​

The ReSwitched Hacking Team have done it again. motezazer, ktemkin and SciresM have achieved code execution on 4.1.0, the latest version at the time of writing this, via deja vu at TrustZone level. This means devices on 4.1.0 and below will be able to gain access to the whole system. SciresM strongly advises to not update in the future.

After less than a year, the Switch hacking team has moved extremely fast and now have got full access on the latest version. The progress being made is incredible, and in comparison, the 3DS took around 2 years to get ARM9 access. The scene is looking very promising so far and we are very lucky to have such talented people working on the Switch.

So me having a Switch on 8.0.0 means im still fucked right? My switch is on partially patched (XAW1011) and it automatically updated to 8.0.0 without my knowing (That or my gf did it by accident)

Will this work on my unit?

Assuming you can't push payloads on your switch in RCM, then yes unfortunately you're boned if you wanted to run CFW. 8.0.0 patched the last known TZ vulnerability.

Unless a new vulnerability is found (could be a long time/never) the highest fw an ipatched unit will be able to run CFW is going to be 7.0.1.

Partially patched isn't a thing, I guess your serial is in the range where some are patched and some aren't, so you need to find out if yours is or not by putting it in RCM mode and sending a payload.

These types of promises have gone on and on. Don't count on it.

Need I say more

Huh? All the exploits necessary for trustzone hax on 4.x (FG patched systems included) have already been public for over a month...

Edit: And all of them are now publicly implemented!

You can't do anything rn with a patched console.

@Massive20 The exploits necessary to do shit on FG patched systems are public

Currently on 8.0 but my original fuses from 4.0.X are not burned, but lost my backup 4.0.X (6.2 is my earliest backup available). Anyway to downgrade without burning fuses and without backup? Just install old Firmware file with Choidujour? Never done that before, I just wanna know if there are major risks in downgrading. Or wait for 6.2+ support for warmboot?

Rebuild NAND for 4.0.X? If you don't need clean 4.0.X NAND you can also simply downgrade with ChoiDujourNX to 4.0.X.

Ah thanks - any reports that downgrading with ChoidujourNX bricks consoles? Or is it (mostly) safe since I have backups? Never had a clean NAND so I don't care

if you don’t use the factory reset option in ChoiNX when downgrading you’ll likely get a fatal when you start the system

I am very new to the seen and in desperate need of help please help me by telling me where to look for these exploits I (mean link) to hack my ipatched unit I am from India and unable to find help anywhere else please

--------------------- MERGED ---------------------------

I am on 4.1 firmware

Just keep waiting a bit longer, they will be posted on this forum when they're ready.

Thank you for reply bud doing that now as you have said thanks again

Many bits longer...........

Feel free to write your own implementation if it's taking too long.

Is there something wrong with the truth? He was baiting him into believing its gonna happen fast and he really doesn't know when.

There's currently public implementations of every single exploit in Deja Vu for firmwares <=4.1.0 . You can stop hating now

 

[hippy dave]

As above, nothing's holding up implementation for 4.1, so every reason to believe it will be available soon. Higher firmwares not so much.

I remember someone said we can boot any CFW without care about furse count because ignoring count feature of hakate or something similar. So can we downgrade to 4.0 and take advanced of Trust Zone vulnerability without care about burning furses?

If you can boot the console via Hekate and subsequently CFW, what would be the point of booting Deja Vu?
