Part 2 (dev update)

What we are doing is mainly for ShadowNAND so you have some NAND tools. Basically, If you boot without SD, you will see all of Nintendo tools. What's better is that now, you can use the Micro SD card management tool on Old 3DS and it doesn't reboot the console.

DON'T DO THIS IF YOU HAVE A EUR/JPN OR N3DS OR USE GATEWAY. A GUIDE FOR EUR/JPN/GATEWAY/N3DS is coming soon.

##Overview

What we will be doing is first renaming our original boot.bin so you don't lose your original CFW. However, we will be using a developer version of Luma3DS to make sure it works with the dev firmware. After that we will be running a downgrade in order to get the tools, then update back to 11.0 so that you can log on to the eshop.

##What you need

• The latest developer commit of Luma3DS
• The latest release of Luma3DS
• The latest release of sysupdater
• Dev & Factory Titles
• Retail Encrypted DevApps
