3DS:SafeB9SInstaller

From Hacks Guide Wiki
Revision as of 15:56, 25 April 2026 by Cominou (talk | contribs) (Sighaxed FIRM - file not found: added ".sha file not found" section (from source code))

SafeB9SInstaller is a tool used to install boot9strap. It supports a wide range of entrypoints, allowing it to be launched by numerous different exploits across every system version.

Usage

SafeB9SInstaller should be used alongside the guide or the alternate exploits article. A boot9strap folder containing boot9strap.firm and boot9strap.firm.sha is always required to be present on the root, and in most situations SafeB9SInstaller.bin needs to be placed on the root alongside it. Depending on how SafeB9SInstaller is being launched (e.g. with the Luma3DS chainloader) another file, like SafeB9SInstaller.firm may need to be used instead of SafeB9SInstaller.bin.

Features

  • Safe installation of boot9strap
  • Keycombo in order to confirm the user wants to proceed with the installation
  • Install boot9strap from arm9loaderhax
    • New 3DS users will need to provide a clean copy of sector0x96 as secret_sector.bin in order to revert arm9loaderhax
  • Backup firm0 and firm1 before installation
