## System update error after installing CFW ## "An error has occurred. Hold down the POWER button to turn off the power..." (black screen with text)
Occasionally, updates may fail to install after installing CFW. To fix this, reboot your device after each step of this section, then try updating again. Your `00000001.sav` and/or `otherapp.bin` files may be misplaced. Ensure that `00000001.sav` is in `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `title` -> `00040000` -> `0017c100` -> `data` and that `otherapp.bin` is on the root of your SD card.
If your files are in the correct locations, re-create the save using the [PicHaxx Save Tool](https://3ds.nhnarwhal.com/3dstools/pichaxx.php), then place it in `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `title` -> `00040000` -> `0017c100` -> `data`. Ensure that the file is named exactly `00000001.sav` and that you used your console's `movable.sed` to create it. Re-download the latest release of [universal-otherapp](https://github.com/TuxSH/universal-otherapp/releases/latest) and place it on the root of your SD card. Do not add the `.bin` extension if you do not already see it.
## Game starts normally
Your modified `00000001.sav` file may be misplaced, or you may have used the wrong `movable.sed` when creating it. Re-create the save using the [PicHaxx Save Tool](https://3ds.nhnarwhal.com/3dstools/pichaxx.php), then place it in `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `title` -> `00040000` -> `0017c100` -> `data`.
## Failed to open SafeB9SInstaller.bin
The file `SafeB9SInstaller.bin` is missing or misplaced. Download the latest release of [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases/tag/v0.0.7) and place it on the root of your SD card. Do not add the `.bin`extension if you do not already see it.
## Frozen on "Doing agbhax..."
There may be an issue with your `otherapp.bin` file. Download the latest release of [universal-otherapp](https://github.com/TuxSH/universal-otherapp/releases/latest) and place it on the root of your SD card. Do not add the `.bin` extension if you do not already see it.
## "PrepareArm9ForTwl returned error c8804631!"
You will need to follow an alternate method, like [BannerBomb3](bannerbomb3).

# Installing boot9strap (Soundhax)
## Red/purple/pink and white screen after running Soundhax
If your device is on system version 9.4.0, 9.5.0, or 9.6.0, you may be encountering a bug with universal-otherapp. Follow [Homebrew Launcher (Soundhax)](homebrew-launcher-(soundhax)) instead.
If your device is not on those firmwares, it likely indicates that you already have custom firmware. You should [check for CFW](checking-for-cfw).
## "An error has occurred, forcing the software to close..." (white message box)
There is an issue with your `otherapp.bin` file (it is missing, misplaced, or corrupted). Download the latest release of [universal-otherapp](https://github.com/TuxSH/universal-otherapp/releases/latest) and place it on the root of your SD card.
## "Could not play"
You have the wrong Soundhax file for your device and region, or your device is incompatible with Soundhax. In the latter case, you should update your device to the latest version and follow [Seedminer](seedminer).
## Failed to open SafeB9SInstaller.bin
The file `SafeB9SInstaller.bin` is missing or misplaced. Download the latest release of [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases/tag/v0.0.7) and place it on the root of your SD card. Do not add the `.bin`extensoin if you do not already see it.
## Frozen on "Doing agbhax..."
There may be an issue with your `otherapp.bin` file. Re-download the latest release of [universal-otherapp](https://github.com/TuxSH/universal-otherapp/releases/latest), rename it to `arm11code.bin`, and place it on the root of your SD card.
If you have a Taiwanese or Mainland Chinese unit (with a T or C in the version string, ie. 11.14.0-##T), join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) for assistance.
## "PrepareArm9ForTwl returned error c8804631!"

# BannerBomb3
## DSiWare Management menu does not crash
`F00D43D5.bin` is missing from `Nintendo 3DS` -> `<ID0>` `<ID1>` -> `Nintendo DSiWare`. Make sure that `Nintendo DSiWare` is correctly spelled and spaced. Uppercase/lowercase does not matter.
## DSiWare Management shows a question mark
There may be an issue with your `F00D43D5.bin` file (it may be corrupted or intended for the wrong 3DS). Re-create your `F00D43D5.bin`file with the [BannerBomb3 tool](https://3ds.nhnarwhal.com/3dstools/bannerbomb3.php), ensuring that you use the `movable.sed` file for your console.
## DSiWare Management menu crashes without purple screen
Ensure that `F00D43D5.bin` is the only file in `Nintendo 3DS` -> `<ID0>` `<ID1>` -> `Nintendo DSiWare`. If it is, then re-create it with the [BannerBomb3 tool](https://3ds.nhnarwhal.com/3dstools/bannerbomb3.php). If this fails, then custom firmware may have been uninstalled on this device in a way that makes this method impossible to perform. If this is the case, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) for assistance.

# Boot-related issues on modded devices
The steps detailed here generally assume that your device has a modern custom firmware setup (boot9strap + Luma3DS 8.0 or greater). If your console is running an older homebrew setup (for example, something based on arm9loaderhax or menuhax), you should update your setup before trying these instructions.

## My device gets stuck on a black screen, with a static blue light
The steps below can be attempted in any order, but are listed from least to most time-consuming.
1. Power off your device, eject the game cartridge if inserted, power on your device, then wait up to ten minutes. If your device boots within ten minutes, the issue has been fixed and is unlikely to reoccur
1. Rename the `Nintendo 3DS` folder on your SD card to `Nintendo 3DS_BACKUP`, then attempt to boot. If your device successfully boots, there is some issue within your `Nintendo 3DS` folder. Try clearing home menu extdata:
+ Navigate to `/Nintendo 3DS/<ID0>/<ID1>/extdata/00000000/`
+ Delete the extdata file corresponding to your region:
+ **EUR Region**: `00000098`
+ **JPN Region**: `00000082`
+ **USA Region**: `0000008f`
+ **CHN Region**: `000000A1`
+ **KOR Region**: `000000A9`
+ **TWN Region**: `000000B1`
1. Ensure that your device does not have ARM11 exception handlers disabled:
+ Power off your device
+ Hold (Select)
+ Power on your device, while still holding (Select)
+ If the "Disable ARM11 exception handlers" box is checked, uncheck it
+ If your device now boots to the "An exception occured" screen, follow [My device boots to an error screen](troubleshooting#my-device-boots-to-an-error-screen)
1. Try booting into recovery mode and updating your system:
+ Power off your device
+ Hold (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A)
+ Power on your device
+ If you were successful, the device will boot to an "update your system" screen
1. Follow the [CTRTransfer](ctrtransfer) guide

## My device boots to an error screen
### "An error has occurred: Failed to apply 1 FIRM patch(es)" or "An exception has occurred -- Current process: pm"
Your Luma3DS version is outdated. Download the latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) and place `boot.firm` on the root of your SD card, replacing any existing file. Make sure you are extracting the ZIP file with any tool other than WinRAR, as it is known to cause issues with 3DS-related files.
### "An error has occurred. Hold down the POWER button to turn off the power..."
ARM11 exception handlers are disabled, or custom firmware is not installed. Try enabling ARM11 exception handlers:
+ Power off your device
+ Hold (Select)
+ Power on your device, while still holding (Select)
+ If the "Disable ARM11 exception handlers" box is checked, uncheck it
### Some other error
Please take a photo of the error and join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) for assistance.

## My device gets stuck on a black light, and the blue light turns off
There is an issue with your `boot.firm` file (it is missing, misplaced, or corrupted). Download the [latest release of Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) and place `boot.firm` on the root of your SD card, replacing any existing file. Make sure you are extracting the ZIP file with any tool other than WinRAR, as it is known to cause issues with 3DS-related files.
If you hear a "popping sound", potentially accompanied with the backlight turning on for a split second, there is a hardware issue with your device (such as a disconnected backlight cable). You may be able to get your device to boot by holding it at certain angles.
## My device gets stuck on a blue "Bootrom Error" screen
Your device is likely hard-bricked. You will need to buy an ntrboot flashcart to reinstall boot9strap in order to attempt to fix your device. This may also indicate a hardware issue which cannot be fixed. In any case, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) for assistance.
+ There is a possibility that someone has set a boot-time splash screen that just looks like a brick. Please try leaving your device turned on, waiting on the blue screen, for five minutes.

# Functionality-related issues on modded devices
## DSi / DS functionality is broken, or has been replaced with Flipnote Studio
1. Download the latest release of [TWLFix-CFW](https://github.com/MechanicalDragon0687/TWLFix-CFW/releases/latest) (the `.3dsx` file)
1. Power off your device
1. Create a folder named `3ds` on the root of your SD card if it does not already exist
1. Copy `TWLFix-CFW.3dsx` to the `/3ds/` folder on your SD card
1. Reinsert your SD card into your device
1. Open the Homebrew Launcher
1. Launch TWLFix-CFW from the list of homebrew
1. Press (A) to uninstall the broken TWL titles
1. Press (Start) to reboot the device
1. Perform a System Update by going to System Settings, then "Other Settings", then going all the way to the right and using "System Update"

1. Once the update is complete, tap "OK" to reboot the device
## GBA Virtual Console and/or Safe Mode functionality is broken
Your device is running Luma/AuReiNand 6.6 or older, likely via arm9loaderhax. You should follow [A9LH to B9S](a9lh-to-b9s) to update your device to a modern custom firmware environment.
## Extended memory mode games are broken
This can occur after a CTRTransfer or region change on Old 3DS / 2DS. You will need to system format your device to fix this issue.
