​

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.

you cannot be 100% sure with that
only 99%...

The guy developing the cfw said 3.0.1 and 4.1 are equal so that's pretty much 100%.

4.1 is getting everything 3.0.1 is getting, there might still be undiscovered exploits but we'll get coldboot which is all that matters really.

We've heard from primary sources that 3.0.1-4.1.0 will get access to CFW at the same time. It was recommended that users on 3.0.1+ update to 4.1.0 while they could if they wanted temporary access to the eShop and online play.

So, since Azure Striker Gunvolt has 3.0.1 on the cart and if my Switch firmware is too low. I can just go to Gamestop, buy a used copy of Azure Striker Gunvolt, pop it in my Switch, update, then return it?

If you are on 3.0.0 or lower, you should stay there. Do not update to 3.0.1 or higher.

3.0.0 and lower will get CFW before 3.0.1 and higher.

 

[loler55]

yes

yes

No don't do that, it'll add to wait time

A new Flaw in 4.x or does this one exist in all lower ones?

Probably. But note that the flaw used in 4.X could have been a new flaw made by nintendo after patching something else in the firmware. so it might exist in older firms and may not.

3.0.0 and lower will get CFW before 3.0.1 and higher.

If you are on < 3.0.1 then you can boot your switch and then use a software exploit to load CFW. If you are on >3.0.0 then you need to use fusee gelee to load CFW from recovery mode using a tethered exploit (if the >3.0.0 kernel exploits get leaked then you won't need to do that either).

AFAICT everyone gets CFW at the same time.

I'm on 3.0.1, is exploit really suppose to come at the same time as 4.1 ?
4.1 would let me upgrade to 5.1 without burning efuses and with a working cart reader... decisions, decisions.

Nay, I think 4.1 will allow you to use Emunand, that will let you run an updated Emunand instead.

 

[NoNAND]

Damn my switch is in 5.1.0

 

[Azel]

Nay, I think 4.1 will allow you to use Emunand, that will let you run an updated Emunand instead.

I will use emunand when it's out but for the time being, i meant this https://gbatemp.net/threads/how-to-...nofficially-without-burning-any-fuses.507461/.

Only 4.x or above lets you keep a working cart reader. then I could have 5.1 and reflash 4.1 when atmosphère with emunand is released.

Anyone knows how it’s going with Deja Vu, is there any progress made lately?
Trying to stay tuned with all comments in every thread made, but it seems easy to miss info =)

 

[leda]

Is there any progress released since it was announced in February?

 

[mariogamer]

Just to say: everyone will get the cfw at the same time. You'll just use the rcm exploit.

Deja vu probably won't be released soon to keep it for mariko.

 

[Xenon Hacks]

and here I am on 2.3.0 waiting on that Emunand support
