3DS always boots into SafeB9SInstaller

SafeB9SInstaller.firm is currently set as your boot.firm, so your 3DS will always boot into it. To fix this:

1. When you see the key combo prompt, force power off your device by holding the power button for 15 seconds.

   Careful!

   Do NOT force power off the device if SafeB9SInstaller isn't idle (that is, you see a progress bar on the top)! If you do, you may brick the device!

2. Insert your SD card into your computer

3. Download the latest release of Luma3DS and copy boot.firm and boot.3dsx to the root of the SD card, replacing any existing files
4. Reinsert your SD card into your 3DS

It worked! It didn't work
