Hacking 3DS NOOB PARADISE - Ask questions here

Who exactly discovered/found B9S?
Also, what is the highest current 3DS FW supported by Cosmo3DS atm?

Sighax was discovered by derrek, and its implementation (boot9strap) was made by a lot of people.

Sighax was discovered by derrek, and its implementation (boot9strap) was made by a lot of people.

If it was discovered by derrek, why did people implement it before he implemented it? Unless he gave out the knowledge and then deliberately didn't implement it himself for months? Not disputing just wondering

1. SciresM I think. 2. No idea, but why would you want it? Try https://yifan.lu

Also, What is wrong with Cosmo3DS FW according to you? Its definitely not Cakes or Corbenik, but at least its better than Palantine and post 7.05 Luma with the overrated Rosalina app.

Yifan lu made Cosmo3DS. If you don't want Rosalina then use the legacy version. You should actually ask for what you want not what you think you need.

there's plenty of reasons for this. someone else found another sighax signature before derrek decided to released it.

....... but Yifan Lu is the one who made Cosmo3DS.

if you really want to use it, then go to https://github.com/yifanlu/Cosmo3DS - keep in mind you likely won't receive support for it here due to no interest, and most people not even knowing how to use it.

Because all he did was say at 33c3 "Oh look at this nice exploit I found in the bootROM that allows us to sign our own firmwares. It has this <insert very simplistic explanation of the flaw>". Then, he said that each sighax signature would take 6 months to brute force. He did not give any code, or any dumps, or any other hints at all. If I recall correctly, it was a few months before boot9strap was released that he showed a sneak peek of some sighax installer. After that, SciresM released boot9strap and shortly afterwards d0k3 released the sighaxed firm installer (aka SafeB9SInstaller). Derrek, from what I was able to read, is all show and hoards a lot of knowledge.

So basically SciresM and others had to re-discover it, essentially. Derrek just announced that it existed?

Pretty much

For more info about what was going on with sighax: https://gbatemp.net/threads/sighax-updates-and-discussion-thread.454821/

The situation was this:
Derrek did dump the bootrom and provided a simple explanation of how he did it.
He did not make the bootrom public though. Nor any of the code he used.

This means someone would have to develop code that exploits the Bootrom pointers and leads them to dumper code to dump the bootrom. Which is unstable and likely needs you to have a hardmod to trigger this very early exception without the chance of killing your device.

I just got a R4i Gold 3DS RTS today. How do I set it up for running CFW on my N3DSXL? What exactly do I need?

Thank you! That's exactly what I was looking for!

Hi guys I'm having trouble updating an N3DS' B9S.

I cannot load into chainloader as pressing start does nothing on boot.

If I hold Select on boot I can get into the Luma 7.1 menu.

Please help.

What guide are you following?

This one here. Specifically I'm up to part 1 of Section II.

Do you have SafeB9SInstaller.bin in /Luma/payloads

 

[Quantumcat]

Make sure you have Luma 7.1 boot.firm on your SD card. This can happen if you put 8.1.1 on your SD card too early. Get it from https://github.com/AuroraWright/Luma3DS/releases

Negative. Just GodMode9.firm and SafeB9SInstaller.firm

I will try this now.

Yeah. Do as @Quantumcat said. For some reason I thought you said you were on Luma 7.0.5.
