Hacking How to downgrade Nintendo Switch firmware 6.2.0?

[larrypretty]

Is there any possibility to downgrade the V6.2.0 to v6.1.0 or lower ones and how? I just made this mistake, stupied......

Use ChoiDuJour (not ChoiDuJourNX)
Or better : restore your nand backup

It should work.

(You'll have to boot through RCM)

Let me bet... you dont use ChoiDuJour or Nand?

Of course he doesnt. He probably (like the rest of people who will come crying here) updated and now trying to find a ''secret hack'' to downgrade because he foolishly updated despite people literally screaming out every single update NOT TO FREAKING UPDATE before you know whats going on.

I never intendo to do this, the system udpate pop out when I'm playing a game, then I just click on it, and regret for my whole life...

Yes, I don't, so that means I have no way to downgrade, yes?

You can't downgrade if you don't have a NAND Backup.
You're out of luck.
Even with a NAND Backup, you won't be able to boot into it cuz a fuse were burned during the update

ftfy.

For what it's worth, after a downgrade with burnt fuses, you can still boot into your system, you just need to use a CFW bootloader (like hekate) that ignores the fuse count.

No

 

[Rushhour77]

No

Then answer is no afaik

 

[jakkal]

Why there always someone who does this

 

[johnboyjr]

do you lose save games and installed games if you restore your nand

 

[jakkal]

do you lose save games and installed games if you restore your nand

Games are saved to the nand
So hopefully you can put 2 and 2 together

 

[arianadark]

do you lose save games and installed games if you restore your nand

yes

Don't worry about it too much. The new encryption keys will get released, SciresM is already working on it. There's just no time frame and it might not be soon.

I downgraded from 6 to 5.1 without any nand backup, using only choix du jour and the update 5.1 files.

Why would the nand backup up needed this time ?

 

[sj33]

Because you cannot boot into CFW at all when running 6.2.0

 

[koyuki38]

Wait, do you mean it's possible to downgrade by restoring nand backup ?
