Homebrew SigHax Updates and Discussion Thread

Alright I'll post a screenshot aswell

Even if you have the files in the right place that doesn't mean they didn't get corrupted during download/transfer. Download fresh ones and try again.

Great redownloading the files worked thanks for quick replies guys.

No, it's not, it's only used when installing boot9strap itself or when using boot9strap to dump the bootroms/OTP. It's not needed for normal usage after install.

Yeah, I went back and checked the guide and saw that. I edited my post already.

Is it fine to remove the boot9strap folder and it's contents after installing? Or are those necessary files?
I ask because there was no list of required folders in the updating from a9lh to sighax part of the guide.

Yes it is. I tried it myself in O3DS and N3DS. My recommendation to know if you need a file or not in your SD card -if you are not sure about its usage- is to copy it to your desktop and remove it from your SD card. If you start your 3DS and everything works fine (3DS games, VC, DS games/cartridge, GBA games) then you don't need it. If it doesn't work then you need it. Enjoy!

EDIT: @addi33, as you are the OP, just telling you that Nintendolife and nintendoeverything haven't posted anything about Boot9strap/Sighax. It is a bit strange as they shared info regarding other exploits. This means this one is BIG!

They are different implementations of the same thing. I wouldn't recommend switching to base sighax because of the high brick chance just stay with b9s.

They are not.

See this and this.

Hey. I'm getting an annoying error by luma3ds updater when loading my custom .cfg file. Whenever I disable backups and logging from the v2.0 cfg file, it says invalid or wrong payload type, 'sighax'. Can someone please help me?

 

[KumpelKuerbis]

Is it possible to update luma with luma updater after installing boot9strap?

 

[pixelmasher]

Is it possible to update luma with luma updater after installiert boot9strap?

Yes, but nightly builds are currently broken. Stable should be ok.

You have to use the updated luma installer

 

[KumpelKuerbis]

You have to use the updated luma installer

so i have to install a new luma updater cia ?

 

[SG854]

you can scan a qr code to install it using fbi its faster that way.

If I understand the slides from SciresM correctly, sighax is an exploit in the boot9 checksum parser that lets people bypass the signature check at booting stage. Any firmware with sighax will bypass the check and thus be loaded successfully. B9S utilizes sighax to make its firmware "valid", and that firmware uses NDMA exploit to run some code that then loads an payload (like CFWs). The payload should have bootrom privilege right? How does it benefit CFWs from a player's view?

That's pretty much the gist of it. This is a much cleaner environment for developers, and additionally allows any user to dump Boot9 and their OTP on any version (allowing for title decryption on a PC and the death of xorpads). Additionally, boot9strap is installable on any version with just a hardmod (or dsiware).
