User:ManiacOfHomebrew/Installing boot9strap (MSET9-GM9)

Required Reading

This is an alternative to the normal MSET9 guide that allows you to use another already modded console to install boot9strap to an unmodded console. There's very little good reason to follow this guide considering the compatibility of MSET9 on different OS nowadays. If you do not know why you are following this guide, you should instead return to the main guide.

What You Need

• Two 3DS family consoles
  • The source 3DS: the 3DS family console that is already running boot9strap
  • The target 3DS: the 3DS family console on stock firmware
• Any adapters needed to insert the SD card from the target 3DS into the source 3DS
• The latest version of MSET9
• The latest version of MSET9-GM9 (the MSET9-GM9 .zip file)
• The latest version of GodMode9 installed onto the target SD card

Instructions

The SD card referred to throughout this guide is the SD card from the target console.

On this page, you will use the MSET9-GM9 script, which is used to trigger MSET9. While the script is in progress, user data will temporarily disappear but will return upon the completion of this page. If you get an error when running the script, please join Nintendo Homebrew on Discord and ping @_themaniac for assistance.

Section I - Prep Work

In this section, you will prepare the MSET9 exploit by temporarily creating a new HOME Menu profile with no user data, and then setting up that profile with only the minimum data required for MSET9 to trigger. Your existing user data will disappear, but will come back when you are finished with this page.

• On the next page, you will install useful homebrew applications to complete your setup.
