boot9strap is a firmware loader for the Nintendo 3DS. It is also an exploit for the ARM9 BootROM that allows for dumping of the protected area of the BootROM. It succeeded arm9loaderhax in May 2017.
Installation
This is the main firmware loader when using 3DS Hacks Guide. To update, follow the steps on Updating B9S.
To upgrade from an old setup:
- arm9loaderhax: A9LH to B9S
- menuhax: 3DS:Migrate from menuhax
- Gateway: 3DS:Migrate from Gateway
How it works
An in-depth presentation on how the BootROM signature parsing works and how boot9strap exploits it can be found here: SciresM's 33.5c3
