9.2.0 Downgrade /9.2.0-downgrade.html

Some regions may downgrade to another version such as 9.1.0 or 9.0.0. This is fine as those versions function nearly the same for our purposes. {: .notice--success}

If you encounter this error and cannot use recovery mode, you can edit the connection settings as long as the 3DS completely fails to connect to any access point (such as if the point is out of range). {: .notice--info}

This version of sysDowngrader (which is compatible with >9.2.0 systems) uses an unstable exploit, and because of this it may take many tries to work. {: .notice--info}

{% capture notice-3 %} If sysDowngrader crashes at any point during the downgrade (which can happen occasionally), you can power off the system by holding the power button. You will be left with what's called a "partial downgrade" or "partial", which is recoverable.

Although a partially downgraded system may show 9.2.0 as the system version, you are not done. You must restart from the beginning of Section II and downgrade a second time to install any files that were not installed. browserhax will work for partial downgrades as long as you are using the recommended version of sysDowngrader, but you must replace browserhax_hblauncher_ropbin_payload.bin on your sd card with the one for 9.2.0 on your region (rename the downloaded ropbin to browserhax_hblauncher_ropbin_payload.bin) {% endcapture %}

{{ notice-3 | markdownify }}

If you are are between versions 11.0.0 and 11.2.0, you MUST have downgraded your NFIRM to successfully complete this part. {: .notice--warning}

You MUST downgrade with the correct pack for your console/region or you will BRICK. {: .notice--danger}

What you need

  • The Homebrew Launcher and an entrypoint (such as browserhax or SoundHax)
  • The latest release of sysDowngrader
  • The latest release of nimSM
  • The 9.2.0 downgrade pack .zip file for your device and region:

Instructions

Section I - Prep work
  1. Copy and merge the 3ds folder from the sysDowngrader .zip to the root of your SD card
  2. Copy and merge the 3ds folder from the nimSM .zip to the root of your SD card
  3. Delete any existing updates folder from your SD card if there is one
  4. Copy the updates folder from the 9.2.0 downgrade .zip to the root of your SD card
  5. Reinsert your SD card into your 3DS
Section II - Downgrading
  1. Get the Homebrew Launcher
  2. Launch nimSM
  3. Press (Y) to backup and zero out the nim savegame
  • This will prevent any "soft bricks" when downgrading the system
  • A "soft brick" is when the system displays an error screen on boot and can only fixed by booting updating to latest version with Recovery Mode (hold A + R + L + Up on boot)
  1. Wait for it to successfully back up and zero out the nim savegame
  • If it freezes while attempting svchax, power off your 3DS by holding the power button and try again (this can take many tries)
  • If it freezes while attempting to terminate the fs module, power off your 3DS by holding the power button and try again (this can take many tries)
  1. Press (Start) to reboot
  2. Open sysDowngrader
  3. Press (Y) to downgrade to 9.2.0
  • If it freezes while attempting svchax, power off your 3DS by holding the power button and try again (this can take many tries)
  1. Wait; do not touch anything even if it appears to freeze
  2. If, after around 30 seconds, it is still frozen, it is safe to power off and try again
  3. If you get an error before installation, power off your 3DS by holding the power button and try again (this can take many tries)
  4. If you get an error in the middle of installation, follow the instructions in the beginning for partial downgrades
  5. If you freeze on the "Rebooting in 10 seconds" line for longer than 10 seconds, it is safe to power off your 3DS by holding the power button
  6. 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
    • TWN Region: Delete 000000B1
  7. Reinsert your SD card into your 3DS and boot
  8. If you still get a black screen after downgrading and deleting the folder, follow this troubleshooting guide

Menuhax will no longer work, but you can use Homebrew Launcher (Browser) to get into the Homebrew Launcher. {: .notice--primary}
