## <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 Decrypt9, causing it to inject into the wrong one.

## <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. Open the browser, then open the browser settings
    1. Scroll to the bottom and Initialize Savedata (it also may be called Clear All Save Data)
    2. Try the exploit again

## <a name="ts_safe_a9lh" />System boots directly SafeA9LHInstaller
You copied the wrong `arm9loaderhax.bin` file to your SD card (you were only supposed to copy the `3ds` folder and `SafeA9LHInstaller.dat` file from the SafeA9LHInstaller zip)    

1. Use the correct `arm9loaderhax.bin`
    1. Copy `arm9loaderhax.bin` from the Luma3DS `.zip` to the root of your SD card
    2. Reboot holding select and continue

## <a name="ts_safe_a9lh_screen" />SafeA9LHInstaller shows a glitched screen
This happens occasionally, but the reason is unknown. The buttons will still work, but the screen will be glitched looking

1. Follow instructions as normal
    1. Press (Select) and arm9loaderhax will be installed
    2. The console will reboot
        + If the console does not reboot, wait 10 seconds, then power off your 3DS by holding down the power button

## <a name="ts_steelhax" />After System Transfering steelhax, it crashes to a black screen on _the target 3DS_

This is because you selected the wrong version in the steelhax installer.

1. Download the [otherapp payload](https://smealum.github.io/3ds/#otherapp) corresponding to **the target 3DS's** version
    + Ignore the NFIRM being downgraded
    + Use the version displayed in settings
2. Rename the otherapp payload to `steelhax_payload.bin`
3. Copy it `steelhax_payload.bin` to the root of **the target 3DS's** SD Card
    + Overwrite any existing files
4. Hold (B) while launching **Steel Diver: Sub Wars**

## <a name="ts_dsiware" />After doing the DSiWare Downgrade, my hacked DSiWare does not work

3. Reboot **the source 3DS** while holding Start to launch Hourglass9
4. Go to SysNAND Backup/Restore and restore SysNAND from `NANDmin.bin` (the one made before the system transfer)
1. If you don't see the game at all on **the target 3DS**, link the NNID you bought the game with to **the target 3DS** and redownload it
  + You may have to delete the game from "Data Management" in the "System Settings" first
  + If **the target 3DS** is not the latest version, you may have to run ctr-httpwn to access the eShop
2. On **the source 3DS**, do the the save (and `.app` if you are using the `.app` page) injection steps
3. On **the source 3DS**, go to System Settings, "Data Management", "DSiWare", then copy your DSiWare game to your SD card
4. Either put **the source 3DS**'s SD card in **the target 3DS**, or rename the `Nintendo 3DS` on **the target 3DS**'s SD card and copy the `Nintendo 3DS` folder from **the source 3DS**'s SD card to **the target 3DS**'s SD card
5. On **the target 3DS**, go to System Settings, "Data Management", "DSiWare", then copy your DSiWare game to the system
6. Return your SD cards to normal, then continue with the DSiWare Downgrade

## <a name="ts_d9_backup" />Decrypt9 or Hourglass9 won't restore / can't find my NAND backup

1. Make sure you do not have any folder named "Decrypt9" on **the root** of your SD card
3. Try checking your SD card for errors using [H2testw (Windows)](h2testw-(windows)), [F3 (Linux)](f3-(linux)), or [F3X (Mac)](f3x-(mac))
4. Try backing up your SD card files, then formatting it and copying them back
5. Try a different SD card

## <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 3DS by holding down the power button.
    2. Take out the SD card.
    3. Power on the 3DS.
    4. When the home menu appears, reinsert your SD card.
    5. 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`
        + JPN Region: Delete `00000082`
        + USA Region: Delete `0000008f`
        + KOR Region: Delete `000000A9`
1. Try booting without any cartridges inserted (including flashcarts)
2. If you have a hardmod and a NAND backup, flash the backup back to SysNAND.
3. Try booting into recovery mode and updating your system.    
    *This probably will not work for an Old 3DS downgraded to 2.1.0*    
    **This will BRICK a New 3DS downgraded to 2.1.0**
    1. Power off your 3DS by holding down the power button.
    2. Hold L+R+A+Up.
    3. Power on the 3DS.
    4. If you enter safe mode, update your 3DS *only if you have an entrypoint for the latest FW version and it is possible to downgrade from it* and attempt the downgrade again.
4. Your 3DS may be bricked. For support, ask for help at [#3dshacks on Rizon IRC](https://www.reddit.com/r/3dshacks/wiki/irc) or [3DS Hacking on Discord](https://discord.gg/MWxPgEp).
