3DS:Black screen unbrick

When a 3DS boots to a black screen instead of the HOME Menu, it is usually a bad sign. This page lists common troubleshooting steps to fix this issue.

The troubleshooting below should always be started at the first section. The troubleshooting will direct you to the next sections if necessary.

CFW Check
First, we will check if the console has CFW. This will help as it allows access to GodMode9, a helpful tool for troubleshooting and fixing issues.


 * 1) Power on your console while holding the  button
 * 2) * If your console boots to the Luma3DS configuration menu, press to save, then continue to the CFW troubleshooting section below
 * 3) * If your console doesn't boot to the Luma3DS configuration menu, do the same without the SD card inserted
 * 4) ** If your console does boot to the Luma3DS configuration menu, your SD card wasn't inserted correctly, re-insert it and try again
 * 5) ** If your console turns off right away, you have CFW and can continue to the CFW troubleshooting section below
 * 6) ** If your console doesn't boot to the Luma3DS configuration menu but black-screens, your console is likely bricked without CFW, and you should continue to the stock troubleshooting section at the bottom of this page
 * 7) *** To make sure of this, hold SELECT for seven seconds while the console is powered off, then power off again, hold, and then press - if the notification LED lit up a color or the fastboot3DS menu appears, then you have working CFW but something is interfering with Luma.
