### Required Reading
|
|
|
|
This page prepares consoles with an existing modern boot9strap installation for reinstallation and/or updating of custom firmware applications. It can also be used in the event of a lost or corrupted SD card.
|
|
|
|
Your SD card must be formatted as FAT32 to follow this guide, or else the 3DS will be unable to recognize it. If your SD card is not yet properly formatted, use one of these pages to format it, depending on your operating system: [Windows](formatting-sd-(windows)), [Mac](formatting-sd-(mac)), [Linux](formatting-sd-(linux)).

### What You Need
|
|
* The latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) (the Luma3DS `.zip` file)
|
|
|
|
### Instructions
|
|
|
|
1. Insert your SD card into your computer
|
|
1. Copy `boot.3dsx` and `boot.firm` from the Luma3DS `.zip` to the root of your SD card, replacing any existing files
|
|
+ The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
|
|
1. Reinsert your SD card into your console
|
|
1. Power on your console
|
|
