Hacking Can't install FBI sysnand

[Cortexfou]

Hi,
I have already a CFW on my 3ds but I want to install some GBA games on my sysnand tu play them on my emunand but, I don't know why, FBI is gone and I can't reinstall it. When I try to go to the homebrew launcher on my sysnand, I go to my emunand and when I go the the Homebrew launcher with my emunand, I can't launch Decrypt9WIP or RXtool.
Can you help me to install my .cia on my sysnand ?
Thanks

Are you running a9lh? Boot decrypt9 right form a9lh. Do you know how to use payloads?

 

[Cortexfou]

no and no. I install my CFW a long time ago. I only use Luma3ds and boot manager (and all the things to install these) and I didn't change anything

I'm not sure exactly what's going on. Are you using menuhax?

You can follow this guide to get a9lh set up https://3ds.guide/

I would recommend very carfully updating with these instructions:

https://3ds.guide/updating-a9lh

I think you'll want to inject FBI into health and safety afterwards, then install FBI, then inject health and safety back again with this guide, Section V - Injecting FBI:

https://3ds.guide/installing-arm9loaderhax

Then I would ditch emunand and use sysnand.

I think I installed menuhax when I installed boot manager or something but I don't use it. I just start my 3DS and the CFW boot.
I want to use that : https://gbatemp.net/threads/release-inject-any-app-into-health-safety-o3ds-n3ds-cfw-only.402236/, very simple but Decrypt9WIP won't launch. I have a red screen and then, back tu my emunand.

The thing is, he says he doesn't even have a9lh (I dunno how true that is).

 

[Cortexfou]

100% sure I don't have a9lh

 

[x65943]

100% sure I don't have a9lh

In that case install a9lh with https://3ds.guide/

It will set you up to inject fbi, and you will be much happier with it.

Well if he says he has luma, then he must have A9LH, I think...

OP, power down the 3DS, then hold select and keep it press, whilst simultaneously switching on. What do you see?

That's not true. You can run Luma with menuhax. But I approve of your steps to see if he does indeed have a9lh.

 

[fenderjaguar]

That's not true. You can run Luma with menuhax.

OK, I didn't know that, thanks

 

[Cortexfou]

When I hold select, it's boot manager with all the stuff like luma, homebrew, reinand, ect. Like I said, I used menuhax to install boot manager and RXtool (updated to luma somes times ago). It was like in 2015 and I touched nothing since then (exept the update RXtool to luma)

 

[einhuman197]

Emunand doesn't allow you to run arm9 software. To boot to cfw sysnand, hold L when you load Luma. I highly recommend 3ds.guide to install arm9loaderhax.

I think I'll try to install A9LH... Can I play GBA games with this ?

Yes.

 

[Cortexfou]

I just need to install the CIA and that's it with A9LH ?
Also, I put my micro SD in my PC and I think there are a lot of garbage on it. If I take a screenshot (after installing A9LH) of the folders, can you tell me what files are useless or not ?

You can erase everything except the nintendo 3ds folder - just make sure to make a backup on your computer.

a9lh will run you through getting FBI set up, and then yes, you can just install your gba game.

 

[Cortexfou]

I don't gonna erase everything because I have some games, saves, custom themes, badges, ect installed on my card. I'm gonna try to install now. I'll say you If it work

all the games and saves are saved to the "nintendo 3ds" folder, so deleting the other stuff is fine - especially if you make a backup of the other files/folders on your pc first.
