Hacking Installing other-model system-titles

[Sunho]

Sorry for my bad english.
I found that Installing other-model system-titles is possible on 3dbrew.
(https://www.3dbrew.org/wiki/Titles#Installing_other-model_system-titles)
I think it means system titles of O3DS can be installed on N3DS and it can be a only way to downgrade Korean N3DS to arm9 exploit working version. (Initial version of KOR N3DS is 9.6)
Does anyone has any idea how to do this?

P.S. neobrain, can you help me?

Please do not try to downgrade by using o3ds firmware files on a n3ds, it's been done before (on accident by other users) and is a guaranteed brick.
You are misreading what that section is saying. I don't fully understand it, but I do know for certain it does not mean you can install o3ds system titles on n3ds, or at least not all of them.

Theoretically it should be possible, but it's a little more involved than that. Something similar is done for getting OTP. You'll lose the n3DS-specific features by doing so though.
There's one thing preventing it from being possible, and that is the fact that you need direct NAND access to patch the header as well as reencrypt the NAND with o3DS keys. If this isn't done, the o3DS firm cannot read the NAND = brick. Direct NAND access as well as decrypting / encrypting the NAND requires ARM9 kernel access.
It's safer to region change the console anyway. And if you still want the console to be in korean, you can make an emuNAND but region change the sysNAND only. Nevermind, this won't work because you need to be on 9.2 or lower to replace the SecureInfo_A file.
I guess there's no way you can hack that 3DS.

You shouldn"t go trought all of that only for have Korean 9.2, you will be better region changing the EmuNand if you are using it instead.
It"s possible for sure but I don"t think you should since it isn"t very safe.

It's a catch-22.
Without having 9.2 or lower in the first place, none of it is possible. But if he had 9.2 or lower already, it wouldn't be necessary.

Getting OTP, we have to reencrypt NAND partition. I think that reason is O3DS NATIVE_FIRM.
I guess N3DS NATIVE_FIRM with N3DS system module and O3DS system titles could be possible.
I'm not sure but I believe that I can try it with other N3DS which is region changed.
