Black screen at boot?

[ghost]

I have a Japanese N3DS (Not LL) with sysNAND 9.1 and no emuNAND installed. Will I need to install emuNAND for this to work? Im using the latest version.

[aroth-khashar]

Yes, The default boot behavior is to attempt to launch emunand.

How do I set it to sysNAND?

[aroth-khashar]

I believe you can hold B when you press Start at the splash screen to load into sysnand.

[aroth-khashar]

Keep in mind that this functionality is missing if you are using a modified build that autoboots, and I think @Reisyukaku is planning to remove it in the next commit.

Thanks.

@aroth-khashar Whenever I start the ReiNand.dat or ReiNand.3dsx I get a black screen with nothing prompting me to press start. What am I doing wrong? Heres my filesystem (minus alot of unrelated stuff)

I have not been successful getting the .3dsx file to boot. How are you launching the dat file?

[aroth-khashar]

For reference, I use ctrbootmanager to load the dat file directly, with an offset of 0x12000

When I try using ctrbootmanager it says boot.cfg not detected and that its making a new one then freezes. Even though I have a boot.cfg already

[aroth-khashar]

hmm, where is your boot.cfg located? Also can you upload it so I can check the contents?

[aroth-khashar]

Try placing this file on the root of your SD card and renaming it to boot.cfg, then booting with ctrbootmanager.

I seem to have got it working. But for some weird reason when I went into emuNAND with reiNAND then used browserhax to goto FBI, CIAs still say invalid signature.

[aroth-khashar]

What version is your emunand on?

You cannot use the .3dsx version of FBI on 9.3+, period. Doesn't matter if you are on emunand or have signature checks disabled. On 9.3+ *hax does not provide the level of permissions needed to install cias (signed or unsigned, doesn't matter) at those firmwares it only has arm11 userland access.

[ghost]

Yeah I realized I was an idiot and forgot to install a CIA manager before updating -_- Now I might have to reinstall emuNAND

[ghost]

Oh and @aroth-khashar I think there's a (experimental) FBI build that has memchunkhax which might fix my problem
