If you are unable to boot your 3DS, please look for the section relevant to you, and follow the instructions. Once a solution works for you, you can proceed on with the main guide (The section is fairly long, try using Ctrl+F to search for your issue.) {: .notice--primary}

If you still cannot solve your issue and need to reach out for help, please paste the contents of all relevant .log files from the root of your SD card into a Gist, then come for help prepared with a detailed description of your problem and what you've tried. {: .notice--info}

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.

What you need

Instructions

  1. Copy GodMode9.bin from the GodMode9 zip to the /luma/payloads folder on your SD card and rename GodMode9.bin in /luma/payloads to up_GodMode9.bin
  2. Reinsert your SD card into your 3DS
  3. Open GodMode9 from arm9loaderhax by holding (Up) during boot
    (Be VERY careful with this tool, it can brick you if you misuse it, even with arm9loaderhax installed!)
  4. Navigate to SYSNAND CTRNAND -> title -> 00040010
  5. Navigate to the folder for your device and region:
  • Old 3DS EUR: 00022300 -> content
  • Old 3DS JPN: 00020300 -> content
  • Old 3DS USA: 00021300 -> content
  • New 3DS EUR: 20022300 -> content
  • New 3DS JPN: 20020300 -> content
  • New 3DS USA: 20021300 -> content
  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)
  2. While holding the (R) trigger, press (Y) to create a new directory
  3. Press (A) to confirm the name newdir (it doesn't matter what it's called)
  4. Press (A) to unlock SysNAND writing, then input the key combo given
  5. Press the (L) trigger on each of the uppercase extension files (.TMD and .APP) to mark them
  6. Press (Y) to copy the files
  7. Navigate to newdir
  8. Press (Y) to paste the files
  9. Select "Move path(s)"
  10. The uppercase extension files will have been moved to the newdir directory
  11. Press (Start) to reboot
  12. Return to Installing arm9loaderhax and retry the FBI injection
  13. 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 Installing arm9loaderhax and retry the FBI injection

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

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

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

After System Transfering steelhax, it crashes to a black screen on 3DS #2

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

  1. Download the otherapp payload corresponding to 3DS #2'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 3DS #2's SD Card
    • Overwrite any existing files
  4. Hold (B) while launching Steel Diver: Sub Wars

After doing the DSiWare Downgrade, my hacked save is gone

  1. Reboot 3DS #1 while holding Start to launch Hourglass9
  2. Go to SysNAND Backup/Restore and restore SysNAND from NANDmin.bin (the one made before the system transfer)
  3. If you don't have the game at all, link the NNID you bought the game with to 3DS #2 and download it on 3DS #2
  4. On 3DS #1, do DSiWare Downgrade - Section III - Installing the save
  5. On 3DS #1, go to System Settings, "Data Management", "DSiWare", then copy your DSiWare game to your SD card
  6. Either put 3DS #1's SD card in 3DS #2, or rename the Nintendo 3DS on 3DS #2's SD card and copy the Nintendo 3DS folder from 3DS #1's SD card to 3DS #2's SD card
  7. On 3DS #2, go to System Settings, "Data Management", "DSiWare", then copy your DSiWare game to the system
  8. Return your SD cards to normal, then continue with the DSiWare Downgrade

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
  2. Try checking your SD card file system with something like fsck.vfat <sd partition path> (on *nix) or CHKDSK <sd drive letter> /F (on Windows)
  3. Try backing up your SD card files, then formatting it and copying them back
  4. Try a different SD card

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
      • CHN Region: Delete 000000A1
      • KOR Region: Delete 000000A9
      • TWN Region: Delete 000000B1
  2. Try booting without any cartridges inserted (including flashcarts)
  3. If you have a hardmod and a NAND backup, flash the backup back to SysNAND.
  4. 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.
  5. Your 3DS may be bricked. For support, ask for help at #3dshacks on Rizon IRC or 3DS Hacking on Discord.

Black screen on SysNAND boot after installing arm9loaderhax

  1. Ensure you have a working payload.
    1. Check for the existence of arm9loaderhax.bin in the root of your SD card.
  2. Try resetting Luma's config and fix options
    1. Delete /luma/config.bin from your SD card
    2. Set your options when it boots
  3. Test booting Hourglass9
    1. On Luma3DS, hold Start on boot
  4. Try deleting home menu's extdata
    1. 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
      • CHN Region: Delete 000000A1
      • KOR Region: Delete 000000A9
      • TWN Region: Delete 000000B1
  5. Try booting without any cartridges inserted (including flashcarts)
  6. Try this test payload .
    1. Rename /arm9loaderhax.bin, if it exists, to something else.
    2. Place the arm9loaderhax.bin from the archive linked above in your SD root.
    3. Insert your SD card into your 3DS and power on.
    4. Press (A). Your 3DS should power off; this means arm9loaderhax is working and something else is broken; your device is not bricked.
  7. If you previously downgraded with Gateway, ensure that you are using the latest Luma3DS version (v6.2.3 or higher, at the least)
  8. Try following 9.2.0 ctrtransfer starting on Step 4.
  9. Ask for help at #3dshacks on Rizon IRC or 3DS Hacking on Discord.

Blue screen on boot (bootrom error)

  1. Your 3DS is bricked
  2. You will need to get a hardmod or repair / replace the device
