Hacking .cia "Invalid Signature""

[voldek]

So I go to the rxTools through DS profile and boot it in emunand. If I check version in options it says RX3D 10.1.27, original software is still in 4.4.x
I tried download .cia from various users (so the .cia itself isn't problem) and install them throught FBI manager but everything hit 100% and get's "Invalid Signature" error:

Install failed
Could not install app.
Raw Error: 0xd8e0806a
Module: AM (0x20)
Level: Permanent (0x1b)
Summary: Invalid argument (0x7)
Description: Invalid signature (0x6a)

I tried format emunand and setup everything again but the error appears. What should I do?

title.db missing?

 

[voldek]

No, if the title.db was missing there'll be "NO DATABASE" error.
Only information I can find is that Invalid signature means that the .cia itself is damaged, but I download them from various user so that can't be a problem.

That happens to me, too, when I try to install some games in sysNAND (MarioKart7 is one of them); FBI works flawlessly in emuNAND, though. It's not a problem related to .cias, devMenu lets me install them. Have you tried installing devMenu or BigBlueBox? Still getting that error?

I guess because you are checking the Version on the System Settings and exiting from there, you will not be on emunand with rxTools any longer. This is because the 3DS does a soft reboot when you quit the System Settings application. You could just drop some folders on your homescreens like "S","Y",S" and "E","M","U" to 100% safely identify the NAND which you've got booted at any moment. On the New3DS i additionally have 2 different colored Themes: Red for sysnand and Blue for Emunand
Of course this can only be really helpfull when you've got unlinked NANDs

You cannot boot FBI while out of emuNAND/sysNAND with rxMode on.

i believe i read somewhere that using bbm or dev men instead of fbi should fix this issue.

I tried installed .cia through BigBlueMenu and I still get the same error.

What do you mean? My OF is on 4.4.x, I start rxTools from DS hack and choose to boot rxMode in emunand. The emunand load succesfly, I can see change in the menu and if I decide to go to settings there's RX3D 10.1.x loaded (I know it boot to OF again when I close settings). I can only use FBI H&S in emunand too, and the error still appear.

I alomost give up, is there anything I can try?

 

[Earth97]

Have you tried devMenu or legit cias? Or installing FBI in sysNAND, booting rxMode in sysNAND and installing a .cia there?
That answer was for m00k00, what you're doing is ok.

Ironically, I got similar errors trying to install BBM ...finally figured it was because I already had DevMen installed and they use the same title ID

 

[voldek]

Or installing FBI in sysNAND, booting rxMode in sysNAND and installing a .cia there?

Nothing changed, I've got the same error.

I tried legit cias too and the error still there.

Which rxTools version are you running?

 

[voldek]

2.6

 

[Earth97]

Try to upgrade to 3.0 BETA. It's great for Old3DS.
You can find it in the rxTools thread, someone posted a dropbox file. Set the SD card following carefully the instructions.

 

[voldek]

Yet I heard that 3.0 isn't really wise choice and it's unstable a lot.

Yet I heard that 3.0 isn't really wise choice and it's unstable a lot.

About 20% of the time it won't boot to EmuNAND (it will lock up with some weird lines or whatnot on the screen), but when it does boot properly I've had no problems. Failing to boot doesn't really bug me anyway since it boots way faster than 2.6.

You've nothing to worry about, it's quite stable for Old3DS. Also, it seems you don't have those many options, it's worth a try.

Do you mean the version included in this guide?

Or this one?
