ROM Hack Help I can't get my private header

[babybel1000]

Hello, I bought a game to get its private header,

I have a n3dsxl and sky3ds+

I dumped the rom with braindump, but it's a .cxi file

I decrypted it with ctrtool but all I get are RomFS and ExeFS folders

How to I get a .3ds from this ? Then I will be able to get the header.

Or maybe, is there a way to directly get the header from those folders ?

Thanks

use decrypt9 and dump the header from your cardridge.
totally unessessary to dump the full cart.

Hi, thank you for your answer,
I tried Decrypt9, sadly all I get when I launch it,
is a black screen, red screen, black screen, red screen, then
it get back to the homebrew channel

If you're on 11.3, you can't use it.

use the luma chainloader and use the arm9 payload. tick patch arm9 svc patches in luma if you want to use the 3dsx version of decrypt9

There's no other way ? I just need a homebrew like braindump, but that dump .3ds not .cxi
and I'm afraid to install this arm9 thing, I could brick my 3ds.

no you can´t brick your 3ds if you don´t follow the guide. it just overwrites the ctrnand to 2.1 and then FIRM0/FIRM1, anyways you have to be on </=11.2 anyways just build your .3ds then

Thanks for your answers, I'm on 11.2.0-35E btw

I recompiled my .cxi file into .3ds

Can I get the private header from it (for safe online play) ?

Or should I get through this arm9 thing.

Personally you should follow the https:3ds.guide

https://3ds.guide/fr_FR/get-started.html its translated into french

3ds.guide and btw the arm9 processor/kernel is something different. we are are talking about the exploitation of the arm9loader which is called arm9loaderhax.

I dumped the savefile from my original retail game with JKSM and I opened it with HxD,
is my header anywhere there ?
