Note that if ye have any payload files other than `GodMode9.firm` in th' `/luma/payloads/` folder on ye SD card, holdin' (Start) on boot gunna display a "chainloader menu" where ye gunna have to use th' D-Pad 'n th' (A) button to select "GodMode9" fer these instructions.
## <a name="gw_fbi" />Cannot inject H&S on Gateway downgraded device
This is caused by Gateway implementing a very shoddy downgrade method, which leaves two versions of each app on the system. One of them is unused, but it confuses the H&S inject system, causing it to inject into the wrong one.
Note that if you have any payload files other than `GodMode9.firm` in the `/luma/payloads/` folder on your SD card, holding (Start) on boot will display a "chainloader menu" where you will have to use the D-Pad and the (A) button to select "GodMode9" for these instructions.
1. Notice that there are two sets of app and tmd files, one set with uppercase extensions (`.TMD` and `.APP`), and one set with lowercase extensions (`.tmd` and `.app`)
1. While holding the (R) trigger, press (Y) to create a new directory
1. Press (A) to confirm the name `newdir` (it does not matter what the folder is called)
1. Return to [Finalizing Setup](finalizing-setup) and retry the FBI injection
1. If this still doesn't work, move the uppercase extension files back to the `content` folder, then move the lowercase extension files to the `newdir` folder, then return to [Finalizing Setup](finalizing-setup) and retry the FBI injection
## <a name="ts_browser" />A browser based exploit is not working
Browser based exploits (such as browserhax or 2xrsa) are often unstable and crash frequently, but they can sometimes be fixed by doing the following steps
1. Launch the browser, then launch the browser settings
1. Scroll to the bottom and Initialize Savedata (it also may be called Clear All Save Data)
1. Try the exploit again
## <a name="ts_sys_down" />Black screen on SysNAND boot
1. Try booting with your SD card out, and then reinserting it after booting
1. Power off your device
1. Remove your SD card from your device
1. Power on your device
1. When the home menu appears, reinsert your SD card into your device
1. If this worked, you should clear Home Menu's extdata by navigating to the following folder on your SD card: `/Nintendo 3DS/(32 Character ID)/(32 Character ID)/extdata/00000000/`
+ EUR Region: Delete `00000098`

+ CHN Region: Delete `000000A1`
+ KOR Region: Delete `000000A9`
+ TWN Region: Delete `000000B1`
1. Try booting without any cartridges inserted (including flashcarts)
1. If you have a hardmod and a NAND backup, flash the backup back to SysNAND
1. Your device may be bricked. For support, ask for help at [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp)
## <a name="ts_sys_b9s" />Black screen on SysNAND boot after Installing boot9strap
1. Ensure you have a working payload.
1. Check for the existence of `boot.firm` in the root of your SD card.
1. Try resetting Luma's config and fix options
1. Delete `/luma/config.bin` from your SD card
1. Set your options when it boots
1. Test booting GodMode9
1. On Luma3DS, hold (Start) on boot
1. Try deleting home menu's extdata
