Hacking Possible to downgrade emunand?

[MassExplosion213]

Would it be possible to downgrade emunand? What if you region changed using old update files?

yeah i think if you just install the cia files on the update folder in bbm or devmenu. and select install every cia i think it should work. might be risky tho. it works for upgrades but not sure about downgrades. you found your 3ds?

Yep. And I'll test later.

I already tried to downgrade my emuNAND like that and it's not working...

Maybe with sysUpdater on emuNAND !
I read that at the end of the github : https://github.com/profi200/sysUpdater

5. Start the app and follow the instructions. Downgrade means it uninstalls the title first if the installed versions are newer.

I will test !

most people would want emunand to be as higher as possible
what are the benefits of downgrading emunand??

 

[pakrett]

Why not ? If you need to test something...

 

[MassExplosion213]

Would it work if you region change with like, say, 2.0.0 update files?

 

[pakrett]

I don't know but to region change you need to do more than just install an update pack.
Why 2.0 ?

I have a 2.0E, I can test to install it on my 9.9E emuNAND if you want.

Why 2.0 ?

Testing an exploit patched in 3.0.0. It lets you dump the OTP. And the only other thing you need is SECUREINFO_A for that region.

EDIT: The SecureInfo_A is only for region change. For info on the exploit, check 3dbrew.

 

[MassExplosion213]

And sure, try it.

 

[pakrett]

Ok, here we go !
Are you familiar with region change ?

Yea. I have a european emunand. Of course, american 3ds.

For info, I will try with cakeMode, and rxMode or reiNAND after that if it does'nt work.

Can you acces to the eur e-shop on your emuNAND ?
I try to region change to jpn and I can't access it...

No. Public donor file.

No. Public donor file.

Ahhhh ^^ public a secure info doesn't work ?

 

[MassExplosion213]

Ahhhh ^^ public a secure info doesn't work ?

Nope.

 

[pakrett]

Good to know ! Maybe we can share our secure_info between us ?

I currently backup my emunand...

Yea. Pm me yours and I'll pm you my american one when I get home.

Cool, I'll do it !
There is a downgrade fonction in sysUpdater 4.1, you just have to press Y instead of A ^^
Unfortunatly my emuNAND won't boot after that, I'll try with a 4.5 update because maybe the prblm is that the last nativ firm can't load a 2.0 emuNand...
I will also test with the 2.0 nativ-firm.bin but if it works it will be without sign patch...

Do you have the 2.0 native firm.bin?
