Is the list on OP post reliable for listing what firmwares are currently supported by svchax?

no, just test it, if it works (even after some failed attempts), and you can go back to the homebrew menu and start something else, then it will work fine there.

not all offsets change between firmwares, and if it can't find a matching one, it will use the offsets of an earlier one.

Using n3DS XL on 10.5.0-30U and it instantly succeeded on the first try.

Code:

svchax
Press start to exit
result : SUCCESS !!!
kernel version : 2.50.11
frames : XXX

N3DS 10.6, worked 4/5 times.

Just to get updated about this recent situation...

There already is a downgrade working from 10.5/10.6 system on New and Old3DS, right?

No hardbrick reported so far?

Thanks

Here attached are the dumps for firm 0x02300300. (9.3-9.4)

btw- Could you possibly post the source for the pagedump app? I would like to port it to 3dsx so I can get more dumps from sysnand on other firms, thanks. :^)

@aliaspider What versions of NATIVE_FIRM correlate to what kernel version? I could grab a few dumps if I had the info on that.

Now working!

thanks, and no it wouldn't work in 3dsx.

Someone with N3DS can try this demo and report me output?

"amtest:0xD8E06406

Isn't the pagedump app only grabbing something from a11 kernel memory?
If so, memchunkhax2 can already access that from a 3dsx 9.0-10.3.

I managed to Downgrade my Limited Edition Princess Peach 3DS sucessfully to 9.2.0-20E.

An Systemformat before Downgrading and it worked without Problems.

Thanks @aliaspider for your Great Work.

try just deleting the nintendo 3ds folder off your sd card, back it up first if you have anything important that's where your saves and themes and stuff are. that helped me, formatting shouldn't actually be necessary.

Not working neither. I had to format my console... But it works now

There are several hard bricks reported but all of them were user error. I.E. flashing the o3DS files on n3DS and things of that nature.

The worst brick you should get is a soft brick, though through user error you could get a hard brick. There is always that slim chance. Make sure you backup your NAND before downgrading.

if we had a hardmod i think we would have already downgraded XD

You can back up your NAND without a hard mod...
