailer you trust (it can be your local store). Try to buy from them, and if the console is patched, return it. Amazon have a great return policy and usually have the switch on stock, but they might also be the first ones to get the patched models..
