Downgrade your 3DS to 9.2.0

Why downgrade?

9.2.0-20 allows for custom firmware to be set up and provides the most compatibility with homebrew and 3DS flashcarts (such as Sky3DS or Gateway).

Requirements

YOU MUST DOWNLOAD THE CORRECT FILE OR YOUR SYSTEM WILL BRICK.

Install uTorrent to be able to open the file you download:

Prepare your SD Card

  1. Extract the sysDowngrader .zip to the root of your 3DS SD card
  2. Delete any “updates” folder already on your SD Card if there is any
  3. Copy the “updates” folder from the 9.2.0 firmware .zip to the root of your SD card
 Caution and Disclaimers:

  1. These tools have a very small chance of causing a “soft brick” on your 3DS once the downgrade is complete and the device reboots.
    If this happens it can only be fixed by using recovery mode (A + R + L + Up on the D-Pad) to update to the latest system version.
  2. If you are on version 11.0.0 thru 11.2.0, you MUST have downgrade your firmware using this guide FIRST.
  3. If sysDowngrader crashes at any point during the downgrade you must 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.

Downgrading your 3DS

  1. Boot into the Homebrew Launcher (hold down the R button on boot if you used my previous guide)
  2. Open sysDowngrader
  3. Press (Y) to downgrade to 9.2.0
    Downgrade your 3DS
  4. If you are stuck being unable to acquire the am:u service, power off your 3DS by holding the power button and try again (this can take many tries)
  5. Wait; do not touch anything even if it appears to freeze
  6. If, after around 30 seconds, it is still frozen, it is safe to power off and try again
  7. If you get an error before installation, power off your 3DS by holding the power button and try again (this can take many tries)
  8. If you get an error in the middle of installation, start from step 1 again.
  9. 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
  10. Clear Home Menu’s extdata by navigating to /Nintendo 3DS/(32 Character ID)/(32 Character ID)/extdata/00000000/ on your SD card
    • EUR Region: Delete 00000098
    • JPN Region: Delete 00000082
    • USA Region: Delete 0000008f
    • KOR Region: Delete 000000A9
    • TWN Region: Delete 000000B1
  11. Reinsert your SD card into your 3DS and boot
  12. If you still get a black screen after downgrading and deleting the folder, follow this troubleshooting guide
  13. Reinstall the Homebrew Launcher.

Now you can install custom firmware and most 3DS flashcarts will work!

    How am I supposed to downgrade if I can’t install homebrew?
