Homebrew "Invalid Signature" when installing .cia files - 10.4 Downgrade

[luvas66]

Hi guys,

im new in this forum, and have a question to do here.
Yesterday I made the downgrade my old 3DS XL in firmware version 10.4 following the tutorial video below:



Everything went without any error , I did everything in my Kingston micro SD card 32GB.
After completing the tutorial , I downloaded several .cias files related to games, created a " Games" folder at the root of the card, and copied the files on it .
When I started the 3DS , and accessed the FBI application to install the files , I entered the "Games " folder I had created , but had no file inside the same .
I returned to the computer and open the folder , and the file .cia really was gone.
After this fact , I tried to copy the .cia file in the root of the card, and started the 3DS again to see if I could find the file in the FBI application. This time I could find it, and start the installation, but literally all .cia files that I tried to install , the following error appears :

Install failed!
Super Street Fighter IV - 3D Edition (U)...
Source: SOURCE_FSFILE_WRITE (0X1c)
Module: MODULE_NN_AM (0x20)
Level: LEVEL_PERMANENT (0X1B)
Summary: SUMMARY_INVALID_ARGUMENT (0x7)
Description: DESCRIPTION_INVALID_SIGNATURE (0x6a)

Please guys, help me!
If I need to format the SD card, how I can do the whole process again , to be able to install the .cia files again ?
Excuse me , I 'm really new in all this.
And sorry for my bad english.

Thank you guys, in advance.

The signature is literally invalid. DG to 9.2 and use a CFW to patch signature checks.

You have to be running custom firmware before you can install CIAs. Check the tutorial section.

So, you successfully downgraded to 9.2, correct? If so, you need to use a CFW to patch out signature checks. Check out one of the CFW threads (ReiNand, Cakes, RxTools, etc.).

You have to be running custom firmware before you can install CIAs. Check the tutorial section.

I 'm running CFW through RxTools , according to the video I posted . It automatically starts as I turn on my 3DS , displaying the " FBI" menu to access the files .cia . This is not the CFW ?

I have performed the downgrade to 9.2 , and I'm already running CFW through RxTools that starts automatically when I turn on my 3DS , as is being done at the end of the video.

Then the CIA you're trying to install may be corrupt.

 

[MassExplosion213]

That or an incomplete downgrade.

 

[luvas66]

Then the CIA you're trying to install may be corrupt.

I think this is not possible as well , because I've tried 3 different files, and all give the same type of error when I try to install them.

That or an incomplete downgrade.

What is the correct procedure I have to follow after format my SD card with the 3DS already downgrade in version 9.2 ?

 

[Bros.Life]

Setup a emunand. After that you install a CFW.

 

[luvas66]

Anyone else?

Anyone else?

You need to install a custom firmware to bypass signature checks, such as AuReiNand or rxTools.

But I use a custom firmware on my 3DS , the RxTools , which starts automatically when I turn on the 3DS . After the initialization of this custom firware through RxTools , the FBI menu appears on my console menu.

FBI IS NOT A CFW!

 

[jefffisher]

it sounds almost as if you're just autobooting fbi through menuhax?

 

[luvas66]

Does anyone have any good tutorial for me to perform the installation of a good CFW from my 3DS in version 9.2 ? Something like this video that I posted.
I would like to follow step by step to give nothing wrong. Sorry for the ignorance but I am new in this.

 

[simbin]

I'm having the same problem, in addition to some other issues. I'm starting to suspect 10.6 downgrade.

Anyway, I'm on ReiNand emuNand 9.2.

FBI was injected to Health & Safety

I used it to install FBI.cia

Installing Legit CIA of Fire Emblem I had gave same error as Op.

May be a weird recommendation, but has anyone tried running this: https://github.com/svanheulen/downgrade_check/releases, to make sure that their 3DS fully downgraded?

Did you go to system setting to check the system info it should says something like RX-9.2-0.20U

It should look like this

Oh and how come you didn't wait for the release of the soft mod it came out two days ago and it works.

Yes but it's Rei

I also just tried Cakes with signature checking off and RedNand boot (same issue)

Also, I think these titles are just leftovers from newer than 9.2 firmware?
